摘　　要：研究了沸石粉掺量对磷酸镁水泥砂浆力学性能、干燥收缩、凝结时间和流动度的影响。结果表明:沸石粉的掺入虽然使MPC砂浆的流动度和力学性能降低,但显著延长了MPC砂浆的凝结时间,并随着沸石粉掺量的增大先增长后降低,与此同时,MPC砂浆的干燥收缩与耐水性能也有较明显的改善。The effects of zeolite powder content on the mechanical properties,drying shrinkage,setting time and fluidity of magnesium phosphate cement mortar were studied.The results showed that although the fluidity and mechanical properties of MPC mortar were reduced by the addition of zeolite powder,the setting time of MPC mortar was significantly prolonged,and increased first and then decreased with the increase of zeolite powder content.At the same time,the drying shrinkage and water resistance of MPC mortar have also been significantly improved.

关 键 词：沸石粉 磷酸镁水泥砂浆 力学性能 流动度 凝结时间
