sulphoaluminate cement

Product Description

CSA BINDER is not a cement, some of clients called it csa additive, it`s a pure csa clinker, the precursor to csa based cements. This binder is a hydraulic, cementitious mineral blend, high in C4A3S-(Calcium Sulfo aluminate crystals) compound. Upon mixing with Portland cement and gypsum components, it yields a very early and strong cementitious matrix.

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.

This CSA qualities of fast setting and high early strength development are not related to CAC (high alumina cement), even though the Aluminum Oxide content is high. CAC is a refractory cement with a completely different microscopic crystal structure.

When blended with Portland cement, CSA functions as a catalyst in the rapid hardening process or concrete, and the more CSA that is used, the higher the early strength. However, higher replacement dosages will significantly reduce the set time. All csa are inherently fast setting. In order to boost the working time, chemical retarders and accelerator are often used.

This CSA BINDER is specially produced for Dry-mixed mortars and artificial Stone by our Polar Bear plant in year ***0.
