Material for secondary reinforcement and shrinkage reduction of concrete, preparation method and concrete
The invention relates to a material for secondary reinforcement and shrinkage reduction of concrete, a preparation method and the concrete.The material comprises adsorption particles and an alkaline aqueous solution, the adsorption particles adsorb the alkaline aqueous solution, the adsorption particles are formed by a water-swellable high-molecular compound, a solute of the alkaline aqueous solution is an alkaline activator, and the solute of the alkaline activator is a water-swellable high-molecular compound. The alkaline aqueous solution contains calcium ions. The shrinkage of the concrete can be reduced, and the strength and durability of the concrete can be improved by promoting secondary hydration of the cementing material.
本申请涉及一种用于混凝土二次增强减缩的材料、制备方法及混凝土，其包括吸附颗粒和碱性水溶液，所述吸附颗粒吸附有所述碱性水溶液，所述吸附颗粒由遇水膨胀高分子化合物形成，所述碱性水溶液的溶质为碱性活化剂，且所述碱性水溶液中含有钙离子。本申请可以降低混凝土的收缩，并能通过促进胶凝材料二次水化来提升混凝土的强度和耐久性。
