摘　　要：为了研究钢渣-粉煤灰泡沫混凝土的各种性质,通过实验对比研究泡沫混凝土抗压强度与孔隙率的关系模型,观察分析泡沫混凝土内部结构。结果表明,泡沫混凝土抗压强度与孔隙率呈指数关系,在相同孔隙率的条件下通过增大气孔孔径可以提高泡沫混凝土抗压强度。钢渣-粉煤灰泡沫混凝土的导热系数较低,500-900 kg/m^3导热系数范围为0.113-0.153 W/（m·K）。In order to study a variety of properties of concrete foamed by steel slag and fly ash,the models predicting foamed concrete compressive strength and porosity were also investigated,and the internal structure of foamed concrete was analyzed through experiments. Results show that the foam concrete compressive strength is exponential to its porosity. With the same porosity,the compressive strength of foam concrete can be improved by increasing stomata aperture. The coefficient of thermal conductivity of the concrete formed by steel slag and fly ash is low,500 - 900 kg / m^3,and the coefficient of thermal conductivity rang is 0. 113 -0. 113 W /（ m·K）.
