Compressive Behaviors of High-Strength Geopolymeric Concretes: The Role of Recycled Fine Aggregate

Huaicheng Zhong,
Huanchang Fu,
Yuan Feng
et al.

Abstract: In this study, natural fine aggregates (NFAs) in high-strength fly ash (FA)/ground granulated blast furnace slag (GGBFS)-based geopolymer concretes were both partially and completely replaced by RFAs to prepare geopolymer recycled fine aggregate concrete (GRFC). Herein, the impacts of RFA content (0%, 25%, 50%, 75%, and 100%) on the fresh and hardened performance and microstructural characteristics of a GRFC were investigated. The results indicated that with increasing RFA substitution ratio, the setting time … Show more
