Cement and Concrete Production Process Writing Task 1 || WWW.AMANIELTS.IN ||

 

The process details the steps to make cement and then how cement is used as an ingredient in concrete manufacturing. Overall, the process requires initial mixing and chemical transformation of the raw materials clay and limestone, followed by bagging of the finished cement, before it is then combined with other materials to form concrete.

Initially, limestone and clay are collected and crushed together into a fine powder before being placed in a cylindrical mixer. The mixture is then connected to a rotating heater which transforms the powder and it is then ground a second time and sealed in bags as cement.

In order to form concrete, cement is next combined with water, sand, and gravel in a concrete mixer. The proportions for each ingredient are 15% cement, 10% water, 25% sand and finally 50% gravel (which is small stones).
