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.
Sample Response
The diagrams showillustrate the process of making cement and howmaking cement, and how concrete is produced from cement for construction purposes.
Overall, Deleteit is clear from the diagrams that there are five main stages in the production of cement. By contrastMeanwhile, only one mixing steponly two steps are required to produce concrete.
In the first step of cement productionAt the first step of the cement production, limestone and clay are crushed into powder. The process continues as this powder is mixedcontinues with mixing this powder in a machine called a mixercalled mixer. The powder is then passed through the rotating heatermoved to the rotating heater where it is heated to a high temperatureto high temperature. The next step is the material being ground and becoming cement. InAt the final stage, cement is packedpackaged into bags and is ready to be used to produce concreteand ready to produce concrete.
The first step in the process of making concrete is mixing cement, water, sand and gravel in the proportionsproportion of 15%, 10%, 25% and 50%, respectively50% respectively. This mixture is then put into a concrete mixer to produce concrete, which is used for building purposes.
Why this response received Band 7.0
The response covers both diagrams accurately and presents the cement sequence and concrete proportions in a clear, logical order. Its main limitation is an imprecise overview stating that concrete requires two steps, alongside several awkward grammatical constructions. The highest-priority improvement is to describe concrete production as a single mixing stage and refine articles, prepositions, and passive structures throughout.
IELTS Writing Criteria Scores
Task Achievement
The principal cement stages, equipment, and all four concrete ingredients and proportions are reported accurately.
Describe concrete production in the overview as one mixing stage and make the contrast between the multi-stage and single-stage processes exact.
Coherence and Cohesion
The response follows the visual sequence logically and separates the two production processes into focused paragraphs.
Link adjacent cement stages more smoothly while avoiding formulaic sequencing phrases such as repeated references to 'the step'.
Lexical Resource
The response uses an appropriate range of process vocabulary, including terms for crushing, heating, grinding, packaging, and mixing.
Improve collocational precision with forms such as 'in a mixer', 'at a high temperature', and 'in the proportions shown'.
Grammatical Range and Accuracy
Simple and complex structures communicate the process clearly, but article, preposition, and passive-construction errors recur.
Review noun phrases and passive coordination, especially where an article is required before equipment names or temperatures.
