External sulfate attack on alkali-activated slag

Construction and Building Materials, 2013
Abstract This paper analyses the effects of external sulfate attack (5% Na2SO4 solution) on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/А-S 42.5N) was used as a benchmark material. External sulfate attack led to a decrease in strength of CEM II, but not of AAS.

Effect of alkali dosage and silicate modulus on carbonation of alkali-activated slag mortars

open access: yesCement and Concrete Research, 2018
The long-term durability and their mechanisms of alkali-activated cement based materials have remained largely elusive. In this paper, carbonation of alkali-activated slag (AAS) mortars activated by NaOH and waterglass with different alkali dosages and ...

Decalcification resistance of alkali-activated slag

Journal of Hazardous Materials, 2012
This paper analyses the effects of decalcification in concentrated 6M NH(4)NO(3) solution on mechanical and microstructural properties of alkali-activated slag (AAS). Portland-slag cement (CEM II/A-S 42.5 N) was used as a benchmark material. Decalcification process led to a decrease in strength, both in AAS and in CEM II, and this effect was more ...
