Strong retarding cementing material and preparation method thereof
The invention relates to the technical field of gelling materials, in particular to a strong retarding gelling material and a preparation method thereof.The strong retarding gelling material comprises polymer dots and Portland cement, the polymer dots and the Portland cement are compounded, a retarder does not need to be additionally added, and the setting time of the gelling material is greatly prolonged. Compared with ordinary Portland cement, the strong retarding cementing material has the advantages that the setting time can be prolonged by more than 4 times, and the mechanical property is not obviously reduced. The strong retarding cementing material has the advantages of simplicity in preparation, strong retarding effect, no negative influence on mechanical properties in the later period of cement maintenance and the like, and can be widely applied to special projects such as long-distance concrete transportation, large-volume concrete pouring, high-temperature environments and the like.
本发明涉及胶凝材料技术领域,具体为一种强缓凝胶凝材料及其制备方法,该强缓凝胶凝材料包括聚合物点和硅酸盐水泥,将聚合物点与硅酸盐水泥复合,不需要额外添加缓凝剂,大大延长了胶凝材料的凝结时间。与普通硅酸盐水泥相比,该强缓凝胶凝材料凝结时间可提高4倍以上,其力学性能未有明显下降。该强缓凝胶凝材料具有制备简单、强缓凝效果、对水泥养护后期力学性能无负面影响等优点,可广泛应用于远距离运输混凝土、大体积混凝土浇筑、高温环境等特殊工程。
