摘要 通过掺加工业废渣型化学激发剂,有效地激发了粉煤灰的活性,大大提高了由粉煤灰、石灰、碎石组成的三渣混合料的早期物理力学性能,并改善了其耐久性,解决了利用三渣作为道路基层材料使用时因其早期强度低而导致施工周期长的关键技术问题,取得了良好的社会经济效益。 The hydration activity of fly ash is effectively activated with adding a kind of activator, which is composed of some industry wastes With this technology, we can improve the early mechanical performances and durability of the mixture material made with fly ash, lime and crushed stone Therefore, the technical key of longer construction periods in using this material as road substrate because its low early strength has been well solved, and good benefits in society and economics has been achieved
