Overall, the first diagram shows all the steps required for the production of cement like crushing, mixing heating, grinding, packing and the usage of the final product along with few other raw materials. Whereas, concrete production is depicted in the second diagram. Cement production involves more steps as compared to the production of concrete but the former requires less number of raw materials than the latter. Concrete is the final output which is directly used for the building process, whereas cement is a semi-finished product and needs further processing.
Firstly, limestone and clay are turned into powder by putting them in a crusher. This powder is then mixed in a mixer, after which it is put in a rotating heater. Here, this mixture is heated by applying heat externally. Then the mixture passes through a grinder, and fine cement is produced, which then is packed in a bag for further usage.
Secondly, this cement along with water, sand and gravel, as per specified proportions, is put in a concrete mixer. The concrete mixer rotates, thereby producing the final output, i.e. concrete which is directly used for building purposes.

The cement production involves five stages, a straightforward process that begins with the mixing of raw materials and reaches a finale in the packaging of new cement. Making concrete is a simple process that involves mixing four ingredients in a concrete mixer.
Overall, the first diagram shows the equipment and the process of cement making. Limestone and clay are simultaneously passed through the crusher to form powder which is then mixed before passing it through a rotating heater. Once heated, this mixture is ground through a grinder. Now that the cement has been produced, it is packed into bags.
At the same time, the second diagram shows the concrete production process. For the production, the concrete mixture needs four ingredients and a concrete mixer. The concrete mix comprises half a portion of gravel (small stones), a quarter portion of sand, 10% water and 15% cement. All of these are added together in a cylindrical drum and rotate until the concrete is produced.

It is clear that there are five stages in the production of cement, beginning with the input of raw materials and ending with bags of the finished product. To produce concrete, four different materials are mixed together.
At the first stage in the production of cement, limestone and clay are crushed to form a powder. This powder is then mixed before it passes into a rotating heater. After heating, the resulting mixture is ground, and cement is produced. Finally, the cement is packaged in large bags.
Cement is one of the four raw materials that are used in the production of concrete, along with gravel, sand and water. To be exact, concrete consists of 50% gravel, 25% sand, 15% cement and 10% water. All four materials are blended together in a rotating machine called a concrete mixer.

The figures illustrate the steps and tools which are used in the cement-production process, and how to make concrete for building purposes using cement. Overall, it can be seen that concrete-making process is shorter than cement-making process.
First of all, limestone and clay are basic ingredients which are crushed to result in powder. The result passes throughout the mixer and then the rotating heater in order to heat it. Furthermore, it is grind to produce the cement. Finally, the cement is packed and ready to use and to sell in store.
Next, the cement is very essential to be used in the concrete-making process. The proportion of cement which is taken to create concrete is 15%. In addition, the percentage of small stones is 50%. It is twice of the proportion of sand (25%) and five-fold of the proportion of water (10%). To make the concrete, all ingredients are mixed in concrete mixer as the first as well as the last step of the concrete production.

The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
At the first step of the cement production, limestone and clay are crushed into powder. The process continues with mixing this powder in a machine called mixer. The powder is then moved to the rotating heater where it is heated to high temperature. The next step is the material being ground and becoming cement. At the final stage, cement is packaged into bags and ready to produce concrete.
The first step in the process of making concrete is mixing cement, water, sand and gravel in the proportion of 15%, 10%, 25% and 50% respectively. This mixture is then put into a concrete mixer to produce concrete, which is used for building purposes.
This IELTS diagram model answer is estimated at band score 9. It is possible to have a diagram in your IELTS writing task 1 academic paper. A diagram is also known as a process. The diagram shown below is from IELTS Cambridge Book 8, Test 3.
The diagrams illustrate the way in which cement is made and how it is then used in the process of making concrete. Overall, limestone and clay pass through four stages before being bagged ready for use as cement which then accounts for 15% of the four materials used to produce concrete. While the process of making cement uses a number of tools, the production of concrete requires only a concrete mixer.
