Self-repairing concrete as well as preparation method and application thereof
The invention relates to the technical field of self-repairing concrete, in particular to self-repairing concrete and a preparation method and application thereof.The self-repairing concrete is prepared from cement, coarse aggregate, fine aggregate, modified self-repairing microcapsules, carbon fibers, a water reducing agent and water; the modified self-repairing microcapsule is obtained by performing argon plasma treatment modification on the self-repairing microcapsule; the self-repairing microcapsule is composed of a capsule core and a capsule wall; the capsule wall is ethyl cellulose; the capsule core is prepared from the following raw materials in parts by weight: 30 to 40 parts of silica powder, 20 to 30 parts of sodium silicate, 9 to 15 parts of limestone powder, 2.5 to 5 parts of nano silicon dioxide, 20 to 30 parts of basalt powder, 1 to 2 parts of microcrystalline cellulose, 1 to 2 parts of methyl cellulose and 2 to 3.5 parts of Tween 80; the self-repairing concrete is high in strength, excellent in self-repairing performance, stable in repairing effect and good in application effect.
本发明涉及自修复混凝土技术领域，具体涉及一种自修复混凝土及其制备方法和应用，自修复混凝土包括以下原料：水泥、粗骨料、细骨料、改性自修复微胶囊、碳纤维、减水剂、水；改性自修复微胶囊通过对自修复微胶囊进行氩气等离子体处理改性得到；自修复微胶囊由囊芯和囊壁组成；囊壁为乙基纤维素；囊芯包括以下重量份原料：硅微粉30‑40份、硅酸钠20‑30份、石灰石粉9‑15份、纳米二氧化硅2.5‑5份、玄武岩粉20‑30份、微晶纤维素1‑2份、甲基纤维素1‑2份、吐温80 2‑3.5份；本发明自修复混凝土强度高，同时自修复性能优良，修复效果稳定，应用效果好。
