800 metakaolin (MK) and gravel wash mud (GWM) powders is studied for the development of novel lime-pozzolan pastes. This study examines the influence of varying mixture proportions using different types and compositions of lime powders and GWM at different treatment levels on the mechanical properties ...Altogether nine different compositions of lime-based pastes were prepared and investigated. The first paste (L) consisted of pure lime and it was used as the reference mix. Lime–metakaolin pastes (MK-1–MK-4) contained lime and metakaolin only,
