Steel fiber modification method and application thereof in concrete
The invention belongs to the technical field of buildings, and discloses a modification method of steel fibers and application of the steel fibers in concrete. The preparation method comprises the following steps: weighing polyallylamine hydrochloride (PAH), dissolving in a phosphoric acid buffer salt solution (PBS), fully stirring to obtain a PAH solution with a specific concentration, and preparing a sodium silicate solution with a certain concentration for later use; the steel fibers are placed in a PAH solution to be soaked for specific time, then taken out and cleaned with clear water; the cleaned steel fibers are further placed in a sodium silicate (Na2SiO3) solution with a certain concentration to be subjected to dipping treatment for a specific time; taking out the steeped steel fibers, and cleaning with clear water; and 5, drying the cleaned steel fibers to constant weight, and cooling to room temperature for later use. The quality of the steel fibers can be further improved, the strength and durability of the concrete can be remarkably enhanced, and the concrete has very positive effects on prolonging the service life of the concrete and reducing the service life cycle maintenance cost of a concrete structure.
本发明属于建筑技术领域，本发明公开了一种钢纤维的改性方法及其在混凝土中的应用。本发明制备方法步骤为:称量聚烯丙基胺盐酸盐(PAH)溶解在磷酸缓冲盐溶液(PBS)中，并充分搅拌，得到特定浓度的PAH溶液，配置一定浓度的硅酸钠溶液备用；将钢纤维置于PAH溶液浸渍特定时间，随后取出并使用清水清洗；进一步将清洗完成后的钢纤维置于一定浓度硅酸钠(Na2SiO3)溶液浸渍处理特定时间；取出浸渍处理完成的钢纤维，使用清水进行清洗；步骤五：清洗完成后的钢纤维烘干至恒重，冷却至室温后备用。本发明不仅可以进一步提高钢纤维的品质，还能显著增强混凝土强度和耐久性，对延长混凝土的使用寿命，降低混凝土结构寿命周期维护成本具有十分积极的作用。
