Double Fast High Belite CSA Cement
These are hydraulic binders (referred to as high strength double-fast cement) with high strength, fast setting and rapid hardening properties, made from fast setting rapid hardening high belite sulpho aluminate cement clinker, moderate amount of gypsum (or industrial by-product gypsum), slag, prescribed mixing amount of fly ash and steel slag with fine grinding.
Note: the mixing amount of fly ash and steel slag shall not be less than 12% and more than 30% of cement mass. Among which, steel slag shall not be more than 9% of cement mass.

Strength Data:

Advantages:
-
Fast setting, rapid hardening, high strength.
-
Micro expansion, low dry shrinkage, the length change is very small. Dry shrinkage rate is just 1/8 of Portland cement.
-
Have very good anti-corrosion property in sulfate, chloride, magnesium salt and seawater. Corrosion resistance coefficient >1.
-
High impermeability, permeation height is 1/5 Portland cement.
-
High frozen resistance property can get the strength of critical intensity of cold in 2h.
-
Low hydration heat release.
-
PH value is under 10.0 for Glass fiber reinforced concrete (GRC) products.
-
Can be mixed with Portland cement in a proper ratio to make a low shrinkage.
Application Area:
-
Glass fiber reinforced concrete (GRC)
-
Precast products
-
Building reinforcement
-
HPC and RPC
-
Rush projects and construction, projects in winter
-
Foam concrete
-
High early strength non-shrinkage grouts
-
Waterproof and leak stopping materials
-
Shot-concreting project
-
Conventional concrete
