Application of the Analytic Hierarchy Process (AHP) to select high performance concretes

Abstract This paper describes an application of the Analytic Hierarchy Process (AHP) to choose the best cement type and mixture for the production of high performance concrete. The decision process aimed at obtaining a concrete that would best meet the requirements of three hypothetical scenarios: (a) industrial concrete floors of a chemical plant, (b) structural elements of a thirty-floor building and (c) a massive foundation block of a green building. In this regard, six different concrete mixtures were evaluated (VR4, IIIR4, V280, III280, V200 and III210) according to four criteria: mechanical properties, durability, financial cost and environmental impact. The analysis results showed that the composition with CPV-ARI cement and content of 280 kg/m3 was the best alternative for scenario (a) and (b), while for scenario (c) the composition with cement CPIII and content of 210 kg/m3 was the best choice.

摘要 本文阐述了层次分析法（Analytic Hierarchy Process，AHP）在遴选高性能混凝土最优水泥类型与拌合配比中的应用。本次决策流程旨在获取可最佳匹配三类假想场景需求的混凝土：(a) 化工厂工业混凝土地面、(b) 三十层建筑结构构件以及(c) 绿色建筑大型基础承台。研究针对六种不同混凝土拌合料（VR4、IIIR4、V280、III280、V200及III210），依据力学性能、耐久性、经济成本与环境影响四项评价准则开展评估。分析结果显示，采用CPV-ARI型水泥且掺量为280 kg/m³的配合比方案为场景(a)与(b)的最优选择，而针对场景(c)，掺量为210 kg/m³的CPIII型水泥配合比方案为最佳选型。
