MICRO SILICA FUME WITH POZZOLAN

Description

ORISIL SILICA FUME is an extremely fine material, with an average diameter **0 times finer than cement. At a typical dosage of 8% by weight of cement, approximately **0,**0 particles for each grain of cement will fill the water spaces in fresh concrete. This eliminates bleed and the weak transition zone between aggregate and paste found in normal concrete. This micro filler effect greatly reduces permeability and improves paste-to aggregate bond in ORISIL SILICA FUME concrete compared to conventional concrete.The ORISIL SILICA FUME reacts rapidly providing high early strength and durability. The efficiency of ORISIL SILICA FUME is **5 times that of OPC and consequently concrete performance can be improved drastically.
