摘要 以磷酸二氢钾、氧化镁、硼砂和粉煤灰为原料,按一定比例制备磷酸镁水泥,以工作性能和强度为指标,研究了水胶比、氧化镁与磷酸盐摩尔比(M/P)、硼砂及粉煤灰掺量对磷酸镁水泥性能的影响;采用X射线衍射仪与扫描电子显微镜研究了磷酸镁水泥水化产物及粉煤灰对其结构和性能的影响。结果表明,当水胶比为0.34,M/P=3/1,掺10%硼砂和40%粉煤灰时磷酸镁水泥强度最高,达到54.2MPa。

Abstract:  In this paper, potassium phosphate, magnesium oxide, borax and fly ash were used as raw materials to prepare magnesium phosphate cement(MPC) by a certain percentage. The workability and strength were used as indicators to study the effects of water-to-binder ratio, magnesium oxide and phosphate molar ratio (M/P), borax and fly ash on the properties of MPCs. X-ray diffractometer and scanning electron microscope were used to investigate the hydration product of MPCs and the effect of fly ash on it. The results show that when water-to-binder ratio is 0.34, M/P=3/1, mixed with 10% borax and 40% fly ash, the strength of MPCs is the highest, reaching 54.2 MPa.
Key words:  magnesium phosphate cement (MPC)    fly ash    water-to-binder ratio
