摘要：泡沫混凝土（FC）作为一种轻质多孔材料具有优良的保温隔热效果，将其用作建筑保温墙体材料可以有效降低建筑能耗。利用可再分散乳胶粉（RDL）和玻化微珠（GB）改性FC，研究了RDL和GB单独取代以及RDL和GB共同取代快硬硫铝酸盐水泥对FC干密度、抗压强度、导热系数和拉伸黏结强度的影响。结果表明：RDL可以显著提高FC的拉伸黏结强度，GB可以显著降低FC的干密度和导热系数；RDL和GB共同取代水泥时更有利于改善FC的综合性能；RDL和GB总掺量为3%时改善效果最佳，此时FC的干密度为311.7 kg/m3，抗压强度为0.42 MPa，导热系数为0.078 3 W/（m·K），拉伸黏结强度为0.113 9 MPa。 Abstract: As a kind of lightweight porous material, foam concrete(FC) has excellent thermal insulation effect and can be used as building insulation wall material to effectively reduce building energy consumption. Using redispersible latex powder(RDL) and glass beads(GB) to modify FC, and the effect of RDL and GB alone substitution and RDL and GB joint substitution of rapid hardening sulphoaluminate cement on the dry density, compressive strength, thermal conductivity and tensile bond strength of FC were explored. The results show that RDL can significantly improve tensile bond strength of FC, and GB can significantly reduce dry density and thermal conductivity of FC. When RDL and GB replace cement together, it is more conducive to improve the comprehensive performance of FC. The improvement effect is best when the total content of RDL and GB is 3%. At this time, the dry density, compressive strength, thermal conductivity and tensile bond strength of FC are 311.7 kg/m3, 0.42 MPa, 0.078 3 W/(m·K), and 0.113 9 MPa, respectively.
