Self-repairing concrete as well as preparation method and application thereof
The invention provides self-repairing concrete as well as a preparation method and application thereof, and belongs to the technical field of concrete. The concrete comprises the following components,by weight: 150-200 parts of cement, 100-200 parts of sand, 50-80 parts of gravels, 10-15 parts of polyvinyl alcohol, 30-50 parts of fly ash, 7-9 parts of sodium alginate, 8-16 parts of regenerated PPshort fibers, 15-20 parts of a water reducing agent, 2-5 parts of hydroxymethyl cellulose, 5-10 parts of anti-cracking fibers, 4-7 parts of silica fume, 7-9 parts of sodium silicate, 13-15 parts of deionized water and 100-150 parts of water. A net structure is formed between the regenerated PP short fibers and the anti-cracking fibers, and cracks can be effectively reduced.
本发明提供了一种自修复混凝土及其制备方法与应用，属于混凝土技术领域。包括以下重量份数的组分：水泥150～200份，砂100～200份，碎石50～80份，聚乙烯醇10～15份，粉煤灰30～50份，海藻酸钠7～9份，再生PP短纤维8～16份，减水剂15～20份，羟甲基纤维素2～5份，抗裂纤维5～10份，微硅粉4～7份，硅酸钠7～9份，去离子水13～15份，水100～150份。本发明再生PP短纤维和抗裂纤维之间构成网状结构，能够有效地减少裂缝的产生。
