Precipitated silica appears as a white, amorphous powder. It has high surface area, porosity, and absorbent properties. Widely used as a reinforcing filler in rubber, it enhances mechanical properties. In the food industry, it serves as an anti-caking agent, and in cosmetics, it functions as a thickening and abrasive agent.

CEMGUARD® Microsilica (Silica Fume) is a by-product of producing silicon metal or ferrosilicon alloys in smelters using electric arc furnaces. It is a grey coloured powder, pozzolanic in nature. It is sourced from a single, dedicated factory in China and produced under strict quality control to maintain the highest levels of product consistency, and ensure minimum standard deviation. In concrete, it fills the space between cement grains - commonly referred to as particle packing or micro-filling. It also reacts with the calcium hydroxide from cement to form an additional binder called calcium silicate hydrate. Both these effects enhance the physical and chemical properties of concrete.
