Abstract :
Recycling is turning a by-product source material to a low-cost usable material. On the other hand, the term upcycling refers to a process of using a low-cost by-product source material (such as low-calcium fly ash) to produce a material (geopolymer concrete) that is of higher value than the source material. Extensive studies have been conducted on fly ash-based geopolymer concrete; the results of these studies have been reported in the literature. This paper focuses on some recent applications of geopolymer concrete in the precast construction.
