pharmaceutical grade silica is a high performance strength concrete additives. pharmaceutical grade silica is a by product of the ferroally through the arc furnage, gas emissions and air rapid oxidation condensation precipitate formed. It can used in concrete, cemnt,refractory, plastic,rubber, paints,coatings and ceramics ect.
pharmaceutical grade silica 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.
pharmaceutical grade silica increase the compression and abrasion resistance of high-performance concrete and high compactness make concrete against the attack from other chemical elements.
