水泥粉煤灰稳定煤矸石级配设计研究

Study on Gradation of Cement-fly Ash Stabilized Coal Gangue

为将水泥粉煤灰稳定煤矸石更好地应用到道路基层,需对其级配进行优化设计。文中以混合料形成骨架密实结构为目标进行粗集料级配设计,以k法为基本理论进行细集料级配设计,最后综合粗集料与水泥粉煤灰砂浆配合比例,提出水泥粉煤灰稳定煤矸石总的级配设计曲线,具有一定的普遍性和实用价值。

of roads, aggregate designed overall For it i gra the better application of cement-fly ash stabilized coal gangue to the base course sneededtooptimize the design of their grading. First, we designed the coarse ding for obtaining mixture formation closegrained skeleton structure, then fine aggregate grading with the basic theory of k law. At last, we made the grading design curves of cement-fly ash stabilized coal gangue through comprehensively comparing the ratioes of coarse aggregate and cement-fly ash mortar. The curves were of certain universality and practical value
