Special Grades For Concrete

Through a long history of supplying the steel industry in numerous applications, we can provide technical support and help with innovating new products for the concrete industry.

We Carry
Flyash GGBFS Microcast

MicroCast G is a special grade microsilica the we have innovated. This is mixed with certain proprietary chemicals and GGBFS (Ground Granulated Blast Furnace Slag). This make a super pozzolan and has distinct advantages over standard MicroSilica



Our Microsilica conforms to ASTM 1240 C / 920 D
