Production Of Concrete

IELTS Task 1 Process- Cement and Concrete Production

IELTS Task 1 Process- Cement and Concrete Production

The production of cement has 5 stages, it commence with the mixing of two raw materials and completing in the packaging a new cement. Concrete production has a simpler process by mixing the four elements (Cement, water, sand and gravel) in the concrete mixer. It starts with Limestone and clay is crushed together, resulting in powder is then mixed.
