3D printable UHPC based on regenerated glass sand, and preparation method thereof
The invention relates to the field of building 3D printing and waste recycling, particularly to 3D printable UHPC based on regenerated glass sand, and a preparation method thereof. The 3D printable UHPC based on the recycled glass sand comprises the following components in parts by weight: 700 to 900 parts of cement, 150 to 270 parts of silica fume, 150 to 250 parts of fly ash, 800 to 1000 parts of regenerated glass sand, 8 to 19 parts of steel fiber, 9.2 to 18.1 parts of a water reducing agent, 3.9 to 11.5 parts of nano clay, 0.8 to 4.7 parts of cellulose, and 150 to 350 parts of water. The 3D printable UHPC based on regenerated glass sand overcomes the defects of low mechanical properties and durability of the existing building 3D printing material, and uses regenerated glass sand, silica fume and fly ash, so that resource recycling of wastes is realized, and the 3D printing UHPC has high environmental benefits and social benefits.
本发明涉及建筑3D打印及废弃物资源化领域，尤其涉及一种基于再生玻璃砂的可3D打印UHPC及制备方法。该基于再生玻璃砂的可3D打印UHPC，以重量份计，包括以下组分：水泥：700‑900份；硅灰：150‑270份；粉煤灰：150‑250份；再生玻璃砂：800‑1000份；钢纤维：8‑19份；减水剂：9.2‑18.1份；纳米黏土：3.9‑11.5份；纤维素：0.8‑4.7份；水：150‑350份。该基于再生玻璃砂的可3D打印UHPC克服了现有建筑3D打印材料力学性能和耐久性能低的缺陷。同时，该3D打印UHPC使用了再生玻璃砂、硅灰、粉煤灰，实现了废弃物的资源再生利用，具有较高的环境效益和社会效益。
