In order to meet demand of anti-seepage in National Gymnasium basement,large area steel-slag mixtures were backfilled,which recycles industrial solid waste, and creates social benefits and economic benefits.

Described in this paper are the features, mix ratio, strength test, construction process and the key points in construction for modified three constituent mixture of waste plaster.

This paper studies and analyses the influence of the distribution of the steel slag radius on the mechanical properties of steel slag concrete, as well as the best relation of gradation by test.

5 of cement, strength of steel slag concrete is slightly decreased,but its fluidity is improved.

Through imitation analysis of three kinds of walls(clay brick wall,steel slag concrete wall,abated concrete wall) and we can draw a conclusion that the heat preservation and storage ca.
