The original micro silica fume is produced by the condensation of gas and dust released by metal silicon at high temperature. It has the characteristics of large specific surface, high activity and strong micro aggregate. Because of its low accumulation density, about 200 kilograms per cubic meter, the volume of undensified silica fume is larger than that of the same weight, and there is a certain increase in transportation cost. But the original micro silica in the use is more convenient, because of small particles, easy to disperse, basically do not increase the concrete mixing time, has increased the density of concrete, increase strength, water resistance, good filling effect and superplasticizer good adaptability etc. The color of the original silica fume will be lighter than the densified silica fume, so it will not deepen the color of the concrete.
Henan Superior Abrasives I/E Co., Ltd is one of the largest Silica Fume Suppliers in China, our factory can produce densified silica fume and undensified silica fume.
Undensified Silica Fume Bulk density (320-360 kg/m3)
