| Abstract: | Based on the activity of super fine slag powder and fly ash,present the method on confects C80 high performance concrete using P. O42.5R cement and high efficient polycarboxylates water-reducing admixture produced by native. The results of orthogonal experiments contrast indicate that C80 concrete can be confected by adding super fine slag powder which has higher index of activity,and that the concrete has the advantages such as low cost, convenient material acquirement and well durability. |
