The influence of secondary crushed stone on the properties of geopolymer concrete
Abstract
The influence of secondary crushed stone on the properties of geopolymer concrete
Incoming article date: 14.04.2025The importance of recycling construction waste for the development of closed-loop economy technologies in the construction industry is considered. The effect of replacing high-quality granite and limestone crushed stone with secondary aggregate obtained by crushing concrete scrap on the strength properties of geopolymer concrete was investigated. It was established that such a replacement does not lead to a decrease in the strength of such concrete, and the impact resistance increases significantly.
