Product Description

General characteristics
HCSA BINDER is a hydraulic binder based on calcium sulphoaluminate, rather than calcium aluminates which are the basis of Calcium Aluminates 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.
HCSA Binder is manufactured under a strict quality assurance systems GB/T 19001-2000 (I. E. ISO9001: 2000) and GB/T 24001-1996 (I. E. ISO 14001: 1996)) which accommodates the technical requirements of building chemistry formulators

HCSA Binder is normally supplied in one-ton bag which include a moister resistant barrier. However, in common with all hydraulic binders HCSA Binder must be kept from moisture, and can retain its properties for up to six months when properly stored.

The properties of HCSA Binder conform to the standards of the manufacturer and to the Chinese relevant standards.