In the first stage of making cement, limestone and clay are crushed together to form a powder. This powder is then combined in a mixer before passing into a rotating heater which has constant heat applied at one end of the tube. The resulting mixture is ground in order to produce cement. The final product is afterwards put into bags ready to be used.

The above diagram illustrates the stages and equipment used in the cement making process, and how cement is used in the production of concrete for building purpose. Cement is one of the four ingredients involved in production of concrete. Initially, ground limestone and clay are added to a crusher to break into smaller particles. This fine powder is next added to a mixer to create a perfect blend of the two. Later the mixed powder is sent into a rotating heater, to which heat is supplied from one end. After heating the mixture, the heated mixture is added to a grinder to make a fine powder. The obtained fine powder is cement. Cement is packed in bags and distributed accordingly. Regarding the second diagram, concrete consists of mainly gravel, which is broken stone and accounts to 50% of the ingredients. Other ingredients are cement (15%), water (10), sand (25%) and gravel (50%). All ingredients are added into a concrete mixer is said proportions and mixed thoroughly to produce concrete.
Please evaluate. The diagram illustrates the various stages employed in the production of cement and also the method used to make concrete. Overall, limestone and clay passes through four main stages in order to make the final product, which then further added with three more ingredients in a mixer to produce concrete. In the production of the cement several tools along with heating medium are used whereas concrete making process needed only a mixer.
Initially, limestone and clay passes through a crusher which crushes them into a powder. Now this powder passes through a mixer, which mix it well. Next stage is rotating heater, where continuous heat is applied after this the heated powder allowed to pass from a grinder which shapes it into the final product. From here the cement is poured and packed into bags in order to process it for commercial purposes.
For concrete making, mainly four ingredients Gravels, sand, cement and water in particular proportions are used (50%, 25%, 15% and 10% respectively). All four are fed into a mixer, which rotates constantly and mixes them to form the concrete.
The diagram illustrates the production of a cement which is then used to from the concrete. overall, the limestone and clay are used to form cement after passing through several steps like crushing, mixing, heating and grinding. this cement is then used to form the concrete by mixing with other ingredients in a concrete mixer. Firstly the limestone and clay are crushed to form a powder this powder is then mixed together in a mixer for passing through a rotatory heater where constant heat is applied. Furthermore this heated powder is then grinded to form cement which is stored in bags for delivery regarding second diagram the concrete is made by adding cement and other two ingredients like water and sand into a main ingredient which is gravel(50%) that are fine stones . All these ingredients are mixed together in a concrete mixer to form concrete which is used as a building material.
The diagram shows the ways in which bricks are made for the building industries. Overall, there are eight stages in the whole producing process, beginning with the digging up the clay and culminating in delivery. In the initial stage of the process, the clay used to make the bricks is dug up from the ground by a large digger before placing onto a metal grid which is used to turn the bricks into smaller pieces. A roller assists in this process. Following this, sand and water are added to the clay in order to turn into bricks by either placing it into a mould or using a wire cut. Next, these bricks is placed in a drying oven to dry for 24-48 hours. Once the bricks have gone through heating and cooling process, they are then heated in a kiln at a moderate and then a high temperature ranging from 200 C 1300 C, followed by cooling process in a cooling chamber. Having been left in the chamber for 48-72 hours, the bricks are then packed and delivered to their destinations. Hey Liz, I am Shukhrat from Uzbekistan. Can you have a look at this? Does this process deserve to get high band score in IELTS?
Hello Liz I am an ardent fan of your tutorials..i just want to ask one thing about task 1..shall we write it in present tense or past tense if nothing is mentioned about time like in process tyoe questions
The diagrams explains the steps and equipments utilize in the production of cement and the way in which concrete are formed for housing reasons. Overall, it can be deduced that the process of cement making used four equipments and two materials. In contrast, concrete was produced from four materials that was mixed together in one machine which rotates in a gradual motion.
First of all, the production of cement was made with limestone and clay which was crushed to powder and then passed through the mixer. Then, the materials was heated at the end of the rotating heater tube before it was grounded. Later on, the cement produced was packed into bags.
