摘要:
采用轴向拉伸与压缩的方式,对混凝土最重要的组分水泥胶砂施加非破坏性的不同级别的荷载,研究在持续荷载作用下材料受力与碳化和氯离子侵蚀速度之间的关系.结果表明,在试验研究的应力区间内,拉压(应力)分别增加(降低)了碳化和氯离子侵蚀速度;应力对氯离子传输速率的影响比对碳化的影响更加明显;相对非破坏性的拉力荷载,压力荷载对材料的传输系数可能会产生相对较大的影响.
Abstract:
Different degree of axial non-destructive compressive and tensile loadings are applied on cement mortar to study the influence of continuous loading on speed of carbonation and chloride ingress. Results show that within the range of the applied forces, compressive or tensile loading decreases or increases the ingress speed of CO2 and Cl-, respectively. Comparing with that for carbonation, influence of loading on speed of Cl- ingress is more obvious. In comparison to that of tensile loading, compressive force may lead to more significant impact on transport properties.
