摘要
对采用不同橡胶掺量、不同橡胶粒径组合的低掺量橡胶混凝土进行单轴受压试验,研究分析橡胶掺量、粒径对低掺量橡胶混凝土的轴心抗压强度、弹性模量、峰值应变、极限应变、裂缝以及试件破坏形态等力学性能的影响,对这些影响给出了相应的机理分析。
Uniaxial compressive experiment for low content rubber concrete whit different rubber content and different particle size was conducted. The influence of rubber content and rubber particle size on the mechanical property index of low content rubber concrete was investigated. The mechanical property index includes axial compressive strength, elastic modulus, peak strain, ultimate strain, appearance of visible cracks and failure pattern of specimens.And mechanism analysis of test result is conducted.
