Effects of dosage of alkali-activated solution and curing conditions on the properties and durability of alkali-activated slag concrete

Influence of admixtures on the properties of alkali-activated slag mortars subjected to different curing conditions

“…Therefore, the highest compressive strengths of 28 days were obtained from AAS mortars exposed to 23 ± 2°C with 95% relative humidity. These findings comply with those of other researches [11,[25][26][27][28] reporting that the strength development of AAS binder was susceptible to the type of curing environment. They also stated that a lack of moist curing reduced compressive strength, increasing the level of micro cracking in comparison with moist curing.…”

Durability of mortar and concrete containing alkali-activated binder with pozzolans: A review

“…Even as mentioned later, the strength of 6% NH concrete cured at normal condition (38°C, 100% relative humidity) is very close to that of concrete with both activators, especially at later age. Chi [58] reported that sulphate resistance of AAS concrete is better than OPC concrete. Moreover, Bakharev et al [59] reported that compressive strength decreases up to 20% for OPC concrete and up to 15% for AAS concrete due to immersion in 5% MgSO 4 solution after a 3-month.…”
