There are different types of micro silica fume according to different classification criteria. In terms of supply form, it can be broadly divided into two
Microsilica, or silica fume, is a by-product of the silicon and ferrosilicon alloy production. When these alloys are made, a small amount of silicon dioxide
Fum nedesensificat de silice, Cunoscut și sub numele de fum de silice crudă sau fum primar de silice, is a by-product of the high-temperature smelting of ferrosilicon in industrial electric
Silica Fume or microsilica Silica fume as an amorphous material does not exhibit the long-range order of a crystal. It is a by-product obtained inside
Silica fume is a good concrete admixture, refractory additive, chemical product dispersant and metallurgical pellet binder for its excellent properties of high temperature resistance, prevention
Make high strength concrete (above C70) with silica fume, which can significantly improve the strength and pumping performance of concrete; Make high impermeability (≥ P30),
Ultra-high performance concrete has high compressive strength, high resistance to deformation, high density and other characteristics, mainly because of a variety of mineral admixtures added
Concrete admixtures are added to concrete mixtures to give them certain characteristics that make them more suitable for specific applications. De exemplu, some admixtures can
Blending amount Generally 5-10% of the amount of cementitious materials. The mixing method of silica fume is divided into internal mixing and external mixing. Internal
