IELTS Writing Task 1 [5] The two diagrams represent the production process of cement and the subsequent production of concrete used for building purposes. The production of cement is divided in three main parts: the crush and mix of basic materials, the heat and finally the grind. The concrete production is less complex and consists of mix different materials. The cement production begins with limestone and clay passing through a clusher. Then the powder generated in this step is put into a mixer and, after it, lead through a pipe to a rotating heater that is maintained by an external source of heat. The mix obtained pass through a grinder in order to become the cement we know. This final product then is put into bags. The concrete production is simpler and doesn’t involve neither heat nor different steps. It consists in mix materials. The quantity of each material is well definite: half of it must be composed by small stones (gravel), while the other half is divided in 25% of concrete, 10% of water and, finally, 15% of concrete. All these substances are put into a concrete mixer that rotates until the concrete become ready to be used.

The concrete production production of concrete is simpler and doesn’t involves neither heat nor different a series of separate steps. It consists in of a mix of materials. The quantity of each material is well definite defined:; half of it must be composed by of small stones known as (gravel), while the other half is divided in comprised by 25% of concrete, 10% of water and, finally,15% of concrete. All these substances/materials are put into a concrete mixer that rotates until the concrete becomes ready to be used for use.
