通过对不同尺寸和强度等级的粉煤灰混凝土劈裂抗拉强度的试验数据分析,研究粉煤灰混凝土的劈裂抗拉强度与立方体抗压强度的关系,分析粉煤灰以及试块尺寸及形状对强度指标关系的影响。通过与相关试验数据对比及回归分析,提出混凝土劈裂抗拉强度与混凝土立方体抗压强度的换算关系。 Based on the experimental data of splitting tensile strength of fly ash concrete with different size and strength, the relationship between splitting tensile strength and cubic compressive strength of fly ash concrete was studied. The relationship between fly ash, Effect of Shape on Intensity Index. Through the comparison with the related experimental data and regression analysis, the relationship between concrete splitting tensile strength and compressive strength of concrete cubes was proposed.
