Investigation of shrinkage mechanism of alkali-activated slag

Case Studies in Construction Materials
Slag is a highly active waste product that can be added to alkali-activated cement to improve their mechanical properties, but also creates significant shrinkage, which limits its usefulness. This study examines the reasons behind the shrinkage of alkali-activated slag (AAS).

Analysing the relation between pore structure and permeability of alkali-activated concrete binders

, 2015
Alkali-activated binders are usually porous materials that consist of various scales of pores, gels and residual raw material particles. The importance of pore structure has been highlighted in recent studies as it impacts the permeability of fluids and ...

Assessment of the performance of alkali-activated slag/fly ash using liquid and solid activators: early-age properties and efflorescence

The use of solid activators to prepare alkali-activated materials (AAM) holds great potential for on-site applications, as it eliminates the need to transport and store large quantities of concentrated alkaline solutions.
