s a new type of high performance concrete admixture, slag powder has all kinds of performance advantages about improving concrete compressive resistance, tensile resistance, sheared resistance and bended resistance. At present, with the same amount of slag powder instead of concrete and cement product of cement dosage, which has become the main trend of building materials industry.

Ground Granulated Blast Furnace Slag (GGBS). GGBS is a by-product slag material from the iron and steel industry, which substitutes cement to significantly reduce the carbon content per tonne of concrete products.

A fine powder by-product that can replace a proportion of cement within concrete mixes. GGBS provides better workability, making placing and compacting easier. With considerable sustainabilty benefits, GGSB also lowers early-age temperature rise, reducing the risk of thermal cracking in large pours.

In addition to the environmental advantage, concretes incorporating slag have greatly enhanced chemical resistance particularly to chlorides and sulfates and are especially advantageous in a marine environment, resistance to Alkali Silica Reaction (ASR) is also enhanced.

The GGBS grinding mill,ggbs ball mill is supplied by Clirik machinery , The Clirik machinery is a professional supplier of ggbs powder production line, can provide "turnkey" service from civil engineering to debugging and capacity and standard reaching to customers, let customers put into production of mineral powder with saving worry, saving effort and high-efficiency.