However, in the production of concrete, four materials were used compared to cement production that utilized two resources. 15% of cement which was made from limestone and clay was added to 25 percent of sand. Two times the size of sand represents the size of gravel which is small stones. Moreover, 10% of water was also added. All this material were mixed in a concrete mixer which rotates in a gradual movement.
There are no fixed rules. Diagrams generally have a very very short introduction. Sometimes it is no more than 10 words. For that reason I put the overview in the same paragraph. Its fine to do that. For all other task 1, I keep it as a separate paragraph. The most important thing is using the word overall to indicate to the examiner that it is the overview and making sure all key features are highlighted.
Overall, cement manufacturing takes four steps, beginning with crushing and ending with cement in bags. Regarding concrete production, different materials in constituencies are added/mixed to under rotation to make concrete.
Cement making steps are as follows: First and foremost, inputs namely; limestone and clay are put in a crusher where they are grinded to produce powder. Then, the material is channeled into a mixer where it is mixed thoroughly. The next stage involves passing the powder into rotating heater where heat is applied, the resource is rotated consequently, as heater rotates. The final stage focuses on the by-product which is crushed under grinder to produce cement which is put in bags.
Looking at concrete production diagram, initials stage: water (10%), cement (15%), sand (25%) and gravel (50%) are added together in concrete mixer, then, the mixer is put under rotation and the inputs are mixed to produce concrete.
The first stage in the production of cement is crushing ofboth limestone and clay to give a fine powdered mixture,after which it is transported into the mixer for thorough mixing. Next the mixture enters the rotating heater were heat is directly acted upon it. Then the heated mixture is poured into the grinder for more grinding of the particulars. The result is cement and then they are packed into bags for distribution and use
The making of concrete requires the combination of cement (15%), water(10%), sand (25%) and small stones called gravel also by 50%). The composition is poured into the concrete mixer for proper mixing of every ingredients.
This example is helpful for me and i learnt lot of things related to way we can use connectors include then and afterwards . I want next example about flow chart and pie chart. Thanks if you read it then comment also.
Hi liz, Thanks for your up-to-date informations. I want to ask a question that is it okay to write a overveiw in 2nd paragraph and again in the end add a conclusion paragraph in another way, I mean by another prospective in writing task 1?
Hi Liz, I cannot upload answer to first IELTS Bar Chart Practice Sample question ( men ,women and children eating five portions of fruits and vegetables). Please share a link for the answer. Thank you.
In cement production there are 4 stages involved. In the first stage limestone and clay are crushed to powder form. This then passes through a mixer into a rotating heater, which is supplied with constant heat at one end. Afterwhich, the mixture is ground to develop cement. This final product is bagged thereafter.
The process of concrete making involves 4 items, cement(15%), sand(25%),gravel(50%) and water(10%). All these ingredients are mixed in a concrete mixer which rotates clock-wise.This process results in the formation of concrete.
Hi, Liz. Firstly, Id like to thank you for these great lessons which are very helpful for me in preparing my upcoming academic IELTS test. Secondly, Id like to ask you if we are allowed to use/draw an arrow in the writing tasks? You know, to add some words that weve forgot to mention earlier. And when we use pen in writing tasks, is it okay to cross out some words, even a long sentence?
The examiner only sees the answer sheets. So you can draw, underline, , make notes, plan etc all over your question paper for listening, reading and writing. See this page: https://ieltsliz.com/ielts-help-faq/ and this page: https://ieltsliz.com/deleting-words-in-ielts-writing/. You can find all my tips on the main pages of this site which you access through the RED BAR at the top of the website.
Hi Liz, first of all, thank you for your great advice. I was wondering about the format of writing. Are we allowed to leave space in the first sentence of every paragraph? (just to indicate that there is a new paragraph starting ?
A process is another name for a diagram. All writing task 1, including diagrams and maps, MUST have an overview. It is the most important statement/paragraph in your task 1 writing. For diagrams, state the key stages. For maps, state the key changes (if it is time related) and/or the main features.

The first diagram explains how the cement is produced in a cement making factory using various materials and equipment and the second diagram shows the way of making concrete using cement for buildings purposes.
