Recycled aggregate reinforced slurry and preparation method thereof
The invention belongs to the technical field of building materials, and discloses recycled aggregate reinforced slurry and a preparation method thereof, and the recycled aggregate reinforced slurry comprises the following components by mass: 5-12% of caustic-burned magnesia powder; 4-16% of magnesium chloride hexahydrate; 1-4% of a super absorbent polymer; and 0.5-1% of a retarding component. The invention further discloses a preparation method of the recycled aggregate. By adopting the technical scheme, the performance characteristics of the magnesium oxychloride cement can be fully utilized, the granular recycled aggregate with excellent performance can be prepared within a short time, and meanwhile, the influence of the water-cement ratio and composition of the concrete adhesion mortar is avoided, and the method can be used for preparing the recycled aggregate from various grades of recycled concrete. The crushing value, the apparent density, the water absorption rate and the firmness of the recycled aggregate prepared by the method meet the I-class requirements of GB/T25177 Recycled Coarse Aggregate for Concrete, the recycled concrete is utilized to the maximum extent, resources are saved, and the environment is protected.
本发明属于建筑材料技术领域，公开了一种利用再生骨料强化浆液及其制备方法，包括下述质量百分比的组分：轻烧镁粉5~12%；六水合氯化镁4~16%；高吸水性聚合物1~4%；缓凝组分0.5~1%。并且本发明还进一步公开了所述再生骨料的制备方法。采用本发明技术方案，可以充分再利用氯氧镁水泥的性能特点，在短时间内制备出性能优异的颗粒状再生骨料，同时本发明不再生混凝土附着砂浆的水灰比和组成的影响，可以用于各种标号再生混凝土制备再生骨料。采用本发明制备的再生骨料压碎值、表观密度、吸水率和坚固性满足GB/T25177《混凝土用再生粗骨料》I类要求，最大化地利用再生混凝土，节约资源，保护环境。
