Product Features :
GGBS is one kind of powdery product of superfine milling to water-quenched slag from blast furnace. Its main chemical composition is super activated SiO2AI2O3CaOMgOMnOFe2O3. After it is mixed into the cement concrete as a mixed material, these activated SiO2AI2O3 then can respond to Ca(OH)2 as a result of C3S and C2S hydrate in the cement, further form the hydrated calcium silicate products in order to fill into the cement concrete hole and enhance the cement concrete durability on a large scale, simultaneously transform lower Ca(OH)2 crystals into higher hydrated calcium silicate gelatin, enabling a series of performance on the cement concrete to be remarkably improved.

Application
GGBS as combination project aggregates is widely applies to the road building, the airport construction, the port and harbor construction, the concrete project and so on. Presently overseas GGBS has been mainly utilized to produce higher economic value field, such as the cement, asbestos, aggregate, brick, cast basalt and crystallite glass.

Blast furnaceslag micro-powder, as a
new-type material to mixed with high-performance concerete, has a change
advantages of different performance of concrete, it can substitute the
consumption in various kinds of concrete and cement products equivalently,
greatly change the comprehensive performance of the concrete and cement
products.


Blast furnace slag micro-powder has good
water-retaining property, fine plasticity, little water exudation, good
manipulation nature. Water and hot absorbed slowly, help to prevent risk in the
crack caused by warm rising in large area of concrete. More calcium aluminite
crystal, compensate the shrink caused by too much powder. Harden concrete have
good resistance of sulphate corrode, chlorine salt dialy sising, and seawater
corrode, carbonization, alkali material reaction. Improve the long-term
intensity of hardenning the concrete, have good durability and wearability.
