摘要
通过试验，对常温20℃及100～700℃高温后玻化微珠保温混凝土的抗压强度及劈拉强度进行了比较，研究和分析了不同温度后玻化微珠保温混凝土的抗压强度及劈拉强度的变化规律，并在此基础上建立了高温作用后玻化微珠保温混凝土的抗压强度及劈拉强度的推算公式，可为高温后玻化微珠保温混凝土结构的设计分析提供理论依据。
The compressive strength and tensile strength of glazed hollow bead insulation concrete at 20℃ normal temperature and from 100℃ to 700℃ high temperature are compared by experiment. The changed law of the compressive strength and tensile strength of glazed hollow bead insulation concrete under different temperatures is analyzed. On the basis of the tests and analysis, the calculation formula of the compressive strength and tensile strength of glazed hollow bead insulation concrete is established under high temperatures, which can provide the theoretic basis for the design and analysis of concrete structures.
