电石渣与粉煤灰稳定基层试验及强度影响因素

Test on Calcium Carbide Waste & Fly Ash Stabilized Gravel Base and Influencing Factors of Its Strength

利用电石渣和粉煤灰作为原材料,通过开展一系列室内实验,在确定混合料中二灰所占比例基础上,主要讨论了影响二灰稳定砂砾强度的各种因素。这些因素包括养护龄期、养护温度、压实度、土的级配和最大粒径、劈裂强度和延时时间等。

By using calcium carbide waste and fly ash as raw materials, a series of indoor experiment was carried out to oonfirm the best propertion of these two ashes in mix. Then, all kinds of factors having influence on the strength of stabilized gravel were discussed. These factors include curing age, curing temperature, level of compaction, grading and biggest size of soil particle, split strength and setting time.
