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。
By compressive strength test of concrete, porosity and water-cement ratio as the main influencing factors, the static pressure stress-strain relationship of porous concrete and static modulus properties. The comparative analysis shows that the influence of porosity on the stress-strain curve of porous concrete is significant. With the increase of porosity, the probability of uneven deformation and sudden failure of porous concrete during compression will gradually increase. In addition, the modulus of elasticity of porous concrete decreases with the increase of porosity, and tends to increase or decrease synchronously with compressive strength.
