Cement-free high-performance concrete repairing material and preparation method thereof
The invention discloses a cement-free high-performance concrete repairing material and a preparation method thereof, and relates to the technical field of concrete. The concrete repairing material is prepared from the following raw materials: a low-carbon cementing material, tailing sand, water, a water reducing agent, polyvinyl alcohol fibers and waste rubber powder, and activated coal gangue and activated fly ash can be further added into the low-carbon cementing material to further improve the performance. Various industrial solid waste components are used, so that resources are recycled, consumption of natural resources is reduced, no cement component is added, emission of carbon dioxide and other gas pollutants caused by cement production is reduced, the energy-saving and carbon-reducing benefits are remarkable, and the prepared concrete repairing material is excellent in performance, good in durability and good in application prospect. Meanwhile, the preparation method has the advantage of simplicity, and has important popularization and application values in the field of concrete repairing materials.
本发明公开了一种无水泥高性能混凝土修补材料及其制备方法，涉及混凝土技术领域。本发明的混凝土修补材料原料包括：低碳胶凝材料、尾矿砂、水、减水剂、聚乙烯醇纤维和废橡胶粉，还可以进一步在低碳胶凝材料中添加活化煤矸石及活化粉煤灰组分进一步提升性能。本发明使用各类工业固废组分，使得资源循环利用，减少了天然资源的消耗，没有水泥组分的添加，降低了水泥生产造成的二氧化碳及其他气体污染物的排放，节能降碳效益显著，制备得到的混凝土修补材料性能优异、耐久性好，同时具有制备方法简单的优势，在混凝土修补材料领域中具有重要的推广应用价值。
