Abstract:

In this study, fly ash and ground granulated blast furnace slag combination-based geopolymer concrete containing recycled aggregate (RA) are developed and evaluated. The effects of slag content and RA replacement on the performance of geopolymer concrete were studied, including the physical and mechanical properties. Additionally, the scanning electron microscopic experiments were performed to investigate the microstructures. The results show that the RA replacement indicates an insignificant influence on the setting time and workability, while it results in a reduction in the mechanical properties. The slag inclusion reduces the setting time and workability. However, improved mechanical properties can be obtained in the geopolymer concrete due to the slag inclusion. Also, this effect is more obvious in the geopolymer concrete containing RA.
