The high quality concrete, with excellent structural properties, mechanical properties, strong durability, high quality concrete should be used to improve engineering quality, prolong its life span, reduce the comprehensive cost of whole project.As a new type of high performance concrete admixture,  (GGBFS) ground granulated blast furnace slag plant has all kinds of performance advantages about improving concrete compressive resistance, tensile resistance, sheared resistance and bended resistance. 

So, how can we promote concrete building energy-saving while producing high quality concrete? According to Director of famous GGBS Research Center, slag powder, steel slag powder are good concrete admixtures. We mix 10 ~ 35% fine grinding slag powder in the concrete, with 0 ~ 20% ground steel slag powder, 0 ~ 9% silica fume, to replace 10 ~ 50% cement. Total cementitious material consumption is 380 ~ 550 kg/m³ to make C20 ~ C60 Concrete. This technology can manufacture strong characteristic cement, but also turn waste into treasure, and improves the comprehensive utilization of solid waste resources.Great Wall Machinery GGBS production line has been recognized by key customers, the domestic production operation of the production line has been up to more than 30, customers all over the country.

GGBS vertical roller mill is the equipment to grind Ground Granulated Blast furnace Slag (GGBS) into small particles.GGBS (fineness:4200-4500cm2/g) produced by vertical roller mills are being used to substitute clinker in conventional cement manufacturing as well as to partially replace OPC for ready-mixed concrete production, for which the percentage of GGBS usage is typically at 10-15% and 20-25% respectively.

Experts predict that by the end of "The Thirteenth Five Year Plan", high quality concrete mixed with slag powder and other solid waste resources to promote the development of concrete building energy conservation, recycling economy plays a major role.
