A Qualitative and Quantitative Approach to Prioritize Sustainable Concrete Using TOPSIS
https://orcid.org/https://orcid.org/0000-0002-7162-2929
Cement industry consumes high energy producing emissions and waste to the environment. In order to reduce the effects (environmental impact, energy, and resources) caused by conventional materials, various by-products and pozzolanic materials are used to achieve sustainable concrete. Assessing the sustainable performance of concrete based on multiple conflicting attributes is decisive and compelling. It is difficult to choose an alternative among various supplementary cementitious material (SCM) with respect to a set of qualitative and quantitative performance attributes. The present study utilizes and explores the importance of Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) in selecting the best sustainable cementitious material. The study has considered five different concretes made of OPC, fly ash, GGBS, metakaolin, and composite cement at a particular grade and observed their performance based on ten qualitative attributes and eight quantitative attributes (workability, compressive strength, split tensile, flexural strength, sorptivity, and life-cycle cost). From the results, it was observed that considering all attributes, fly ash-based concrete has higher performance and is prioritized among others. The developed approach facilitates the decision-makers in the selection of a sustainable alternative.
