High-temperature-resistant aerogel mortar composite recycled concrete and preparation method thereof
The invention discloses high-temperature-resistant aerogel mortar composite recycled concrete and a preparation method thereof.The high-temperature-resistant aerogel mortar composite recycled concrete is prepared from recycled concrete containing cement, fly ash, recycled coarse aggregate, river sand, a water reducing agent and water and aerogel mortar containing cement, river sand, SiO2 aerogel, a KH-550 reagent, the water reducing agent and the water, the recycled concrete and the aerogel mortar are combined in an integrated forming mode, and the high-temperature-resistant aerogel mortar composite recycled concrete is prepared. Waste material resources are fully utilized, dependence on natural resources is reduced, the high-temperature resistance of the recycled concrete is improved, and the recycled concrete has wide application prospects.
本发明公开了一种耐高温的气凝胶砂浆复合再生混凝土及其制备方法，包括：包含水泥、粉煤灰、再生粗骨料、河砂、减水剂和水的再生混凝土和包含水泥、河砂、SiO2气凝胶、KH‑550试剂、减水剂和水的气凝胶砂浆，通过一体成型的方式将二者结合，充分利用废弃材料资源，减少对天然资源的依赖，提升再生混凝土的耐高温性能，具有广阔的应用前景。
