Sustainable Precast Concrete

The raw material consumption is similar for similar qualities of concrete whether the production takes place in a factory at a ready-mix plant or at a building site. The raw material waste in precast concrete production is very small.

Raw materials for cement manufacturing

The second important raw material for cement production is clay.The main component of clay is formed by hydrous aluminium silicates.The chemical composition of clay may vary from those close to the pure clay to that containing a significant amount of admixtures as iron hydroxide iron sulfide sand calcium carbonate etc. Clay is used as an argillaceous component of raw mix.

Cement manufacturingcomponents of a cement plant

Cement is typically made from limestone and clay or shale. These raw materials are extracted from the quarry crushed to a very fine powder and then blended in the correct proportions. This blended raw material is called the raw feed or kiln feed and is heated in a rotary kiln where it reaches a temperature of about 1400 C to 1500 C.
