摘要：研究了高吸水性树脂（SAP）作为内养护材料对碱矿渣水泥砂浆抗压强度和收缩性能的影响。研究结果表明，掺加预吸水SAP可引起强度下降，下降幅度随着附加水胶比的增加而增大；SAP可大幅降低碱矿渣水泥砂浆的自收缩，但对绝对干燥收缩的影响较小，甚至可能会使其有所增加。 Abstract: The effect of super absorbent polymer(SAP) on the compressive strength and shrinkage of alkali activated slag cement mortar was studied. The results show that SAP may cause a decrease in strength and the strength decreases faster with the increase of W/C. SAP can greatly reduce the autogenous shrinkage of alkali activated slag cement mortar while it has little effect on absolute drying shrinkage, sometimes it may lead to an increase in absolute dry shrinkage.
