Silica fume can be used as a cement replacement to improve the properties of concrete. Since silica fume is collected from smelting silicon or manufacturing ferrosilicon alloys, its formation undergoes changes among three states of matter. ...
The effect of silica fume on refractory castables Silica fume consists of ultra-fine spherical particles that can fill the pores among the particles of the castables. So the water consumption and porosity of the castables are both reduced. ...
Mass concrete is characterized by thick structure, large size, large pouring volume, long construction time, and high construction process requirements. The construction of mass concrete is relatively difficult, and cracking is easy to occu...
About silica fume Silica fume is amorphous, powdered byproduct obtained from the smelting process of ferrosilicon, industrial silicon by a baghouse. The average particle size of silica fume is 0.1-0.15 μm, which is a few percent of the ave...
