摘要
文中研究了砂率、粉煤灰和矿渣粉以及石灰石粉的适宜掺量对自密实混凝土工作性能的影响,试验结果表明,胶凝材料用量520 kg/m^(3),掺13.8%的粉煤灰、30%的矿渣粉、8%的石灰石粉,砂率控制在0.53,可以制备出C40免振捣高强自密实混凝土,工程应用效果较好。
The effect of the appropriate amount of sand rate,flour ash and slag powder and limestone powder on the performance of the work performance of self-dense concrete.The test results show that the amount of gel material is 520 kg/m^(3),13.8%fly ash,30%slag powder,and 8%limestone powder were added,the sand rate is controlled at 0.53,which can prepare the C40-free high-strength self-dense and dense concrete,and achieve better engineering applications.
