某综合办公楼地下室和屋面采用补偿收缩混凝土结构自防水和聚氨脂涂膜双防水措施,地下结构、地上结构施工均采用补偿收缩混凝土超长结构连续施工技术。结合工程实际情况,通过保证膨胀剂限制膨胀率≥0.08%,优化混凝土配合比,合理设置膨胀加强带,在保证防水质量前提下,加快施工进度。
A composite office building basements and roof compensation and shrinkage of concrete structures using self-waterproofing and polyurethane coating double waterproofing measures, underground structures, above-ground structures are used to compensate for the construction of long-span continuous concrete construction technology. Combined with the actual situation of the project, by ensuring the expansive agent to limit the expansion rate ≥ 0.08%, optimizing the mix proportion of concrete and setting the expansion reinforcing belt reasonably, the construction schedule will be speeded up under the premise of ensuring the waterproof quality.
