Portland cement Anti-sulfate Sepahan 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.

Characteristics of anti-sulfate cement:

- Very low permeability

- More efficient due to the absorption of calcium hydroxide by activated slag and smoother slag surface texture

- Excellent chemical resistance to the combined invasion of sulfate and chlorine salts

- Protection and health of reinforcement against corrosion and rust

- Low hydration heat

- Very low concrete expansion at zero and longer bonding in the short run.
