Fabricated recycled aggregate lightweight concrete externally-hung wallboard and preparation method thereof
The invention discloses a fabricated recycled aggregate lightweight concrete externally-hung wallboard, which is used for a steel structure box building and is prepared from the following raw auxiliary materials in parts by weight: 300 to 500 parts of cement, 50 to 150 parts of mineral powder, 200 to 300 parts of ceramsite, 200 to 400 parts of fine aggregate, 300 to 500 parts of coarse aggregate,200 to 400 parts of furnace slag, 8 to 15 parts of a water reducing agent and 160 to 190 parts of water. According to the fabricated recycled aggregate lightweight concrete externally-hung wallboard for the steel structure box building, a large amount of municipal construction waste recycled aggregate and thermal power plant waste slag is used, a large amount of municipal construction waste and industrial solid waste can be consumed; as the slag has many gaps and is light in weight, the thickness of the externally-hung wallboard is 100 to 200 mm, the maximum size of the length and the width is4000 mm, the volume weight of the concrete is 1600-1900 kg/m<3>, the strength is 30-36 MPa, the requirements of lightweight concrete are met, the strength meets the requirements of C30 strength gradeconcrete, and as an externally-hung wallboard, the self weight can be reduced, and the structural safety is improved.
本发明公开一种装配式再生骨料轻质混凝土外挂墙板，用于钢结构盒子建筑，它是由如下重量配比的原辅料制备而成：水泥300‑500份，矿粉50‑150份，陶粒200‑300份，细骨料200‑400份，粗骨料300‑500份，炉渣200‑400份，减水剂8‑15份，水160‑190份。一种用于钢结构盒子建筑的装配式再生骨料轻质混凝土外挂墙板，大量使用城市建筑垃圾再生骨料，和火电厂废弃炉渣，可以大量消耗城市建筑垃圾和工业固废，由于炉渣空隙多、质量轻，此外挂墙板厚度为100‑200mm，长宽最大尺寸为4000mm，混凝土容重在1600‑1900kg/m3之间，强度在30‑36MPa之间，满足轻质混凝土要求，强度满足C30强度等级混凝土要求，作为外挂墙板，可以减轻自重，增加了结构安全性。
