基于模糊理论与层次分析法,建立了混凝土耐久性指标同粉煤灰掺量、含气量、水胶比以及单位用水量4个新拌混凝土指标之间的量化关系模型,通过计算可得硬化混凝土耐久性指标数值,根据给出的评价标准,可以及时评价硬化混凝土耐久性的优劣,便于在施工过程中及时调整粉煤灰掺量、含气量、水胶比以及单位用水量,得到耐久性良好的硬化混凝土。 Based on fuzzy theory and analytic hierarchy process (AHP), the quantitative relationship model between the concrete durability index and the content of fly ash, gas content, water-cement ratio and unit fresh water content was established. According to the calculation, Durability index values, according to the evaluation criteria given, you can timely evaluation of the durability of hardened concrete pros and cons, to facilitate the timely adjustment of the construction process of fly ash content, gas content, water binder ratio and the unit of water to obtain durability Good hardened concrete.
