Alkali-silica reaction (ASR) is one of the major durability issues in ordinary Portland cement (OPC) concrete. Previous literature suggested that the alkali-activated slag (AAS) concrete is less susceptible to ASR compared to OPC concrete.

Effect of Metakaolinite on Properties of Alkali Activated Slag Materials
Key Engineering Materials, 2018Metakaolinite was introduced to alkali activated slag mortars and pastes. Properties of fresh and hardened mortars as well as phase composition and microstructure of hardened pastes were investigated. Introduction of metakaolinite both as addition as well as substitution of slag results in severe decrease in strength of the mortars.

Shrinkage mitigation strategies in alkali-activated slag
Cement and Concrete Research, 2017Abstract In this work, three shrinkage mitigation strategies (i.e. high-temperature curing, sulfate-enrichment, and calcium-enrichment) were evaluated and their effectiveness in mitigating shrinkage of alkali-activated slag (AAS) was studied. The results show that the cause of high-magnitude shrinkage in AAS is attributed to the high visco-elastic ...

Kinetic study on hydration of alkali-activated slag
Cement and Concrete Research, 1993The mechanism and kinetics of hydration of alkali-activated slag (AAS) have been studied. Heat of hydration, non-evaporable water content and hydration degree of AAS were examined. Similar to ordinary Portland cement (OPC), the hydration process of AAS could be classified into five stages: initial, induction, acceleration, deceleration and decay, but ...

A Review of Alkali-Activated Slag as Cement Replacement
Key Engineering Materials, 2019Alkali activated slag (AAS) offers opportunities to the construction industry as an alternative to ordinary Portland cement (OPC). The production of OPC and its use contributes significantly to release of CO2 into the atmosphere while AAS is an industrial by-product that contributes much less to the environmental footprint that needs to be recycled if ...
