| 摘 要： | 本文提出了一种改进的表面吸水率试验用于评估混凝土的养护效果。养护的充分与否通过混凝土试件不同深度处的孔结构的差异来判定的方法。研究中利用高性能混凝土的自养护来对此方法的可行性进行了试验验证。试验结果表明：利用此方法测试的孔结构参数受养护条件的显著影响；养护措施不好的情况下，不同深度处混凝土试件的吸水率与孔结构参数差异显著；本方法操作简单、快捷，可以用来评价混凝土的养护效果。尤其适用于高性能混凝土。

| Abstract: | An improved absorption test for assessment of the adequacy of curing for concrete is present. The curing efficiency is evaluated by determining the differences in pore structure at difference depths in test specimens. The approach was applied for self-curing of high performance to verify its feasibility. Experimental results show that the pore structure was sensitive to the curing conditions. There is a significant difference in absorptivity and pore structure at varied depth in concrete in poor curing procedure. The approach, operated simply and quickly, can be used to determine the adequacy of curing for concrete, especially for high performance concrete. |
