The utilization of eco-friendly recycled powder from concrete and brick waste in new concrete: A critical review
TL;DR: In this article, the median diameter and replacement ratio of Recycled Powder (RP) concrete should be below 30μm and 30%, respectively, to improve the durability of concrete when the RP fineness is superior to the cement fineness.

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.
