为了将粉煤灰进行再利用,通过研究粉煤灰的物理和力学特性,并对其掺和的相关材料进行充分的分析对比,最终确定“黏土”作为掺合料能够改善其黏聚力低等缺点,且取材方便、节约成本。同时对用于公路路基填料中的粉煤灰所占的最优比例进行研究,设计并进行了粉煤灰的对比性能试验,确定了粉煤灰在公路路基填料中所占的比例,再进行数据的分析以及施工经济性的合理判断,最终得出用于路基填料时粉煤灰的最佳配合比。
In order to recycle the fly ash, by studying the physical and mechanical properties of fly ash, and fully analyzing and comparing the related materials, the final determination of “clay” as the admixture can improve its cohesion Shortcomings such as low power, and drawing convenient, cost savings. At the same time, the optimal ratio of fly ash used in highway subgrade filler was studied, the comparative performance test of fly ash was designed and carried out, and the proportion of fly ash in highway subgrade filler was determined. Data analysis and construction of a reasonable economic judgments eventually reached the best mixture of fly ash for roadbed filler.
