IELTS Writing Task 1: diagram introduction & overview

To write an introduction about a process diagram, just paraphrase the question statement as usual.

For the overview, here are some general things that you could mention:

- the number of stages in the process
- where / how the process begins and ends
- the items (e.g. materials) involved in the process

Let's return to the 'cement' task and write the introduction and overview.

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.

Introduction and overview:

The first diagram illustrates the process of cement manufacture, and the second diagram shows the materials that go into the production of concrete.

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.

[Muhammad Sohail]

cement production industry is flourishing rapidly these days. cement production involves five processes. First of all lime stone is crushed with lime in crusher followed by mixing and rotating the mixture in the heater rotator. After that grinding is done and finally cement is packed in bags.
The 2nd figures illustrates the usage of cement in the construction. The concrete is prepared by mixing water, gravel, sand and cement. the ,mixture of these items is called concrete and used for construction of buildings.

The first diagram illustrates the process of cement manufacture, and the second diagram shows the materials that go into the production of concrete.

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 of producing cement, limestone and clay are put in a crushing machine, and the result is a powder combination of these materials. It then passes a mixer and heated afterwards in a rotating heater at the second and third stage. Looking at the fourth and final stage of cement production, a grinder is used to ground this to make it into a cement, ready to be packed in bags and piled.

Looking at concrete production, different proportion of four raw materials are mixed altogether. 50% of gravel, 25% of sand, 15% of cement and 10% of water are all placed and combined in a concrete mixer that moves in a clockwise manner.

-> It is then passed through a mixer in the second stage, and in the third through a rotating heater. In the fourth stage it is ground up .... and finally it is packed ....

-> different proportions

At the first stage in the process of producing cement, limestone and clay are crushed together into powder. Then, the powder is mixed before being heated in a rotating heater.In the next step, the resulting mixture is ground into cement. Finally, the produced cement is packed in bags.
In order to manufacture concrete, cement is mixed together with water, sand and gravel in a concrete mixer. Specifically, cement accounts for 15% of the mixture, and the proportions of water, sand and gravel are 10%, 25% and 50% respectively.

[Prab]

The diagram illustrates the way in which cement is made and how it is then used in process of making the concrete.

Overall, the limestone and clay pass through fivestages before being bagged and ready for uses as a cement which then accounts for 15% of the four materials used for produce the concrete. While the process for making cement uses the number of tools, the production concrete requires only a concrete mixer.

In the first stage of making the cement, limestone and clay are crushed together to form of powder. The powder then combined in the mixer before into a rotating heater which has constant heat applied to end of tube. Next, it put on grinder and resulting mixture produce and ready for bagging.

Regarding the second diagram, the concrete mainly consists of gravel, which is smaller stones. The other material used are 25%(sand), 15% cement and 10% water. These all are put into the concrete mixer which continues rotates to combine the material and produces the concrete.

a) "Illustrate" tends to mean "gives an example of", rather than explaining the process or situation in general. "The diagram shows" would be more accurate.

[colette]

It might be worth mentioning that the powdered mix of limestone and clay is transferred from the mixer to the heater by means of a pipe, and from the heater to the grinder along a conveyor belt.

[fatemeh]

the diagrams depict how cement is produced and the process of concrete manufacturing for making structures.
it is clear that row materials go through five stages to produce cement. in the second diagram, cement, and three other materials are poured into a mixer in order to manufacture concrete.

[Prab]

@colette

Thank you so much for your help i really appreciate it.

[Nicole]

The diagrams illustrate the process of making cement in order to produce the ingredient of concrete for construction.
Overall, limestone and Clay is the ingredient of cement product. After four stages of different instructions, the cement has been made to provide the element of concrete product. Adding cement with sand, water and gravel in the mixer, it can produce concrete for building.

[Klaus]

A formulaic approach from Simon's previous process description:

The diagrams illustrate the process of making cement and the process of producing silk cloth concrete.

There are five main stages in the life cycle of the silkworm cement production , from eggs raw materials to adult moth finished product. The process of silk cloth production involves just one step, from silkworm cocoon the four ingredients to silk material ready-to-use/pour concrete.

[Klaus]

Correction: The process of making concrete

[zc]

The first picture shows clearly the process of cement manufacture, and there are five stages for manufacturing bags of cement. Crushing the raw materials of limestone and clay into a powder as first stage, and then heating up the mixture properly after a mixing process as second and third stages, in the fourth and last stages, the semi-finished product will be grinded up then packed as bags of cement.

Producing concrete is followed by the second picture. When every material is in a fixed proportion of the amount as 15% cement, 10% water, 25% sand, 50% gravel, and rotating them all to mix by the concrete mixer. The concrete will be ready to be used.

1) Usually in English it is unwise to split the verb and the following object. -> The first picture clearly shows the process.

[Oleg]

zc

-> In the first stage, the raw materials, limestone and clay, are crushed into a powder ....

@Oleg I appreciate your correction, thank you!

The diagrams illustrate the steps and the ingredients for making cement. Furthermore, the used of cement in making concrete for building contruction.

Overall, cement production consist of 5 steps before it wraps in the bags while concerte production only made up by on process.
