Blast furnace slag 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 comprehen siveper formance of the concrete and cement products.
Balast 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, alk ali material reaction. Improve the long-term intensity of hardenning the concrete, have good durability and wearability.
