小直径芯样混凝土力学性能指标间的换算关系研究

Study on the relationship between the mechanical properties of concrete by small diameter core samples

本文以直径44mm芯样试件及标准立方体试件为研究对象,研究小芯样混凝土力学性能与标准立方体试件抗压强度以及小芯样混凝土力学性能间的相关关系。研究结果表明,直径44mm芯样混凝土的抗拉强度、抗折强度、双剪强度以及单剪强度间存在较好的相关关系,同时小芯样混凝土抗拉强度、抗折强度、双剪强度以及单剪强度与立方体试件抗压强度亦存在良好的相关关系。

The relationship between the mechanical properties of small core concrete and the compressive strength of standard Cube Specimens and the mechanical properties of small core samples were studied by using the diameter 44 mm core sample and the standard cube specimen as the research objects. The results show that the tensile strength, the diameter of 44 mm core concrete flexural strength, shear strength and shear double well correlated strength, while the small cores of the tensile strength of concrete and concrete flexural strength, shear strength and shear strength of single double cube and also there is a good correlation between the compressive strength.The research results can be used for structural concrete strength detection and control reference.
