Anti-erosion concrete and preparation method thereof
The invention discloses anti-erosion concrete which is characterized by comprising the following components in parts by weight: 5-20 parts of plant ash, 4-15 parts of wet carbonized red mud, 0.1-5 parts of biomass derived carbon dots, 10-20 parts of cement, 25-45 parts of porous aggregate, 20-40 parts of reclaimed sand, 0.2-6 parts of an additive and 15-35 parts of water, many active molecules in the biomass derived carbon dots are accumulated on the surface of steel through Van der Waals force or other intermolecular kinetic potential, the cathodic reaction is inhibited in the early stage of corrosion, the anodic reaction is inhibited in the later stage of corrosion, and finally an adsorption film is formed on the surface of the steel bar to relieve corrosion of the steel bar. Therefore, a protective layer formed on the surface of the reinforcing steel bar by the wet-type carbonized red mud, the plant ash and other rubber materials is enhanced, the three components cooperate with each other to provide the protective layer for the reinforcing steel bar, and corrosion of the reinforcing steel bar is relieved.
本发明公开了一种抗侵蚀混凝土，其特征在于，包括以下重量份的组分：植物灰5‑20份、湿式碳化赤泥4‑15份、生物质衍生碳点0.1‑5份、水泥10‑20份、多孔骨料25‑45份、再生砂20‑40份、外加剂0.2‑6份以及水15‑35份；生物质衍生碳点中许多活性分子通过范德华力或其他分子间作动势积聚在钢铁表面，在腐蚀早期抑制阴极反应，在腐蚀后期抑制阳极反应，最终钢筋表面形成一层吸附膜来缓解钢筋的腐蚀，从而增强湿式碳化赤泥、植物灰等胶材在钢筋表面形成的保护层，三者相互协同来对钢筋提供保护层，缓解钢筋腐蚀的发生。
