Nano composite material for filling micropores of concrete structure and preparation method and application of nano composite material
The invention relates to a nano composite material for filling micropores of a concrete structure and a preparation method and application of the nano composite material, and belongs to the technicalfield of concrete structure performance improvement. The nano aqueous solution prepared by the method has ultra-low viscosity, high permeability and high nano activity and can be quickly migrated andpermeated into concrete, and the compactness of the concrete from the surface layer to the interior is improved so that the permeation resistance, cracking resistance, surface strength, hardness and comprehensive durability of a concrete structure are improved, and the acid and alkali resistance, freeze-thaw resistance, skid resistance, ion corrosion resistance and the like of the concrete are improved. The nano aqueous solution prepared by the method can be used for repairing and maintaining concrete structures with pores smaller than 0.1 mm in different service environments.
本发明涉及一种用于填充混凝土结构微孔的纳米复合材料及其制备方法和应用，属于混凝土结构性能改进技术领域。本发明制备的纳米水溶液以其超低粘度的高渗透性和高纳米活性，可快速迁移、渗透到混凝土内部，提高混凝土表层到内部的致密性，从而提高混凝土结构的抗渗透性、抗开裂性、表面强度、硬度及综合耐久性，改善混凝土耐酸碱性、耐冻融性、抗滑性能和抗离子侵蚀性等。本发明制备的纳米水溶液，实现可对处于不同服役环境下具有小于0.1mm孔隙的混凝土结构进行修复和养护。
