1. What is the Micro silica fume

Micro silica fume, which is a by-product of producing silicon metal or ferrosilicon alloys.

Micro silica fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Because of its fine particles, large surface area,  and the high SiO2 content, 



2. Densified Micro silica fume Performance in Cement



Densified Micro silica fume can fill the pores of cement particles and generate gel with hydration products and then magnesium oxide reacts with alkaline gel material.



Densified Micro silica fume is used as an admixture for cement-based concrete, mortar, refractory castable. When you mixed the proportion



amount of micro silica in cement-based concrete, mortar, refractory castable, then it can provide you pefect peformance



as following:



A. Significantly increased compression, bending, impermeability, anticorrosive, anti-shock and wearable for cement-based concrete, mortar, refractory castable.



B. With water retention, prevent segregation, bleeding, and significantly reducing the role of concrete pumping resistance



C. Significantly extend the service life of concrete. Especially used in chloride, polluted erosion, sulfate attack, high humidity and other harsh environments, can improve the durability of concrete double or even several times



D. Significantly reduction in jet landing castable concrete and ash, rasie a single spray layer thickness.



E. Is the necessary component of high-strength concrete and have already applied in C**0 cement-based conrete



F. With above five times the efficacy of cement, can improve the durability and lower the cost in ordinary cement concrete castable



G. Effectively prevent the occurrence of concrete alkali aggregate reaction



H. Improve the compactness of cast refractory material. When coexist with Al2O3, more easy to generate mullite phase and enhance its high temperature strength, thermal shock resistance
