Quick Details
Specifications
Key sepecifaction:
HCSA Cement 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 Cement does release free lime during hydration thus eliminates the major cause of efflorescence.
HCSA cement is manufactured under a strict quality assurance systems GB/T 19001-2000 and GB/T 24001-1996 which accommodates the technical requirements of building chemistry formulators.
Application:
The properties it possessed made it a good adaption to obtain a wide range of products:
l Fast setting cements
l Rapid hardening mortars
l Tile adhesives
l Self-leveling compounds
l Non-shrink grouts
l Water stopping mortars
l etc.
