| Abstract: | In this paper,mix ratio of self-compacting and high performance concrete is designed by using the modified overall calculation method.On the basis of mix ratio design,workabilities and mechanical properties of self- compacting concrete are discussed based on cement,fly-ash,fine and coarse aggregation,and admixtures by the method of orthogonal experiment.The optimized mix ratio of self-compacting concrete is determined by mathematic means.It shows that the modified overall calculation method is more scientific and rational and exact on mix ratio design of self-compacting concrete. |
