Alkali-excitation-based Yellow River sediment brick and preparation method thereof
The invention belongs to the technical field of cementing materials, provides a Yellow River sediment brick based on alkali excitation and a preparation method thereof, and solves the problem that Yellow River sediment is difficult to treat. The Yellow River sediment brick comprises the following raw materials: Yellow River sediment, an alkali activator, silica fume, slag, fly ash, Portland cement and water. The main mineral components in the Yellow River silt are quartz, albite, microcline, calcium carbonate and the like, the alkali activator is used for activating the Yellow River silt, the content of silicon-aluminum ions and clay particles capable of participating in the reaction in the Yellow River silt is increased, the stability of aggregates is improved, the Yellow River silt can be more easily subjected to chemical reaction with the cementing material, and the cementing material is more stable. Therefore, a large amount of hydration products are generated to tightly bond the Yellow River sediment particles with the cementing material, and the strength of the brick is improved. The invention also provides a preparation method of the Yellow River sediment brick based on alkali excitation, the raw materials are combined together in a step-by-step stirring mode, and the high-performance brick is obtained through combination of vibration molding and a steam curing system.
本发明属于胶凝材料技术领域，提供了一种基于碱激发的黄河泥沙砌砖及其制备方法，解决了黄河泥沙难以处理的问题。该黄河泥沙砌砖包含下列原料：黄河泥沙、碱激发剂、硅灰、矿渣、粉煤灰、硅酸盐水泥和水。黄河泥沙中的主要矿物成分是石英、钠长石、微斜长石、碳酸钙等，使用碱激发剂活化黄河泥沙，提高了黄河泥沙中可参与反应的硅铝离子和黏土颗粒的含量以及团聚体的稳定性，使黄河泥沙更易与胶凝材料发生化学反应，从而生成大量的水化产物将黄河泥沙颗粒与胶凝材料紧密粘结，提升砌砖的强度。本发明还提供了基于碱激发的黄河泥沙砌砖的制备方法，本发明通过分步搅拌的方式将各原料结合在一起，振动成型和蒸养制度的结合，得到了高性能的砌砖。