Limestone and clay are used as main raw materials in the cement production. In the first step, these two materials are crushed and converted into powder form using a crusher and mixed in a huge mixer. Then, this mixed powder goes through a special rotating heater which has 45 degrees angle and a heavy flame spreads from top to bottom. The heated powder which comes out of the rotating heater is ground and make cement as the final production. Then the cement is packed and distributed throughout the country. As it is explained in the second diagram gravel (50%), sand (25%), cement (15%) are mix together with water (10%) in a concrete mixer to make concrete for buildings.
Sample Answer 1: The given diagram shows the process of cement production and then how this cement is used for concrete production. As is observed from the graph, cement production involves some complex processes and concrete production is done using the water, cement and sand in a concrete mixer.
The first diagram depicts that, to produce cement first the limestone and clay are crushed and the produced powder from this is passed through a mixer. The power is then passed via a rotating heater where heat is supplied constantly and this process creates the raw cement materials which are passed on a grinder machine to finally produce the cement. The cement is then packed and marketed for sale.
The second diagram presents how the concrete is produced for housing and building work. In the first stage, 15% cement, 10% water, 25% sand and 50% small stones are mixed in a concrete mixer machine and the machine rotates fast to have the ingredients mixed together to create the concrete. Sample Answer 2: The two diagrams illustrate the cement-making process. We can see from the given illustration that cement is manufactured first, and then its used in the concrete production.
In the first diagram, we can see that limestone is the raw material with which clay added. Firstly, the two materials are crushed to form the powder. Then this powder passes through a mixer and a heater through which the powder is exposed to flame. The powder now is in the form of a paste. This paste is grinded to be cement to pass through the last process; packing in bags.
The second diagram shows that cement can be used to produce concrete. This process is simpler than cement production; concrete is a mixture of 15% cement, 10 % water, 25% sand and 50 % small stones which are named as Gravel. The four elements are poured in a huge mixer which rotates producing concrete. We can see that once the cement is produced by several steps and equipment, it can be used in other less complicated processes, for instance, concrete production.
Sample Answer 3: These two diagrams reveal the flow diagrams of both cement and concrete production processes with necessary equipment and materials that are used. Mainly, both processes have similarities and differences. They are similar because each of them has more than one input and a single output. On the other hand, they differ in the number of production steps.
In the cement production diagram, firstly, limestone and clay are gathered and passed through a crusher. Then, the powder obtained from crusher is moved to the mixer to make a homogene mixture. Next, rotating heater welcomes the material from the mixer. After heating step, resulting material flows on the grinder. Finally, cement becomes ready to be packed in bags at the end of the grinder.
In the concrete production diagram, the process contains only one step to have concrete material that is mixing. Cement, water, sand and gravel which is a general name for small stones are all mixed in a rotating concrete mixer in precise proportions such as 15%, 10%, 25% and 50% respectively.
To begin with, cement is produced by combining raw materials like limestone, clay, which are processed in a tool called crusher. Those all items are mixed together to create a perfect blend. The blend, furthermore, goes into to a rotating heater. As it is in the rotating heater tube, heat is introduced from the end of the tube before the blend is actually dropped onto grinder. Then, after all the systemic process, the mixture turns into some cement which is then packed into bags.
Meanwhile, to create concrete, the main components of construction systems are gravel, cement, water, sand and a concrete mixer to blend all the materials. Gravel or small stone is the major and biggest component needed and accounts for 50% among all materials. There are, however, some other materials like the sand which is mainly used and comes in the second place and is accounted halved from gravel, followed by cement and water. The cement accounts for 15% compared to among all materials used to construct a new real construction. All the material is mixed together by a concrete mixer.
Overall, the steps of making cement are more complicated and require advanced machinery while concrete production requires mixing required components in the right proportion in a simpler machine. While heat is required to produce cement, no heat penetration during the combination period of making concrete is required.
Overall, in Cement production, the process is passed through eight stages while concrete production had five ingredients are used Moreover, gravel proportion was half among others while water was less used.
