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。
Aimed at the low early strength of lime-fly ash stabilized pellets and the poor anti-cracking performance of cement stabilized pellets, the strength and crack resistance of cement-lime fly ash stabilized grit were studied through a large number of laboratory tests and theoretical analysis. And compared with cement and fly ash stabilized grit and lime fly ash stabilized grit, so as to obtain a reasonable proportion of cement lime and fly ash stabilized grit with early strength and later strength, crack resistance and other characteristics.
