13.3 Reuse of recycled aggregates in alkali-activated
mortars and concrete

AASc and AAS mortar (AASm) are a novel invention to replace conventional con-
struction materials. The main variation respect to conventional cement-based mate-
rials is the replacement of OPC in their manufacture, by substituting comparatively
alkali-rich clinker-free binder matrix namely AAS or geopolymer. In this section
the application of AAMs in concrete and mortar manufacture is explained.

13.3.1 Composition and content of alkali-activated slag mortars
and concrete (AASm and AASc)

AASc and AASm are an environmental friendly, and these materials must be con-
sidered as a part of the sustainable development (Kathirvel et al., 2016). Also, RA,
