摘要
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 test data analysis of splitting tensile strergth of fly ash concrete with different sizes and strength grades,the relationships between fly ash concrete splitting tensile strength and cubic compressive strength were studied.The effects of fly ash,specimen size,specimen shape on the strength index were also analyzed.By comparing with related experimental data and regression analysis,the conversion relationship between concrete cubic splitting tensile strength and cubic compressive strength was proposed.
