本文研究通过圆柱体小芯样剪切试验以及相应龄期的混凝土立方体试件力学性能试验,分别获得了小芯样抗剪强度和立方体试件抗压强度。试验结果表明:小芯样抗剪强度与混凝土立方体试件抗压强度存在显著的相关性;试验所建立的抗剪法测强曲线具有足够的检测精度,能够应用于预拌混凝土抗压强度的现场实体结构检测。研究结果可供工程质量检测与控制参考。
In this paper, the small core sample shear strength and cubic specimen compressive strength were obtained through the small cylinder-like shear test and the mechanical properties test of concrete cubes at corresponding ages. The test results show that there is a significant correlation between the small core-like shear strength and the compressive strength of concrete cubes specimens. The shear strength test curve established by the test has sufficient detection accuracy and can be applied to the compressive strength of ready-mixed concrete Site physical structure testing. The results are available for project quality inspection and control reference.
