KG powder is a complex mineral superfine powder made by grinding the mix of calcined coal gangue andslag along with fly ash, silica fume in certain proportion. The concrete cement content was reduced by 20% to 40%.Durability related properties include resistance to sulphate attack and acid rain was enhanced greatly. Application ofcomplex mineral superfine powder is an effective way to reduce environment pollution and improve durability ofconcrete under severe conditions.When KG powder mix with concrete, it will increase the durability of concrete with improved pozzolanic reaction andmicro-aggregate filling. As a result of this experimental study, it is noted that the use of 20%, to 40% replacement ofKG powder instead of cement, has significant effect on compressive strength of concrete over time and will withstandsulfate attack and acid rain.
