摘要:
为研究橡胶颗粒粒径和掺量对橡胶混凝土的峰值应力、峰值应变、割线模量和泊松比的影响变化规律，以C25强度的普通混凝土为基准，用60目胶粉、1～3 mm胶粒及3～6 mm胶粒等体积取代细骨料，配制成100 mm×100 mm×300 mm橡胶混凝土棱柱体试件，通过应变片测定橡胶混凝土在轴心压力作用下的应力-应变曲线。结果表明：与基准混凝土相比，橡胶混凝土的峰值应力、峰值应变和割线模量均较小，且有随着橡胶掺量增大而减小的趋势；橡胶混凝土的泊松比前期比基准混凝土大，后期比基准混凝土小；橡胶颗粒粒径越小时这种差距越大，总体上表现出与橡胶颗粒粒径及掺量之间具有合理的相关关系。
Abstract:
For the purpose of research on the influence of rubber particle size and rubber quantity on peak stress, peak strain, secant modulus and Poisson’s ratio change rule of rubber concrete, a test was made to determine stress-strain curve with strain gauge of C25 ordinary concrete specimens of 100 mm×100 mm×300 mm, which were prepared with rubber powder of sixty mesh, rubber particles of 1-3 mm and 3-6 mm instead of fine aggregate. The results indicate that, compared with the reference concrete, peak stress, peak strain and secant modulus of rubber concrete are smaller and decreased with increment of rubber quantity, while the Poisson’s ratio of rubber concrete is higher than the reference concrete in early period and lower than the reference concrete in later period. The finer the rubber particle size is, the greater difference is. Generally, the research results indicate that there is a reasonable correlation between rubber particle size and rubber quantity.
