Li, Z. (author), Chen, Y. (author), Provis, John L. (author), Cizer, Özlem (author), Ye, G. (author)This paper provides a critical review on autogenous shrinkage of alkali-activated slag (AAS). It is reported that AAS paste, mortar, and concrete generally show larger autogenous shrinkage than Portland cement (PC) counterparts. Self-desiccation is the main driving force of the autogenous shrinkage of hardened AAS, but other mechanisms also...review 2023

Li, Z. (author), Lu, T. (author), Liang, X. (author), Dong, H. (author), Ye, G. (author)This study aims to provide a better understanding of the autogenous shrinkage of slag and fly ash-based alkali-activated materials (AAMs) cured at ambient temperature. The main reaction products in AAMs pastes are C-A-S-H type gel and the reaction rate decreases when slag is partially replaced by fly ash. Due to the chemical shrinkage and the...journal article 2020
