slag powder concrete slag proces will produce a certain amount of slag, after a long period of accumulation, not only occupy land resources, but also pollute the environment, so the slag treatment has always been a serious problem. With the upgrading of the relevant national technical equipment, the slag has also been a corresponding application, which is turning waste into treasure. Wherein slag can be processed into different fineness slag powder by slag vertical mill , and then applied in many industries, which slag powder in concrete to have a good application.

Slag powder can be substituted with the same amount of cement mixing concrete to improve the workability of fresh concrete, according to the different requirements of concrete, slag powder can be substituted with the same amount of 30-70% of cement per cubic meter of concrete will reduce production costs 15- 30 RMB, other admixtures not achieve this benefit. Further, since the ratio of water demand of slag powder and cement, slag powder can reduce the incorporation of water-cement ratio of concrete, reduce bleeding of concrete water, increase liquidity, improve workability, pumpability, and therefore maintain a good working properties.

Slag vertical mill can process slag into concrete desired particle size of slag powder, and then merging and other materials to complete the production of concrete. Slag vertical mill machine accelerated the application process slag powder in concrete. Currently, Cnaeng slag vertical mill and other mill equipment has also produced a wide range of slag powder, which will be achieved slag powder more value.