In order to, Cement production to being Limestone and clay with two materials are crushed through a crusher and make powder. It can be seen that then, the powder goes in a kind of rotating heater and works with heat. After that all materials go into the grinder and finally, cement is ready to use also kept in bags.
Furthermore, Concrete production the gravel material highest used of 50% while other materials like cement, sand and water were used 15%,25%, and 10% respectively. Finally, all ingredients are going into the mixer and it had rotated and concrete finally ready to use construction purpose.

The two diagrams represent the production process of cement and the subsequent production of concrete used for building purposes. The production of cement is divided into three main parts; the crushing and mixing of basic raw materials, the heating process and finally the grinding process. Alternatively, the concrete production production of concrete is less complex and consists of mix involves different mixing materials. The cement production production of cement begins with limestone and clay passing through a clusher crusher. Then the The powder generated in this step is put into a mixer and, after it this, lead passed through a pipe into a rotating heater that is maintained by an external source of heat. The mix obtained passes through a grinder in order to become the cement we all know/the cement we are all familiar with. This final product then is put into placed into/packaged in bags. The concrete production production of concrete is simpler and doesnt involves neither heat nor different a series of separate steps. It consists in of a mix of materials. The quantity of each material is well definite defined:; half of it must be composed by of small stones known as (gravel), while the other half is divided in comprised by 25% of concrete, 10% of water and, finally,15% of concrete. All these substances/materials are put into a concrete mixer that rotates until the concrete becomes ready to be used for use.
The production of cement starts with the use of limestone and clay, which are crushed into a powder thanks to a machinery called crasher. Then, the powder moves through a pipeline until it reaches a rotating heater. As the name suggests, this machinery heats the powder up while rotating. Then, the material obtained in the previous stage moves towards a grinder. The productive process concludes with the obtaining of cement which is finally bagged.
The production of concrete requires the use of four materials in different proportions. Specifically, it requires 10% of water, 15% of cement and 25% of sand. The largest share is gravel, consisting of small stones, which amounts to 50%. These materials are put in a concrete mixer which makes them rotate and combine. Once this process is over, concrete is obtained.
The two diagrams illustrate the phases steps and the equipment needed for the production of cement and concrete. Cement is one of the major ingredients in concrete, which Concrete, is used for the construction of buildings and roads., is made starting from cement.
Overall, the production of cement is divided into different stages, requiring many equipment. (equipment is non-count. You cannot write one equipment, five equipments or many equipments) Concrete production, instead, is a shorter process.
Overall, the production of cement requires several stages involving crushing, mixing, heating and grinding, whereas concrete requires only one step, mixing. However, cement uses only two raw materials, half as many as concrete.
The production of cement starts with the use of limestone and clay, which are crushed into a powder thanks to in a piece of machinery called a crasher. Then, after being thoroughly mixed, the powder moves down a conveyer through a pipeline until it reaches a rotating heater. As the name suggests, this device machinery heats the powder up while rotating. Then, the material obtained in the previous stage moves towards a grinder. The productive process concludes with the obtaining of cement which comes out of the grinder and is put into bags. is finally bagged.
The production of concrete requires the use of four materials in different proportions. Specifically, it requires 10% of water, 15% of cement and 25% of sand. The largest share is gravel, consisting of small stones, which makes up the remaining amounts to 50%. These materials are put in a concrete mixer which makes them rotate and combines them together. Once this process is over, concrete is ready to use. obtained.
Here is a conveyor. There are many types of these. They are mostly used indoors in factories, but also in airports to deliver baggage to passengers. The close up shows gravel in a conveyor, being carried from one place to another.
In the production of cement, the initial stage requires a mixture of limestone and clay. It will be then placed into a crusher which transforms the mixture to a certain amount of powder. After going through a mixer, the powder enters a heating process where a rotating heater will increase its temperature.
Processed cement is required for the production of concrete which involves fewer steps but a larger number of initial components. A mixture of gravel, sand, cement and water with respective proportions of 50%, 25%, 15% and 10% is prepared. The next stage witnesses the appearance of a huge concrete mixer which plays the role of processing the initial mixture of 4 components and transforming it to finished concrete.Get in Touch with Mechanic
