摘要
使用巴丹吉林沙漠的风积砂替代部分河砂配制混凝土,在正交试验的基础上分析使混凝土抗压强度达到最优的因素水平组合。分析风积砂替代河砂的比率对混凝土的抗压强度的影响,初步推断,使用风积砂配制C50高强混凝土其最佳替代率在0~40%范围内能够使混凝土达到最佳力学性能。
Using the aeolian sand in Badain Jaran Desert instead part of the river sand to prepare concrete,on the basis of the orthogonal test conduct analysis of the factors combination make concrete compressive strength to achieve the optimum. Analyzed the influence of aeolian sand instead river sand ratio on concrete compressive strength,preliminary inference,the best replacement rate of using aeolian sand to prepare C50 high strength concrete within 0 ~ 40% can make concrete to achieve the best mechanical properties.
