FEATURES:
Greater resistance to sulphate attack, it prevents from Alkali aggregates reaction due to low Alkali content. Dark color produce better compatibility. Due to higher fineness better finished product is produced and it is economically cost effective.
Strength development:
The strength development of Falcon brand SRC is primarily dependent on the water/cement ratio. In this regard to achieve the highest strength good quality Sand, Crush & Tap water is recommended.
Curing:
Good curing significantly improves the compressive strength of concrete and minimizes the shrinkage cracks. Curing also improves quality of concrete surface, it reduces permeability thereby reducing the carbonation rate of concrete.
USAGE:
Falcon Brand Sulphate Resistant Cement is specially used in sea and coastal areas. Greater resistance to chemical attack from sulphates and dissolved salts present in sea and saline waters.
