Portland cement M400 Firuzkuh cement

Cement is a hydraulic binder, in other words, cement is an inorganic powder material, which when mixed with paste water, is absorbed during hydration reactions and processes and even hardened, strengthened and stable even after hardening. Preserves in water. One of the most important synthetic hydraulic cements is Portland cement.

One of the most important synthetic hydraulic cements is Portland cement. Portland cement is a by-product of mixing limestone and clay by a weight ratio of about 3: 1 to 4: 1 (depending on their chemical composition), grinding the mixture in wet or dry ways, homogenizing raw materials, cooking materials In the furnace up to the border of sweating the grains surface and gluing them together in the form of welding or clinker, cooling and grinding the clinker with a bit of gypsum is achieved.

M400 cement, in all reinforced and non-reinforced concrete instruments requiring early resistance compared to the M300, such as columns, ceilings, slab bridges, structures requiring rapid molding, as well as in the air Used cold. It is recommended to use this type of cement due to the high hydration temperature, controlled and used only in places where the sulfate has low destructive effects.
