PIONEER RICE HUSK ASH has the potential to be used as a substitute silica fumes or micro silica as a much lower cost , without compromising on the quality aspect . Adding PIONEER RICE HUSK ASH to the concrete mix even in low replacement will dramatically enhance the workability , strength and impermeability of concrete mixes , while making the concrete durable to chemical attacks , abrasion and reinforcement corrosion , increasing the compressive strength by 10% - 20 %
