摘要：
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 Na 2 O 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, respectively. © 2018, Editorial Board of Journal of Harbin Institute of Technology.
