Quick-setting early-strength basic magnesium sulfate cement and preparation method thereof
The invention discloses quick-setting early-strength basic magnesium sulfate cement and a preparation method thereof, belonging to the technical field of building materials. The invention aims to overcome the problems of complex operation, long time consumption and limited early strength effect in preparation of basic magnesium sulfate cement in the prior art. The preparation method of the invention comprises the following steps: firstly, preparing a basic magnesium sulfate cement seed crystal emulsion through wet ball milling; and adding the emulsion containing seed crystals with different particle sizes and mixing amounts into basic magnesium sulfate cement slurry, conducting stirring at a high speed, performing uniform mixing, pouring the obtained mixture into a mold, and conducting curing in air to obtain the quick-setting early-strength basic magnesium sulfate cement. According to the basic magnesium sulfate cement prepared by the invention, setting time can be regulated and controlled through the particle size and the mixing amount of the seed crystals, and the compressive strength of the basic magnesium sulfate cement cured at 15 DEG C for 12 hours can reach 33 MPa. The method has the advantages of simple process, environment friendliness, high construction efficiency, low cost, capability of meeting the strength requirements of multi-occasion and short-time construction and the like, and is easy to achieve industrial production.
本发明公开了一种快凝早强碱式硫酸镁水泥及制备方法，属于建筑材料技术领域。针对现有技术中制备碱式硫酸镁水泥的操作复杂、耗时长，且早强效果有限的问题，本发明首先使用湿法球磨制备碱式硫酸镁水泥晶种乳状液；然后将含有不同的粒径和掺量的晶种乳状液加入到碱式硫酸镁水泥浆体中高速搅拌混合均匀后浇筑到模具中，在空气中养护固化后得到一种快凝早强碱式硫酸镁水泥。本发明制备的碱式硫酸镁水泥，凝结时间可通过晶种的粒径和掺量进行调控，15℃下养护12h的抗压强度可达33MPa。本发明具有工艺简单、绿色环保、施工效率高、成本低，可满足多场合、短时间施工强度要求等优点，易实现工业化生产。
