Salt Resistant Cement

المواصفات الفنيه

Definition:

It is an Portland Cement with moderate resisting sulfates properties that hardens into solid a mass when combined with water.

It is resulted from pulverizing and softening of clinker formed by burning a mixture of homogenized limy materials and clay materials

which contain proportionate rates of Silica, Alumina, Sulfur Oxides, and adding gypsum during pulverizing.

Usage :

In construction fields that require a moderate sulfates resistance with less thermal emission at mixing process.​
