Cement Concrete

COMPONENETII CONCRETE – CEMENT CONCRETE Cement is a powdered material, such as basic, hydrophilic, chemically unstable. Thixotropic paste mixed with water forms that make plug and harden over time to form “cement stone.” Portland cement (siliceous), a mixture of silicates and calcium aluminates and is obtained by finely grinding Portland cement clinker with the addition of 2 … 7% gypsum to adjust the setting time. Portland cement clinker is produced by burning a mixture of raw materials in rotary kilns. The raw materials used in the manufacture of portland cement clinker are: limestone, marl, clay, leossuri, industrial by-products (slag, ash, shale), additions correction (silica, alumina, ferugionase etc.) casts.
