Li, Z. (author), Wyrzykowski, Mateusz (author), Dong, H. (author), Zhang, Shizhe (author), Lura, Pietro (author), Ye, G. (author)Alkali activated slag (AAS) has shown promising potential to replace ordinary Portland cement as a binder material. Synthesized from industrial by-products, AAS can show high strength, thermal resistance and good durability. However, AAS has been reported to exhibit high autogenous shrinkage. Autogenous shrinkage is a critical issue for building...conference paper 2021

Liang, X. (author), Dong, H. (author), Li, Z. (author), van Zijl, Marc Brito (author), Ye, G. (author)This paper investigated the feasibility of using biomass fly ash (BFA) to prepare alkaliactivated slag and fly ash paste. The reference mixture was alkali-activated slag and coal fly ash (CFA) paste with a slag-to-coal fly ash ratio of 50/50. In other mixtures, coal fly ash was replaced at 40% and 100% with BFA, respectively. The results showed...conference paper 2021

Ren, Jie (author), Zhang, Lihai (author), Zhu, Yingcan (author), Li, Z. (author), San Nicolas, Rackel (author)This study compares the degradation behavior of the alkali-activated slag/fly ash (AASF) and ordinary Portland cement (OPC) mortars exposed to phosphoric acid with different pH values. The experimental results show that AASF mortars exhibit better resistance than OPC mortars against surface damage, although both systems get white deposits on the...journal article 2022
