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.


Here is my essay. Can you correct it for me? Thanks a bunch. Emotion: smile

The two pictures illustrate how cement is produced and used in the production of concrete. As can be seen clearly, there are several steps in cement production, while concrete seems to be produced easily.

Looking at the first diagram, to produce cement, limestone and clay are crushed into powder before being poured into a mixer. The mixture then is heated by a rotating heater. The next important stage of cement making process is that the heated mixture of limestone and clay is ground. Afterwards, it is packed into bags, ending the cement production.

In concrete production, there are four main materials, including cement, water, sand and gravel mixed with the percentages of 15%, 10%, 25% and 50% respectively. After being mixed for a while, concrete is ready for building purposes. According to two diagrams, making concrete seems to be simpler than producing cement, and it does not have the involvement of heat.

IELTS Task 1 requires that you describe the chart, graph, map or diagram without drawing conclusions or stating an opinion. Suggestion: Cement production requires crushing, mixing, heating, grinding and bagging; whereas concrete production requires only mixing. )

Looking at the first diagram, t To produce cement, limestone and clay are crushed into powder before being poured into a mixer. The mixture then is heated by a rotating heater. The next important stage of (missing word) cement making process is that the heated mixture of limestone and clay is ground. Afterwards, it is packed into bags, ending the cement production. (Suggestion: Then the heated mixture of limestone and clay is run through a grinder, producing cement. The last step in the process is packing the cement into bags.)

After being mixed for a while, (missing word) concrete is ready for building purposes. According to two diagrams, making concrete seems to be simpler than producing cement, and it does not have the involvement of heat. Unlike cement production, no heating or grinding is required to produce concrete. (This is not a conclusion or opinion; it is a factual observation.)
