Abstract

Due to resource scarcity, environmental impact, and socioeconomic constraints, sustainable criteria should be given prime importance in the construction industry. The sustainability in concrete can be attained using supplementary materials. The numbers of supplementary concrete materials (SCMs) are available ranging from industries by-products, agro-products, waste product, and newly engineered materials. The selection of the supplementary materials is challenging due to the wide range of environmental, technical, and economic constraints. The paper proposes a decision support framework considering technical, environmental, social, and economic sustainability criteria for ranking of concrete supplementary material. The decision framework includes the optimal scoring method- (OSM-) based shortlisting of supplementary materials, with technical and cost characteristics, and subsequent prioritizing material according to sustainable potentiality order using AHP-TOPSIS. The stability of the ranking of sustainable concrete supplementary materials has been verified using sensitivity analysis. The present study develops decision support framework by employing technical characteristics of the most technically sound material used as concrete material. The technical, environmental, and socioeconomic sustainable performance indicators have considered its selection to obtain much needed sustainability and to boost the eco-friendly environment. From the proposed MCDM framework, it is found that engineered siliceous materials and agriculture-based industrial waste products as SCMs will prove to be most sustainable in the construction industry.

  • Claisse et al [4] have provided an account of research on new ingredients to concrete. e multicriteria decision-making (MCDM) approach has been widely used in the construction industry for the selection of alternatives for construction plans, methods, activities, and materials, in relation to sustainable performance. e environmental aspects, social and economic issues based selection model is developed by Abeysundara et al [5] for sustainable building materials, and they concluded that environmental criteria have to be Advances in Materials Science and Engineering preferred over the social and economic criteria for sustainable building construction. e basic characteristics of the concrete supplementary materials and their role in concrete are well documented in the literature [6]

Introduction

Environmental impact, and socioeconomic constraints, sustainable criteria should be given prime importance in the construction industry. e sustainability in concrete can be attained using supplementary materials. e numbers of supplementary concrete materials (SCMs) are available ranging from industries by-products, agro-products, waste product, and newly engineered materials. e selection of the supplementary materials is challenging due to the wide range of environmental, technical, and economic constraints. e paper proposes a decision support framework considering technical, environmental, social, and economic sustainability criteria for ranking of concrete supplementary material. e decision framework includes the optimal scoring method- (OSM-) based shortlisting of supplementary materials, with technical and cost characteristics, and subsequent prioritizing material according to sustainable potentiality order using AHP-TOPSIS. e stability of the ranking of sustainable concrete supplementary materials has been verified using sensitivity analysis. e present study develops decision support framework by employing technical characteristics of the most technically sound material used as concrete material. e technical, environmental, and socioeconomic sustainable performance indicators have considered its selection to obtain much needed sustainability and to boost the eco-friendly environment. E paper proposes a decision support framework considering technical, environmental, social, and economic sustainability criteria for ranking of concrete supplementary material. E decision framework includes the optimal scoring method- (OSM-) based shortlisting of supplementary materials, with technical and cost characteristics, and subsequent prioritizing material according to sustainable potentiality order using AHP-TOPSIS. The combined approach of OSM-AHP-TOPSIS has been implemented for the ranking of supplementary construction materials using known technical characteristics and sustainability performance indicators. E five decision-makers having vast working experience of more than five years constituted the team Apart from their own expertise, they considered the views of construction material experts, environmentalists, geotechnical experts, and government units to provide more robustness to the final output of sustainable materials selection.
