Preparation and application method of self-repairing concrete material
The invention relates to the technical field of concrete materials, in particular to a preparation and application method of a self-repairing concrete material, overcomes the defects in the prior art, and comprises the following components in parts by weight: 300-500 parts of cement, 900-1400 parts of aggregate, 150-250 parts of water, 1-5 parts of microbial spores, 0.5-2 parts of nutrients, 5-15 parts of carbon nanohorn, 3-10 parts of nano clay and 0.5-2 parts of an additive. By adding the microbial spores, the carbon nanohorn and the nanoclay, the self-repairing function and the mechanical property of the concrete are improved, the impermeability, the freezing resistance and the chemical erosion resistance are enhanced, the service life is prolonged, the maintenance cost and the environmental influence are reduced by a self-repairing mechanism, the sustainable development requirement is met, and meanwhile, the self-repairing concrete has a good application prospect. The preparation method is simple, convenient and feasible, is suitable for large-scale application of industrial production, and is beneficial to technical popularization.
本发明涉及混凝土材料技术领域，尤其涉及一种自修复混凝土材料的制备及应用方法，解决了现有技术中存在的缺点，按重量份计包括以下成分：水泥300～500份、骨料900～1400份、水150～250份、微生物孢子1～5份、营养素0.5～2份、碳纳米角5～15份、纳米粘土3～10份、添加剂0.5～2份。本发明通过添加微生物孢子、碳纳米角和纳米粘土，实现了混凝土的自修复功能和力学性能提升，增强了抗渗性、抗冻性及化学侵蚀抵抗力，延长了使用寿命，自修复机制降低了维修成本和环境影响，符合可持续发展要求，同时，其制备方法简便易行，适用于工业生产规模化应用，有助于技术推广。
