· The appliions of steel slag powder and steel slag aggregate in ultrahigh performance concrete (UHPC) were investigated by determining the fluidity, nonevaporable water content, and pore structure of paste and the compressive strength of concrete and by observing the morphologies of hardened paste and the concrete fracture surface. The results .
Grain Slag Powder Processing Technological Process. Phase one: raw material crushing Grain Slag blocks will be crushed to 15mm50mm fineness by crusher. Phase two: grinding Grain Slag material will be sent to the storage hopper by the elevator, and than the feeder will send the material to the main mill for grinding.
