Through experiments with two generations of recycled aggregate concrete and the application of Multi-Criteria Decision-Making techniques, this research aims to establish a sustainable framework of second generation recycled aggregate concrete selection. The technical and environmental performances of seven concrete mixtures were evaluated experimentally and analytically. In addition to the control mixture, six mixtures were produced with two proportions of recycled concrete aggregate or multi-recycled concrete aggregate (30 % and 70 %). Four Multi-Criteria Decision-Making techniques, namely TOPSIS, EDAS, WSM, and WPM, were applied for optimizing the best concrete mixture in terms of technical and environmental based. The results of the four techniques agreed that reusing recycled aggregate concrete is possible as high quality and environmentally friendly concrete. Yet the highest CO2 emissions have belonged to the control mixture where no recycled or multi-recycled aggregate concrete was used. |
