Aerated concrete plate beneficial to crushing and recycling and preparation method thereof
The invention discloses an aerated concrete plate beneficial to smashing and recycling and a preparation method thereof, and belongs to the technical field of building materials.The preparation method comprises the steps that a proper pouring forming mold is designed according to the assembly requirement for producing the aerated concrete plate, and a reinforcing mesh is evenly implanted into the mold; heating slurry formed by mixing and stirring the powder to 50-60 DEG C, uniformly stirring, and carrying out gas expansion; and pouring the slurry subjected to gas expansion into the mold planted with the reinforcing mesh, standing for 1.5-2 hours in a clean chamber at the temperature of 40 DEG C, cutting the aerated concrete plate blank subjected to standing, and then conveying the aerated concrete plate blank into a steam curing kettle. According to the invention, the surface of the andalusite waste slag is modified, and the surface of the andalusite waste slag is wrapped with an organic coupling agent, so that the physicochemical properties of the surface of the andalusite waste slag are changed, the compatibility of the andalusite waste slag with an organic polymer, resin and the like is improved, and the dispersity of the andalusite waste slag in the organic polymer is improved; furthermore, the strength, wear resistance and other properties of the aerated concrete plate can be enhanced.
本发明公开了一种利于粉碎和回收的加气混凝土板材及其制备方法，属于建筑材料技术领域，包括：按照所需要生产加气混凝土板材的装配需要，设计出适合的浇筑成型模具，并在模具内均匀植入钢筋网；将粉料混合搅拌成形的浆料，加温至50～60℃，搅拌均匀，发气膨胀；向植有钢筋网的模具内浇筑发气膨胀后的浆料，于净室内40℃的环境下静养1.5‑2小时，将静养好的加气混凝土板材坯体切割后送至蒸养釜中。本发明中，对红柱石废矿渣的表面进行改性处理，采用有机偶联剂对红柱石废矿渣表面进行包裹处理，改变其表面的物理化学性质，提高与有机聚合物、树脂等的相容性，改善其在有机聚合物中的分散性，进而能够增强加气混凝土板材的强度和耐磨性等性能。
