Advanced progress in recycling municipal and construction solid wastes for manufacturing sustainable construction materials
TL;DR: In this paper, a review of the existing studies on recycling municipal and construction solid waste for the manufacture of geopolymer composites is presented, and the results indicate that although the inclusion of such waste might depress some of the attributes of these composites, proper proportion design and suitable treatment technique could alleviate these detrimental effects and further smooth the recycling progress.
