The invention belongs to the technical field of concrete, and particularly relates to a preparation method of an additive for high-strength concrete. According to the invention, the embedding degree with concrete is increased, the combination degree with concrete is improved and the possibility of cracking of the concrete is reduced by utilizing the porous and pore composite effect of the productduring the use, then free calcium ions, magnesium ions and the like in the concrete are adsorbed by utilizing anionic polyacrylamide on the surface, the ions are deposited in the porous particles or used for filling cracks to achieve a timely repairing effect, the particles adsorb ions and fill the porous particles to gradually improve the mechanical properties of the concrete, meanwhile, due to the addition of the ions, a multi-dimensional net structure is formed in the concrete, the mechanical properties are further enhanced, and due to the enhancement of the particles, the durability of thehigh-strength concrete is improved.
本发明属于混凝土技术领域，具体涉及一种高强度混凝土用添加剂的制备方法。本发明在使用时，首先通过利用产品的多孔隙及孔隙复合效应，增加了与混凝土之间的嵌合度，提高了与混凝的结合度，降低了混凝土的产生裂缝的可能，随后利用表面的阴离子聚丙烯酰胺对混凝土中游离的钙离子、镁离子等进行吸附，沉积在多孔颗粒内部，或对裂缝进行填充，达到及时修补效果，颗粒通过对于离子的吸附，填充多孔颗粒的内部，逐渐增加混凝土的力学性能，同时由于离子的加入，使其内部形成多维网状结构，进一步增强了力学性能，并且由于对于颗粒的增强，提高了高强混凝土的耐久性。
