Foam concrete taking tunnel hole slag as raw material and preparation process of foam concrete
The invention discloses foam concrete taking tunnel hole slag as a raw material and a preparation process of the foam concrete, and belongs to the technical field of hole slag utilization. Comprising the following components: 400-500 parts of cement, 390-530 parts of cave slag machine-made sand, 65-75 parts of stone powder, 100-115 parts of fly ash, 15-45 parts of polypropylene fiber, 5-8 parts of a foam stabilizer, 1-2 parts of a water reducing agent, 5-10 parts of a foaming agent and 200-250 parts of water. According to the process provided by the invention, the polypropylene fiber with acid and alkali resistance is added to prepare the mixture of the foaming agent and the foam stabilizer, so that the prepared foam concrete has the advantages of light weight, high strength, proper pore size, uniform distribution, sound insulation and durability; the tunnel hole slag is prepared into the foam concrete through a certain process, a new direction is provided for utilization of the hole slag, the application range is wider, the value is higher, the treatment problem of the hole slag can be effectively solved, and the economic benefit of engineering can be increased; and the preparation process is simple and easy to operate and low in pollution, and conforms to the concept of green sustainable development.
本发明公开了一种以隧道洞渣为原料的泡沫混凝土及其制备工艺，属于洞渣利用技术领域，一种以隧道洞渣为原料的泡沫混凝土，包括如下组分：水泥400‑500份、洞渣机制砂390‑530份、石粉65‑75份、粉煤灰100‑115份、聚丙烯纤维15‑45份、稳泡剂5‑8份、减水剂1‑2份、发泡剂5‑10份和水200‑250份。本发明提供的工艺通过添加具有耐酸碱特性的聚丙烯纤维、制备发泡剂和稳泡剂混合物，使制备的泡沫混凝土，具有轻质高强、气孔大小适宜、分布均匀、隔音、耐久的优点；通过一定的工艺将隧道洞渣制备成泡沫混凝土，为洞渣的利用提供了新的方向，应用范围更广，价值更高，不仅可以有效解决洞渣的处理问题，还可以增加工程的经济效益；制备工艺简单易操作，污染小，符合绿色可持续发展的理念。
