摘要利用固体废弃物制备磷酸镁水泥不仅可降低其成本,同时也是优化其性能的重要途径。本工作在分析不同M/P对磷酸镁水泥的凝结时间、流动度及力学性能影响的基础上,研究了采用钢渣、粉煤灰配制的磷酸镁水泥在不同养护条件下的性能特征。结果表明:随着M/P的增加,磷酸镁水泥的流动度减小,凝结时间缩短;当M/P=3时,磷酸镁水泥抗压强度达到最高;磷酸镁水泥中掺粉煤灰较掺钢渣具有更好的耐水性;在空气中养护时,提高钢渣、粉煤灰掺量,磷酸镁水泥砂浆收缩量也增大;而在水中养护,钢渣和粉煤灰会降低磷酸镁水泥的收缩,后期甚至出现一定膨胀。

Abstract: Utilizing solid waste in preparing magnesium phosphate cement (MPC) can reduce its cost, and it is an important way to improve the performance. In this study, the effect of MgO to phosphate ratio on the setting time, fluidity and mechanical properties of prepared MPC were investigated. The performance of MPC containing steel slag and fly ash under different curing conditions were characterized. Results showed that: with the increase of M/P, the fluidity of MPC decreased and the setting time was shortened significantly. The compressive strength of MPC reached the highest at the M/P of 3. The samples made with steel slag showed poorer water resistance compared with that of fly ash blended system. The shrinkage of MPC mortar was also increased by increasing the amount of steel slag and fly ash when the specimens were cured in the air. However, the incorporation of steel slag and fly ash could reduce the shrinkage as the specimens stored in water, and the samples even exhibit expansion at late age.

Key words: magnesium phosphate cement steel slag fly ash water resistance shrinkage expansion
