Cement Grade in China Csa Cement(72.5)

CSA binder is a hydraulic binder based on anhydrous calcium sulphoaluminate cement. 
It has excellent properties like high early strength, fast set, rapid hardening, anti-sulphate, waterproofing, anti-freeze, low dry shrinkage, micro expansive etc. 
Not noly has good adaption to chemical additive, but also has good improvement when mix with portland cement and other mineral products. When mix with portland cement, it can make the mixture has adjustable setting time, good fluidity,high ealry strength etc.
It is a good raw material to suit for mortar formulation like tile adhesive,non-shrink grouting material, concrete repairs,self-leveling compounds, grc products, rapid hardening mortar etc.

Product Feature
1.High early strength and bond strength.1d compressive strength is 50mpa, 7d compressive strength above 75mpa.
2.adjustable setting time, its initial set time is 10min, final set time is 350min, when mix with portland cement or other mineral products, the setting time can be adjusted to customers' requirement.
3. good fluidity, which is important item to mortar products
4.good adaption to chemical additive like deformer,ploymer, retarder, accelerator, sodium sitrate etc.
3.Water resistance strength and freezing-thaw resistance strength are better than Portland cement.
4.high fineness, its surface specific area is above 350m2/kg, thin enough to make waterproof products.
