摘要
尾矿料细度较小 (平均粒径为 13 3 μm ) ,对不掺和掺外加剂的二灰稳定尾矿料用作基层、底基层材料的干缩特性进行试验研究 ,从二灰掺量、石灰与粉煤灰比例、外加剂使用、养护管理等角度研究其干缩规律 ,分析了影响混合料的干缩特性因素和干缩机理 。
Shrinkage for WKL stabilized by use of the lime fly ash mixing with mixture or not, which is applied to base and sub base, is systematically tested. In this paper studies its shrinkage law in the quantity of lime fly ash, the use of mixture and maintaining, and analyses the various factors that may influence the shrinkage of mixture and the shrinkage mechanism, which can provides scientific basis for the optimized mixing design and the construction technics.
