Green High Performance Concrete (GHPC) represents the development orientation of world concrete industry. Addition into concrete of mixture (slag powder, fly ash etc) improves concrete workability greatly. There are many technologies for producing finely ground slag powder, but they are not so dieal. Therfore, study and development should be intensified. Shougang is strong in comprehensive utilization of slag. Comprehensive utilization of industrial waste slag will be intensified in order to meet requirement of producing "zero pollution green industrial no-waste product".
