High-ductility magnesium phosphate cement-based rapid repairing material and preparation method thereof
The invention relates to the field of novel building materials, in particular to a high-ductility magnesium phosphate cement-based rapid repairing material and a preparation method thereof. The rapid repairing material is prepared from the following raw materials in parts by mass: 330 to 893 parts of magnesium oxide, 99 to 372 parts of ammonium dihydrogen phosphate, 82 to 360 parts of retarder, 124 to 744 parts of fly ash, 248 to 496 parts of fine aggregate, 153 to 440 parts of water and 13 to 26 parts of fiber. The high-ductility magnesium phosphate cement-based rapid repair material prepared by the invention integrates rapid hardening, high strength and high ductility, obviously improves the defects of poor tensile deformation resistance and the like of common magnesium phosphate cement, can be used in the field of rapid repair of road and bridge deck concrete pavement layers, reduces traffic blocking time, opens traffic as soon as possible, and improves the repair efficiency. And moreover, the cracking risk caused by poor tensile deformation resistance of the cement-based material of the road and bridge floor can be avoided, and outstanding technical, economic and environment-friendly benefits are achieved.
本发明涉及新型建筑材料领域，具体涉及一种高延性磷酸镁水泥基快速修补材料及其制备方法；所述快速修补材料包括以下质量份配比的原料：氧化镁330~893份，磷酸二氢铵99~372份，缓凝剂82~360份，粉煤灰124~744份，细集料248~496份，水153~440份，纤维13~26份；本发明制备的高延性磷酸镁水泥基快速修补材料，集快硬、高强和高延性于一体，显著改善了普通磷酸镁水泥抗拉变形能力差等缺点，可用于路桥面混凝土铺装层的快速修补领域，减少了交通阻断时间，尽快开放交通，而且可以避免路桥面水泥基材料因抗拉变形能力差引发的开裂风险，具有突出的技术、经济和环保效益。
