摘要
研究结果表明,用鲍罗米公式推测轻骨料混凝土28 d抗压强度的误差较大.实测出不同配合比的轻骨料混凝土28 d抗压强度和相应的28 d胶砂试块抗压强度,运用多元线性回归分析的方法完善了鲍罗米公式,所得公式能较准确地预测轻骨料混凝土28 d抗压强度,具有现实指导意义.
Large error exists when using Bowromi formula to speculate 28 d compressive strength of lightweight aggregate concrete.By measuring 28 d compressive strength of lightweight aggregate concrete with various mixing ratios and the corresponding compressive strength of cement block,the Bowromi formula was perfected using multiple linear regression method.The amended formula can forecast 28 d compressive strength of lightweight aggregate concrete more accurately to provide meaningful guidance for practice.
