摘要
机制砂替代河砂应用于各强度等级混凝土的实际生产中,可以有效解决天然河砂资源匮乏地区优质细集料的供应难题。结合山西运城地区机制砂的特点,通过试验研究不同石粉含量(4%,6%,8%和12%)对C55机制砂混凝土的工作性能和各龄期抗压强度的影响规律。研究结果表明:石粉含量对C55机制砂混凝土的工作性能和力学性能都有显著的影响。
The mechanism of sand replacement river sand application in the actual production of each grade of coagulation, can effectively solve the natural division sand capital and the lack of the southern view aggregate supply problem. Combined with the characteristics of the meehanism play in Yuneheng district of Shanxi Province, the study results show that the performance of the different stone powder contained in the 50ESNCR and the law of the famous period resisting Zhuang＇ s intensity are studied, and the result shows that the content of the stone research has significant influence on the working and mechanical properties of the volume soil.
