HCSA BINDER is a hydraulic binder based on calcium sulphoaluminate, rather than calciumaluminates which are the basis of CALCIUM ALUMINATE CEMENT or calcium silicates which
are the basis of PORTLAND CEMENT. The difference gives HCSA BINDER properties
particularly suited to formulators of products such as self-leveling or self-smoothing compounds,
rapid hardening screeds, tile adhesives, non-shrink grouts, rapid setting and special mortars.
HCSA BINDER is used in formulated products either as a hydraulic binder by itself or with the
addition of calcium sulphates, or in combination with PORTLAND cement. The setting time is
quicker than that of PORTLAND cement, and it also has a rapid strength development. HCSA
BINDER does not release free lime during hydration thus eliminates the major cause of
efflorescence.
