摘要:
废橡胶颗粒、水泥和粉煤灰混合制成一种新型轻质填料,通过对橡胶水泥粉煤灰轻质填料进行三轴压缩试验,分析不同橡胶掺量和固结压力对轻质填料应力-应变关系以及受力机制的影响。结果表明:随着固结压力的增加,轻质填料的强度与刚度随之增加; 当橡胶掺量增加时,应力-应变曲线形状变化明显,其破坏应变呈现增长趋势,破坏应力呈现递减的趋势,在较低围压时应力-应变曲线呈现软化型,高围压下呈现硬化型。
Abstract:
Rubber cement and fly ash(RCF)were mixed to a type of lightweight material.RCF were used in a serial of triaxial compression test to examine the influences of different rubber contents and confining pressures on the behaviors of RCF.The result showed that with confining pressure increased,the strength and the stiffness of the lightweight material increased.When the rubber content increased,the stress strain curve shape changed.Its failure strain showed a growing trend and the failure stress showed a decreasing trend.At high confining pressure,the curve showed a weak hardening type; at low confining pressure,it showed a softening type.
