Abstract | 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 further impacts the durability of alkali-activated binders. This chapter reviews the pore features of alkali-activated metakaolin (AAM), alkali-activated fly ash (AAFA) and alkali-activated slag (AAS). The water permeability, absorption and chloride iron diffusion are particularly discussed for AAM and AAFA binders, which are two relatively new materials. For comparison purposes, Portland cement binders are also investigated. |
