29.05.2010The majority of precast concrete plants today employ bulk cement in their operations. Bulk cement is stored in circular or square silos made of concrete or steel. Given that cement is sensitive to moisture and must remain dry until used, the silos must be watertight. If kept dry, cement will retain its quality for a very long time.

16.11.2022The raw materials were characterized, and the physical and mechanical properties of the modified cement pastes were studied, as well as their resistance to a short-term thermal shock at 250 C. The study was supplemented by intelligent modelling of compressive strength using the support vector machine (SVM) algorithms.

Raw materials Composition Portland cement consists essentially of compounds of lime ( calcium oxide, CaO) mixed with silica (silicon dioxide, SiO 2) and alumina (aluminum oxide, Al 2 O 3 ). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

The most of the alkalies present in raw materials are carried away by the Hue gases during heating and the cement contains only a small amount of alkalies. If they are in excess in cement, they cause a number of troubles such as alkali-aggregate reaction, efflorescence and staining when used in concrete, brickwork or masonry mortar.

The material is then heated to temperature of nearly 1400C to 1500C when it gets fused together. The fused product is known as the clinkers or raw cement. The size of clinkers varies from 3 mm to 20 mm and they are very hot when they come out of burning zone of kiln. The clinker temperature at the outlet of kiln is nearly 1000C.
