摘要:
选取试验地点并设计试验方案,对不同粉煤灰掺量的混凝土试块进行现场暴露试验,分析西安盐渍土地区现场暴露的混凝土基于硫酸盐侵蚀试验数据,结合实际环境及材料因素,选取试件的相对动弹性模量和相对质量作为评价参数.比较各评价参数的优劣,提出一个符合实际评价的参数——综合损伤评价参数.理论分析和实验结果表明,室外现场暴露试验混凝土的综合损伤评价参数呈整体下降趋势.运用损伤评价参数能较好地对混凝土在环境作用下的损伤过程进行评判,该方法简捷、可操作性强,但可靠性尚需进一步改进.
Abstract:
By choosing a test place and designing an experimental scheme, we conduct the field exposure experiment for concrete specimens with different fly ash in saline soil area of Xi’an. Combining the practical environment and material factors, we analyze the experimental data based on sulfate attack by calculating the relative dynamic elastic modulus and relative massas evaluation parameters. By comparing the pros and cons of the evaluation parameters, we propose a more practical evaluation parameter named as comprehensive damage evaluation parameter. Theoretical analysis and experimental results suggest that comprehensive damage evaluation parameter shows a general downward trend and it is a more appropriate parameter for concrete damage evaluation. Moreover, the method is simple and easy to operate. However, the reliability is not high enough.
