Full-hole slag aggregate concrete and preparation method thereof
The invention discloses whole hole slag aggregate concrete, which is prepared from the following raw materials in parts by weight: 800 to 1100 parts of hole slag coarse aggregate, 700 to 950 parts of hole slag fine aggregate, 280 to 420 parts of cement, 50 to 150 parts of mineral admixture, 2 to 5 parts of water reducing agent and 130 to 180 parts of water. The invention also discloses a preparation method of the full-hole slag aggregate concrete. According to the invention, the igneous rock powder produced by the tunnel hole slag is doped with silica fume and an active agent to replace fly ash, and the igneous rock powder produced by the tunnel hole slag, the machine-made aggregate and the high-quality machine-made sand are fully and efficiently utilized to prepare the whole hole slag product concrete; and the prepared full-hole slag high-performance concrete has excellent working performance, mechanical performance and durability, not only is the use of the natural gravel material and the fly ash saved and the engineering cost reduced, but also the problem of treatment of the tunnel hole slag is solved, and the engineering efficiency is improved.
本发明公开了一种全洞渣骨料混凝土，包括以下按重量份数配比的原料：洞渣粗骨料800份‑1100份，洞渣细骨料700份‑950份，水泥280份‑420份，矿物掺合料50份‑150份，减水剂2份‑5份，水130份‑180份。本发明还公开了一种全洞渣骨料混凝土的制备方法。本发明通过将隧道洞渣生产的火成岩石粉掺加硅灰和活性剂替代粉煤灰，充分高效利用隧道洞渣生产的火成岩石粉、机制骨料和精品机制砂，进行全洞渣制品混凝土配制，并且制备得到的全洞渣高性能混凝土具有优异的工作性能、力学性能和耐久性能，不仅节约了天然砂石料和粉煤灰的使用，降低了工程成本，还解决了隧道洞渣的处理难题，提高了工程效率。
