粉煤灰对水泥稳定碎石材料力学性能的影响

Research on the Influence of Fly Ash on the Mechanic Performance of Cement Stabilized Crushed Stones

针对国内外对于水泥粉煤灰稳定碎石材料的力学性能研究不够完善、系统,力学参数不够合理、材料无法推广应用等问题,通过系统研究粉煤灰对水泥稳定碎石材料的早期强度、长期强度、劈裂强度以及回弹模量等力学性能的影响,探讨了粉煤灰对水泥稳定碎石材料的力学性能影响规律,为水泥粉煤灰稳定碎石材料的改性机理研究、合理力学设计参数研究提供了必要的基础。

The research on the mechanic performance of cement and fly ash stabilized crushed stones is not perfect and systemic. The mechanic parameters are not reasonable and its application is not abroad, The influence of fly ash on its early strength, long strength, splitting tensile strength and modulus is studied in this article. The influence rule of fly ash on cement stabilized crushed stones is also studied in this article. The study provides the necessary base on the modification mechanism and the reasonable mechanical design parameters,
