Anti-crack thermal-insulation concrete material for subway station and preparation method of anti-crack thermal-insulation concrete material
The invention discloses a subway station anti-crack thermal insulation concrete material and a preparation method thereof, and belongs to the technical field of concrete materials. The preparation method provided by the invention comprises the following steps: drying and crushing shield muck, expanded quartz and expanded vermiculite, uniformly stirring and mixing according to a mass ratio of (8-12): (0.8-1.2): (0.8-1.2), adding water, uniformly mixing, and granulating to obtain raw material balls; drying the raw material nodules, preheating, and calcining to obtain porous ceramsite; uniformly mixing the porous ceramsite, the cement, the fine sand, the silica fume and the fly ash, adding the water reducing agent aqueous solution, stirring, adding the foamed protein-based foaming agent aqueous solution, and uniformly stirring again to obtain the product. According to the method, a large amount of shield muck solid waste can be consumed, the production process is simple, the cost is low, large-scale application is easy, and the prepared concrete material has good crack resistance and heat preservation performance.
本发明公开了一种地铁车站抗裂保温混凝土材料及其制备方法，属于混凝土材料技术领域。本发明提供的制备方法包括如下步骤：将盾构渣土、膨胀石英和膨胀蛭石干燥粉碎后按质量比为(8～12)：(0.8～1.2)：(0.8～1.2)搅拌混匀，然后加水调匀后进行造粒，得到生料球；将所述生料球干燥、预热后进行煅烧，得到多孔陶粒；将所述多孔陶粒、水泥、细砂、硅灰、粉煤灰拌合均匀，加入减水剂水溶液，搅拌后加入发泡后的蛋白质基发泡剂水溶液，再次搅拌均匀，即得。本发明上述方法能够实现盾构渣土固废的大量消纳，生产过程简单且成本低，易于大规模应用，而且制备得到的混凝土材料具有良好的抗裂保温性能。
