1. BS-HFR CEMENT
(High Strength Fast Setting Rapid Hardening High Belite Sulphur Aluminate Cement)
The cement made by grinding High Strength Fast Setting Rapid Hardening High Belite Sulphur
Aluminate cement clinker, gypsum, slag and fly ash together. This cement is a hydraulic material
which have fast setting rapid hardening properties. Code No. is BS-HFR.

Advantages:
1/ Fast setting, Rapid hardening, high strength; 4h compressive strength can reach 18Mpa,
75Mpa after 28d.
2/ Micro expansion, low dry shrinkage, the length change is very small. Dry shrinkage rate is just
1/8 of Portland cement.
3/ Have very good anti-corrosion property in sulfate, chloride, magnesium salt and seawater.
Corrosion resistance coefficient >1.
4/ High impermeability, permeation height is 1/5 of Portland cement.
5/ High frozen resistance property, can get the strength of critical intensity of cold in 2h.
6/ Low hydration heat release
7/ PH value is under 10.0 for GRC products.
8/ Can be mixed with Portland cement in a proper ratio to make a low shrinkage.
Application Area:
1/GRC
2/Precast products
3/Building Reinforcement
4/ HPC and RPC
5/ Rush projects and constructions, projects in winter.
6/ Foam concrete
7/ High early strength Non-shrinkage grouts
8/ Waterproof and leak stopping materials.
9/ Shotcreting projects
10/ Conventional concrete
