Quick Details
Specifications
Key specifications:
HCSA cement clinker is a hydrautic binder based on calcium sulphoaluminate.Its main raw mineral consitituent is C4A3_calcium sulphoaluminate and dicalcium silicate.Besides,it has more excellent properties than those calcium aluminate cement and calcium silicate portland cement.
Porperties:
Incorporation with csa cement into a variety of mix design,csa cement produce exhibit a rang of properties:
Rapid set
Adjustable setting time
High early strength
Increased strength in time
Low shrinkage
Micro expansion
Low alkanity
Sulphate resistance
Low CO2 emission
ect.
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.
