基于层次分析法的清水混凝土外观性能评价

Appearance performance evaluation of fair-faced concrete based on analytic hierarchy process

独特的外观性能是清水混凝土区别于普通混凝土的关键,但目前仍无标准的方法综合评价其外观性能。根据层次分析法设定"清水混凝土外观性能评价"为一级指标,下设4个二级指标和8个三级指标,建立了一套清水混凝土外观性能的综合评价方法,该方法能根据清水混凝土外观性能各项指标的重要程度,对其进行合理的综合评价。采用此方法确定了长沙金鹰广场清水混凝土项目的混凝土最优配合比,并运用于其工程验收时的抽检评价。

Although unique appearance performance is critical distinction between fair-faced concrete and ordinary concrete,there is no standard method to integratedly evaluate appearance performance of fair-faced concrete. Based on analytic hierarchyprocess,this paper develops an integrated evaluation method of fair-faced concrete by taking appearance performance of fair-facedconcrete as fii＇st-level index, proposing four second-level iudexes and eight third-level indexes. The appearance performance is rea-sonably evaluated according to importance of each index. Finally, the method is applied in a real-world case of Changsha GoldenEagle Plaza to compute optimum mix ratio and make evaluation in acceptance of work.
