Silica Fume(Microsilica)

 

Silica Fume(Microsilica)， They used in concrete. It can improve concrete’s properties such as compressive strength, bond strength, and abrasion resistance; reduces permeability; and therefore helps in protecting reinforcing steel from corrosion. At the same time, silica fume can still be used in the production of refractory and porcelain; to raise intensity and durability, it also can be used in paint, coating, resin, rubber and other high molecular as a filler material to improve the material overall performance.
GGBS/GGBFS

Ground Granulated Blast Furnace Slag(GGBFS)

GGBS/GGBFS(standard BS:6699) is a fine powder that is used in concrete as a 'cement'. The major use is in ready-mixed concrete. In the production of ready-mixed concrete, GGBS replaces a substantial portion of the normal Portland cement content, generally about 50%, but sometimes up to 70%. The higher the proportion, the better is the durability. GGBS is also used in other forms of concrete, including site-batched and precast.
 
In the production of ready-mixed concrete, GGBS replaces a substantial portion of the normal Portland cement content, generally about 50%, but sometimes up to 70% or more. The higher the proportion, the better the durability. The disadvantage of the higher replacement level is that early-age strength development is somewhat slower.
 
GGBS is also used in other forms of concrete, including site-batched and precast. Unfortunately, it is not available for smaller-scale concrete production because it can only be economically supplied in bulk. GGBS is not only used in concrete: other applications include the in-situ stabilisation of soil.
