摘要
采用正交试验研究了二灰稳定再生集料的配比,对二灰稳定再生集料正交试验方案的最大干密度、最佳含水量以及不同龄期的抗压强度进行了研究,考察了细集料掺量、粉煤灰和石灰的用量对混合料强度的影响,得出了性能优化的配合比,并提出了工程应用的建议。
Orthogonal experimentation were used to optimize the proportion of aggregate stabilized with lime and fly-ash. The optimum moisture content, the maximum dry density and the compressive strength in various ages were tested, the influence of fine aggregate content, the amount of fly ash and lime on the strength of mixtures were analyzed. The optimized proportion of ASLF mixture was obtained, some suggestions were made for engineering applications.
