Abstract
In this paper,the raw material parameters and test data of self-compacting concrete are introduced,and the mix ratio is designed and calculated.Among them,the water is 177 kg/m3,the cement is 281 kg/m3,the machine-made sand is 811 kg/m3,the gravel is 848 kg/m3,the fly ash is 141 kg/m3,the mineral powder is 47 kg/m3,the admixture is 11.26 kg/m3,the water-binder ratio is 0.38 kg/m3,and the sand rate is 49%.Using this mix ratio to make self-compacting concrete can better meet the material properties,thus improving the overall con-struction quality.关键词
