百色水利枢纽工程碾压混凝土配合比试验

RCC mix proportion test for Baise Multipurpose Dam Project

百色水利枢纽工程碾压混凝土配合比试验通过优选材料,缩小配合比试验范围,再用正交设计法进行试验,建立不同材料组合与混凝土抗压强度之间的多元回归方程,根据回归方程计算出混凝土设计配合比,并对计算配合比通过复核试验加以验证,最终确定推荐混凝土配合比。

For the RCC mix proportion test of Baise Multipurpose Dam Project, fine materials were chosen to narrow the testing range, orthogonal design method was applied, multivariate regression equation was established to deduct the relationship between different material combinations and concrete compressive strength. The design concrete mix proportion was calculated with the regression equation and rechecked by test before the final mix proportion was recommended.
