Concrete: Manufacturing Process, 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 fillerHow concrete block is made, Today, concrete block manufacturing is a highly automated process that can produce up to 2,000 blocks per hour Raw Materials The concrete commonly used to make concrete blocks is a mixture of powdered portland cement, water, sand, and gravel This produces a light gray block with a fine surface texture and a high compressive strength116 Portland Cement Manufacturing, Aug 17, 1971· 116 Portland Cement Manufacturing 1161 Process Description1-7 Portland cement is a fine powder, gray or white in color, that consists of a mixture of hydraulic cement materials comprising primarily calcium silicates, aluminates and aluminoferrit More than 30 raw materials are known to be used in the manufacture of portland cement, and theseEnergy and Cost Analysis of Cement Production Using the ,, about 105 kWh of electricity, depending on the cement variety and process type employed [10] Cement produc- tion spreads across five geo-political zones due to the vast deposit of raw materials (Table 1) Kilns are ma- jorly being fired by the use of heavy fuel oil (LPFO), coal and natural gas However, the dearth of natural gasCement Production, Cement production processes can be categorized as dry, semidry, semiwet, and wet processes depending on the handling of raw material before being fed to the rotary kiln Nowadays, almost all new plants are based on the dry process and many old wet plants are ,.
