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.

 This type of cement, also called ordinary Portland cement, is used for general purposes where no specific specificity of concrete is required. This type of cement is used for construction of sidewalks, road pavements, reinforced concrete bridges, railways, tanks, water pipes and mortars.
