Activated lithium salt solid waste for ultra-high performance concrete as well as preparation method and application of activated lithium salt solid waste
The invention relates to the technical field of building cementing materials, and discloses an activated lithium salt solid waste for ultra-high performance concrete and a preparation method and application thereof.The activated lithium salt solid waste is attached to the surface of the lithium salt solid waste or enters internal gaps of the lithium salt solid waste through composite activating agent particles and is tightly combined with the lithium salt solid waste particles, and the composite activating agent particles are used for activating the lithium salt solid waste; therefore, the surface structure of the lithium salt solid waste powder is improved, the problem that the lithium salt solid waste powder is prone to agglomeration is solved, and the combination mode of the lithium salt solid waste powder and cement can be optimized. In the cement hydration process, hydration products preferentially grow on the surfaces or gaps with the composite activator particles, air in the gaps of the lithium salt solid waste can be discharged, and the problem that bubbles exist in an ultra-high performance concrete matrix and are difficult to discharge due to the fact that the lithium salt solid waste is difficult to fill is solved; the combination between the lithium salt solid waste and the hydration product is further enhanced, and the strength performance and the stability of the lithium salt solid waste-based ultra-high performance concrete (UHPC) are favorably improved.
本发明涉及建筑胶凝材料技术领域，公开了用于超高性能混凝土的活化锂盐固废及其制备方法和应用，本发明的活化锂盐固废利用复合活化剂微粒在锂盐固废表面附着或进入其内部空隙，并与锂盐固废颗粒紧密结合，从而实现锂盐固废粉末表面结构改善，解决锂盐固废易团聚的问题，且能优化锂盐固废粉末与水泥的结合方式。在水泥水化过程中，水化产物会优先在具有复合活化剂微粒的表面或空隙生长，不仅有利于排出锂盐固废空隙内部的空气，改善锂盐固废内部难填充导致超高性能混凝土基体内部存在气泡且难以排出的问题，还进一步加强了锂盐固废与水化产物之间的结合，有助于提高锂盐固废基超高性能混凝土(UHPC)的强度性能和稳定性。
