摘　　要：通过拔出试验探讨了变形钢筋与玻化微珠保温混凝土的粘结锚固强度,并与普通承重混凝土进行了比较。试验结果表明,玻化微珠保温混凝土和普通承重混凝土一样,破坏依然以劈裂破坏为主;玻化微珠保温混凝土与变形钢筋的粘结锚固强度稍高于同强度等级的普通承重混凝土;Through pullout tests,the bond strength of deformed bars with glazed hollow bead insulation concrete has been explored,and compared with the test results of common load-bearing concrete. The test results show that similar with ordinary loadbearing concrete, the failure mode of glazed hollow bead insulation concrete is still splitting failure; the bond strength of deformed bars with glazed hollow bead insulation concrete is slightly higher than the ordinary load-bearing concrete of the same strength class; According to the results, we reach the recommendations to improve the bond strength of deformed bars with glazed hollow bead insulation concrete.
