Abstract：With physical foaming method,cement,slag,fly ash,lime and gypsum powder as the main material,the high strength and high water storage concrete was prepared.The relationship between fluidity,apparent density,strength,shrinkage,water absorption and frost resistance of high strength and high water storage concrete under 1000 kg/m3,1200 kg/m3,1300kg/m3 and 1400 kg/m3 density levels was studied.The results show that the compression strength of high strength and high water storage concrete is 14.2～33.0MPa,the water absorption of 48 h is 16.2％～27.1％,and the frost resistance is good.It is expected to become a kind of sponge city sidewalk material.
