Cement properties

Cement is a small powder, which is obtained as a result of the sintering of limestone with some type of clay or its mixture. During the sintering itself, a wide variety of fillers from materials as gypsum, slag, sand and many other components are added to the cement itself. The properties of the so -called “final” product depend on their composition and proportion. The use of a special additive allows you to create salt, fire-and a frost-resistant brand of cement. Cement is widely used in the construction of suburban cottages.

Due to its exceptional binding qualities that allow you to create a high -strength structure, cement is the most popular binder, used in the construction of the building and structure.

Cement labeling will find out which load will withstand hardened cement in some conditions. For example, Mark Cement 400 means that one cub of hardened material, the size of which 10 cm3 can withstand a load of up to 400 kg/cm2 under the press. The most common in construction are brands 400 to 500.

This material is rapidly solidifying, and most brands set together for 30-55 minutes. After 12 hours, the solution completely hardens.
