MicroSilica Introduction

Microsilica has historically been considered a waste product. However, from the mid of 1970s, microsilica has discovered as

a new-style special materials, which can be used in a variety of productive ways. Microsilica increases the compression

and abrasion resistance of high-performance concrete and high compactness make concrete against the attack from

other chemical elements. In the refractoryindustry, microsilica increases high temperature strength and thermal

conductivity in castables.
