| 摘 要： | 与普通二灰碎石施工工艺相比，碱性激发提高二灰碎石强度的关键在于硫酸钠的化学特性，它能极大地提高二灰碎石的强度，几乎与水泥稳定碎石相当，而且在获得高强度的同时也能降低施工成本，是一个值得推广的新工艺。

| Abstract: | Compared with the construction technique of common lime-fly ash aggregate, the key of basic excitation＇s improving lime-fly ash aggregate lies in the chemical property of Na2SO4. It can improve greatly the strength of lime-fly ash aggregate which can be equivalent to that of cementstabilizing aggregate. Meanwhile it can reduce the cost and worthy of popularization. |
