Csa binder

Описание и отзывы

Характеристики

CSA based cementitious materials is an ideal material for supporting and back-filling
In mining construction, due to its high strength, adjustable setting time, Good fluidity, especially for increasing the output of minerals such as coal and Gold. CSA is also an excellent matrix for making special high performance construction materials such as self-leveling material, grouting material, tile cohesive and repairing Material.

Specifications :

This binder was designed to be blended with Portland cement and anhydrite to make some dry-mixed mortars which need fast setting, rapid hardening, high-strength, freeze resistance, impermeability, corrosion resistance, low pH, low dry shrinkage and micro expansion properties.
