Detailed Description
HCSA cement 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
Rheology adapt to application
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.
