摘要
通过混凝土抗压强度试验,以孔隙率和水胶比为主要影响因素,探讨多孔混凝土的静压应力-应变关系和静弹性模量特性。通过对比分析表明:孔隙率对于多孔混凝土应力-应变曲线的影响较为显著。随着孔隙率的增大,多孔混凝土在受压过程中发生不均匀变形和突然性破坏的概率会逐渐上升。此外,多孔混凝土的静弹性模量会随着孔隙率的增大而降低,且呈现出与抗压强度同步升高或降低的趋势。
In this study,the compressive strength test was carried out to examine the influence of void ratio and water-binder ratio on stress-strain relationship and static modulus of elasticity characteristic of porous concrete. After the comparion and analysis,the stress-strain curve of porous concrete was significantly affected by the void ratio.During the compression process,the probabilities of non-uniform deformation and sudden failure of porous concrete were increased gradually with the increase of void ratio. In addition,the static modulus of elasticity of porous concrete was lowered with the increase of void ratio. Moreover,the static modulus of elasticity was increased or decreased with an increase or decrease in the compressive strength.
