摘要
通过对217组混凝土抗压强度数据进行数理统计回归分析,得出高强混凝土fcu,15,fcu,10相关系数大于0.90,相关性好;并在此基础上得到尺寸换算系数:C60的尺寸换算系数fcu,15/fcu,10为0.94,C70~C100的尺寸换算系数fcu,15/fcu,10为0.91。研究结果可用于高强混凝土的实际应用指导,并为相关标准编制者提供有力的理论依据。
The correlation coefficients between fcu,15, and fcu,10 of high-strength concrete was good, more than 0.90, which was obtained by the mathematical statistics regression analysis with 217 compressive strengths of concrete. And on this basis, the fcu,15, / fcu,10 size conversion factor of high-strength concrete was also derived : the C60 concrete was 0.94, the C70-C100 concrete was 0.91. The results can be used for the practical application guidance of high-strength concrete, and provide an adequate theoretical basis for related standard preparers.
