| 摘 要： | 通过对在水泥稳定碎石基层中以粉煤灰等量取代部分水泥的试验研究,考察了粉煤灰水泥稳定碎石的力学性能和收缩性能,结果表明以粉煤灰取代水泥切实可行,不仅具有经济效应,更重要的是具有技术效应,尽管抗压强度、抗拉强度、弹性模量随粉煤灰掺量增加而降低,但在一定范围内,粉煤灰对抗压强度影响很小,而收缩量却显著减少。

| Abstract: | Through the study using part of fly ash to replace equal cement on the base of cement stabilized crushed rock,the mechanical and shrinkage properties of the fly ash and cement corporate stabilized crushed rock are tested.The results show that cement replaced by fly ash is practical,and not only has economical effect,but also has some technical advantages.Even if the compressive and splitting tensile strength as well as elastic modulus decreases with improving fly ash percent,the effect of fly ash on compressive strength is little in a certain range but shrinkage reduced evidently. |
