摘要
采用室内试验,对免振捣多孔混凝土排水基层的力学特性进行研究。研究发现,其7d抗压强度与28d抗压强度具有良好的线性关系,其28d劈裂强度与90d劈裂强度具有良好的对数关系;其劈裂强度与抗压强度具有良好的幂指数关系,其弯拉强度与抗压强度具有良好的幂指数关系。结果表明,可以采用短期强度预估长期强度,可以测定劈裂强度或抗压预估弯拉强度。
In this paper, mechanical properties of permeable base of vibration-free porous concrete are studied by indoor test. Some relations are founded that 7 days compressive strength has a good linear relationship with 28 days compressive strength; the splitting strength of 28 days has a logarithmic rela- tionships with splitting strength of 90 days; the splitting tensile strength and compressive strength have exponential relationships; the flexural tensile strength and compression strength have exponential rela- tionships. The results show that short-term strength can he used to estimate long-term strength and de- termine splitting strength and compressive flexural tensile strength.
