Raw materials used for Cement Production

Marls are an excellent raw material for cement manufacture, because they contain the lime and the clay component in an already homogenized condition. Calcareous marl of the chemical composition equal to that of Portland cement raw mix, are used for the manufacture of so-called natural cement; however, deposits of such raw materials are not common.

How concrete block is made

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 strength. A typical concrete block weighs 38-43 lb (17.2-19.5 kg).

Why Concrete is The Most Popular Building Material

Raw materials used to make concrete include air, cement, water (to form a paste) and aggregates (sand, gravel, crushed stone). When these are combined a chemical reaction occurs and the paste hardens with rock-like strength. Concrete is malleable whilst wet

Portland cement

Portland cement accounts for more than 95% of all cement produced. To make Portland cement, clay, shale and limestone is ground to a powder and baked in a kiln. The baked mixture forms clods (clinkers), which are then ground up and mixed with gypsum. Most of the raw materials are mined in open pits.
