碾压混凝土强度特性的研究
Research on strength of roller compacted concrete
【摘要】 本文对碾压混凝土的抗压强度、抗拉强度及本体抗剪强度这三个最重要的力学性能进行深入研究,目的是为现有的理论提供可靠的依据。根据中国碾压混凝土工程的大量试验数据,用相关分析的方法回归8个方程,包括抗压强度与灰水比及粉煤灰掺量、抗压强度增长率与龄期、劈裂抗拉(轴心抗拉)强度增长率与龄期、劈裂抗拉(轴心抗拉)强度与抗压强度、轴心抗拉强度与劈裂抗拉强度和抗剪断参数与龄期的关系。
【Abstract】 The aim of this paper is to provide the credible evidence for existing theory.Compressive strength(Rc)、splitting tensile strength(Rpl)、axis tensile strength(Rl) and body shear strength of roller compacted concrete(RCC) are investigated.According to the many experimental data of Chinese RCC projects,eight regressive equations are set up by using the method of correlation analysis,including following relations between Rc and the ratio of cementitious quantity to water quantity and content of fly ash,between increasing rate of Rc and age,between increasing rate of Rpl (or Rl) and age,between Rpl(or Rl) and Rc,between Rpl and Rl,and between body shear strength and age.
