摘要
针对石灰粉煤灰稳定粒料早期强度较低和水泥稳定粒料抗裂性能较差的问题,通过大量的室内试验和理论分析,研究了水泥石灰粉煤灰稳定砂砾的强度和抗裂性能,并与水泥粉煤灰稳定砂砾和石灰粉煤灰稳定砂砾进行比较,从而得到配比合理的水泥石灰粉煤灰稳定砂砾具有早期强度和后期强度高、抗裂性能优异等特性。
As to the problems of low early strength of aggregate stabilized with lime and fly-ash(ASLF)and bad anti-cracking property of aggregate mixture stabilized with cement(ASC),and through a great lot of indoor tests and theory analysis,properties of strength and anti-cracking of aggregate stabilized with cement, lime and fly-ash (ASCLF) are researched in this paper. At the same time the property of ASCLF is compared with ASC and ASLF,and the optimum proportion of ASCLF has better properties of early and later strength and anti-cracking are found.
