摘要: Abstract The partial replacement of high C 3 A cement blended with ground brick (GB) is investigated in terms resistance GB mortar to sodium sulphate (Na 2 SO 4 ) solution. results indicate that the generally increased as level increases up at least 30% replacement. However, types exhibit varying expansion when used and this attributed their chemical phase composition. Sulphate content, glass oxide chemistry are principal factors determine effectiveness resisting expansion. Small amounts do not have any deleterious effects on mortars can be beneficial. Bricks high-calcium or a low proportion glassy should pozzolans. low-calcium make very effective
