Cement is the most common building material. This material is universal for many types of construction and repair work. Cement is the result of fine grinding of a sintered product of a certain type of clay, marl or mixtures of limestone and clay. Sintering is carried out in specialized furnaces.
Main materials applicable for cement production:
Limestone
Various clays
Gypsum
Various granulated slags (granulated slag)
The main component for the production of cement is yellowish-greenish limestone, also called green limestone, it lies at a depth of up to 10 meters and is well extracted, as it has a soft structure.
The main types of cements:
Portland cement
Slag cements
Alumina cements
Special cements
Portland cement is, according to GOST, a hydraulic binder substance subject to hardening in water and in the open air. The final product of careful fine grinding of fired clinker obtained by sintering the raw mix. The content in such a mixture of calcium silicate is about 75-85%.
Clinker is a semi-finished cement product in the form of granules, obtained by firing and finely ground a mixture of limestone and clay. It is used in the production of cements.
Main clinker minerals:
Alit 50-60%
Alumoferrite 5-15%
Aluminate 5-10%
Ferrite
