Micro-nano bubble water tailing concrete and preparation method thereof
The invention relates to micro-nano bubble water tailing concrete and a preparation method thereof, and relates to the technical field of building materials. The micro-nano bubble water tailing concrete is prepared from the following raw materials in parts by weight: 130 to 170 parts of micro-nano bubble water, 310 to 410 parts of a cementing material, 650 to 850 parts of fine aggregate, 880 to 1000 parts of coarse aggregate and 1 to 3 parts of a water reducing agent, the fine aggregate comprises modified tailing microspheres and natural sand, the modified tailing microspheres account for 40-60% of the total mass of the fine aggregate, and the particle size of the modified tailing microspheres is 0-5 mm; the coarse aggregate comprises modified tailing particles and stones, the modified tailing particles account for 60%-70% of the mass of the coarse aggregate, and the particle size of the modified tailing particles is 5-16 mm; the modified tailing microspheres and the modified tailing particles are prepared by stirring and screening raw materials including tailing micro powder, a binding material, water and tridecafluorooctyltrimethoxysilane, and the modified tailing microspheres and the modified tailing particles are obtained according to different particle sizes after screening. The method has the effect of improving the workability of the concrete on the basis of not influencing the strength of the concrete.
本申请涉及一种微纳米气泡水尾矿混凝土及其制备方法，涉及建筑材料技术领域。微纳米气泡水尾矿混凝土由包括如下重量份的原料制成：微纳米气泡水130‑170份，胶凝材料310‑410份，细骨料650‑850份，粗骨料880‑1000份，减水剂1‑3份；细骨料包括改性尾矿微球和天然砂，改性尾矿微球占细骨料总质量的40‑60%，改性尾矿微球的粒径为0‑5mm；粗骨料包括改性尾矿颗粒和石，改性尾矿微颗粒占粗骨料质量的60%‑70%，改性尾矿颗粒的粒径为5‑16mm；改性尾矿微球和改性尾矿颗粒由包括尾矿微粉、胶凝材料、水和十三氟辛基三甲氧基硅烷的原料经过搅拌、筛分工艺制得，筛分后以粒径不同分别得到改性尾矿微球和改性尾矿颗粒。本申请具有在不影响混凝土强度的基础上提高混凝土工作性的效果。
