| 摘 要： | 各学者提出的抗裂评价指标是根据混凝土不同结构用途提出来的,考虑的问题各有侧重。在工程实践中,应该突出主要矛盾,合理采用单一性能指标或综合评价指标对混凝土的抗裂性能进行评价。提出了理想化抗裂评价指标,并用其对临江和龙滩工程的碾压混凝土和常态混凝土进行评价,得出碾压混凝土的抗裂性能优于常态混凝土以及早期二级配碾压混凝土抗裂性能优于三级配,而后期三级配碾压混凝土的抗裂性能较优的结论。

| Abstract: | Different scholars aecording to the different purposes of eoncrete structures put forward different evaluation indexes for crack resistance of concrete. In the project praetice, we should adopt suitable indexes to evaluate crack resistance of conerete in aecordance with the characteristics of specific projects and tests. This paper puts forward ideal crack resistanee evaluation indexes that were used to the evaluation on the RCC and common concrete of Linjiang and Long-tan projects. And we make the conclusions that the crack resistance of RCC is better than common conerete and that of grade-II RCC is better than that of grade-III RCC at early age, but that grade-III RCC is better than that of grade-II RCC at late. |
