Sep 01, 2015· The processes involved in the manufacturing of the concrete blocks are as follows: Selection and proportion of Ingredients: The main criteria for the selection of the ingredients are the desired strength of the block. The greater the proportion of coarse aggregate, the greater will be the strength of the quantity of cement used.
The cement manufacturing process starts from the mining of raw materials that are used in cement manufacturing, mainly limestone and clays. A limestone quarry is inside the plant area and a clays quarry is as far from the plant area as 25 km.
Concrete: Manufacturing Process . A good quality concrete is essentially a homogeneous mixture of cement, coarse and fine aggregates and water which consolidates into a hard mass due to chemical action between the cement and water. Each of the four constituents has a specific function. The coarser aggregate acts as a filler.
