Waste aluminum scrap composite foamed slag concrete and preparation method thereof
The invention discloses waste aluminum scrap composite foamed slag concrete and a preparation method thereof, and belongs to the technical field of heat preservation and noise reduction concrete. The concrete is prepared from the following components in parts by mass: 0.3 to 0.7 part of waste aluminum skimmings, 10 to 50 parts of slag, 1.5 to 2.5 parts of a foaming agent, 7.5 to 12.5 parts of a foam stabilizer, 0.5 to 1.0 part of a water reducing agent and 100 parts of cement. The preparation method comprises the following steps: mixing the foaming agent and the foam stabilizer, and obtaining foam by using a foam maker; mixing and stirring slag, a water reducing agent, cement and waste aluminum skimmings to obtain a stirred material; mixing the foam into the stirred material, and stirring to obtain a mixture; and filling the mixture into a test mold, vibrating, hardening and shaping, and removing the test mold to obtain the waste aluminum scrap composite foamed slag concrete. The obtained waste aluminum scrap composite foamed slag concrete realizes solid waste utilization, and has the advantages of light weight, high bonding strength, good thermal insulation and noise reduction, greenness, environmental protection and the like.
本发明公开了一种废弃铝屑复合发泡矿渣混凝土及其制备方法，属于保温降噪混凝土技术领域；混凝土按质量份数计，其组分包括废弃铝屑0.3～0.7份、矿渣10～50份、发泡剂1.5～2.5份、稳泡剂7.5～12.5份、减水剂0.5～1.0份、水泥100份。其制备方法包括：将发泡剂和稳泡剂混合，利用发泡器得到泡沫；将矿渣、减水剂、水泥和废弃铝屑混合搅拌得到搅拌物；将泡沫混入搅拌物中，搅拌得到混合物；将混合物装入试模里，振捣并硬化定型，脱去试模后得到废弃铝屑复合发泡矿渣混凝土。本发明所得的废弃铝屑复合发泡矿渣混凝土实现了固废利用，具有材质轻、粘结强度高、保温降噪好，绿色环保等优点。
