Experimental study on shear performance of alkali-activated slag ceramsite concrete hollow block masonry
To investigate the shear performance of alkali-activated slag ceramsite concrete hollow block masonry
tests on 108 masonry prisms with Mb25~Mb130 of alkali-activated slag paste and Mb25~Mb80 of alkali-activated slag mortar with pottery sand were carried out. The results show that the shear strength of masonry with alkali-activated slag paste was less than that with alkali-activated slag mortar
and the shear strength of masonry with alkali-activated slag mortar was lower than that with ordinary cement and composite mortars
respectively. The shear strength of masonry increased as the compressive strength of alkali-activated slag paste and mortar increased. The effects of Na2O contents and sand to cementitious materials ratios on the shear strength of masonry should not be ignored. Based on the results
the formulae for the shear strength of alkali-activated slag ceramsite concrete hollow block masonry with alkali-activated slag pastes and mortars were developed
