Cement making process/using of concrete - IELTS Academic Writing Task 1

making a concrete and cement

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

The illustrations demonstrate processes of how a cement is made (on the left side) and how a concrete is made.
Limestone and clay, essential materials, are used for a making process of cement.

First of all, a limestone and a clay are crushed into powder, then the powders are put to the mixer and mixed together.
In the next stage, the powder is directly put into large cylindrical rotate heater, then the dry powder is grind to the soft powder - cement.

After all, the cement is packed into bags and is ready to be delivered to customers.

The process of making a concrete is much simpler then cement, only one mechanical device is used - a concrete mixer.
A concrete is mixture of four materials a cement, a water, a sand and a gravel.
The materials are put to the mixer in appropriate ratio. In our case the ratio is following 15% cement, 10% water, one quarter a sand and rest of is a gravel.

RCH, you are taking too many liberties with your report. Remember that the assumption for the Task 1 essay is that you have to report the full procedure to the reader, who will not have any access to the illustrations you were provided with. Therefore, you should be writing an informative essay that does not hold back on representing actual measurements and procedures in the presentation. Doing so means you are delivering incomplete an inaccurate information which can affect your C&C score negatively.

There should have been a transition sentence at the end of the cement creation process that led into the concrete production discussion. Such transition sentences are important when you are reporting on two related procedures. In this case, from cement to concrete since cement is one of the primary requirements for the creation of concrete.

Always indicate the actual measurements needed in the procedure when you are given actual data in the illustration. Estimates such as "a quarter" and "the rest" will only be somewhat acceptable when actual measurements are not involved in the presentation or are merely estimated in the given illustration. The illustration indicates precise measurements which need to be represented in the actual report. Otherwise, the measurement of ingredients in relation to the procedure becomes incomplete. The reader, should he follow your instructions for the creation of concrete will not be able to do so because of the missing measurements for 2 materials in the creation process.

Look out for those tricky past tense words. In this case, the dry powder was "ground" to a soft powder that created cement. In your presentation, you merely said: "soft powder - cement". You need to indicate that the soft powder created is cement. That is not clear in your presentation so the reader doesn't have any idea what cement has to do with the presentation. However, the same style can work for the concrete mixer reference as you explained beforehand that this was a mechanical device used in the process.
