摘　　要：通过对EPS轻质混凝土进行配合比试验和抗压强度试验,研究了不同水灰比对EPS轻质混凝土强度的影响。试验结果证明EPS轻质混凝土抗压强度与水灰比值密切相关,水灰比越大,EPS轻质混凝土的强度越低。对试验数据统计分析得出EPS轻质混凝土28d强度与灰水比、EPS掺量及颗粒粒径尺寸之间的关系公式。该强度公式计算值与实测数据值比较,相关性系数为0.99。Based on EPS lightweight concrete mix proportion test and compressive strength test,influence of water cement ratio on compression strength of EPS lightweight concrete was studied.Experimental data showed that the higher the water cement ratio, the lower the compressive strength of EPS lightweight concrete strength.An empirical model was proposed, to take into account water cement ratio, 28 d strength, the packing density and the EPS diameter.Test results were fitted to an empirical model.
