Fabricated recycled aggregate lightweight concrete prefabricated stair
The invention discloses a fabricated recycled aggregate lightweight concrete prefabricated stair. The fabricated recycled aggregate lightweight concrete prefabricated stair is composed of cement, mineral powder, ceramsite, fine aggregate, coarse aggregate, slag, a water reducing agent and water. Recycled aggregate concrete and lightweight concrete are combined, so the lightweight concrete requirement is met, the strength meets the C30 strength grade concrete requirement, and the fabricated recycled aggregate lightweight concrete prefabricated stair serving as a prefabricated lightweight concrete stair reduces the dead weight of a structure and improves the structural safety; and the fabricated recycled aggregate lightweight concrete prefabricated stair is a product of building industrialization, can be designed in a standardized mode, can be prefabricated in a factory and installed on site, does not need wet operation, is simple in procedure and high in efficiency, can absorb and consume a large amount of industrial wastes and construction wastes, has environmental protection significance and has good use prospects.
本发明公开了一种装配式再生骨料轻质混凝土预制楼梯，该装配式再生骨料轻质混凝土预制楼梯是由水泥、矿粉、陶粒、细骨料、粗骨料、炉渣、减水剂和水组成；本发明所述的一种装配式再生骨料轻质混凝土预制楼梯，通过将再生骨料混凝土和轻质混凝土结合，在满足轻质混凝土要求，强度满足C30强度等级混凝土要求，作为预制轻质混凝土楼梯，使得减轻了结构物自重，增加了结构安全性；装配式再生骨料轻质混凝土预制楼梯是建筑工业化的产物，可以标准化设计，在工厂预制完成，现场安装，无需湿作业，工序简单，效率高，同时能够大量吸收、消耗工业废弃物和建筑垃圾，更具环保意义，具有良好使用前景。
