IELTS: 'right proportion of raw materials'; Cement and Concrete production

The diagram below shows the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes

===============================================

The first diagram illustrates the tools, the material, and the step of making cement while the second diagram describes the proportion of cement and any other material to produce concrete.

Overall, cement produced passes 4 steps before being ready to package. In term of making concrete, all material are mixed in one tool, called concrete mixer or molen.

As per the first diagram, producing cement process is begun with powdering and mixing raw material, limestone and clay using crusher then mixer. After that, the mixed material is processed through rotating heater in order to melt it. Cement then is ready to be packaged after grinded in advance.

The quality of the concrete is determined by the right proportion of its raw material. Fifteen percent cement, 25 % sand, small stone 50% are blended in one place, namely concrete mixer. Such equipment works to mix all material given while flowing some water (approximately 10%). Spinning process inside this tool ensures the right proprtion of combination mixed well.

Your details paras are pretty good :)

Yes of course.... Here it should be always the diagram and not graph or chart. There are six types of essays for this task;
1. Line graphs
2. Bar charts
3. Pie charts
4. Table
5. Flow chart
6. Diagrams (like this task)
There can be combination of these two - e.g. Line graph +bar chart

Very nice work... good detailing ..
