随着建筑技术的发展,高层、超高层建筑中大量使用到高强、超高强混凝土,混凝土的配置及其超高泵送技术是其中的重要一环。上海环球金融中心工程中运用了大体积混凝土施工综合技术,直径达100m、厚4.5m、总方量达2.89万m~3的主楼底板混凝土在42h内一次连续浇筑完成。在广州西塔的建设过程中,建设者积极组织开展各种试验和科技攻关,将C100高性能混凝土一次成功泵送到333m高度。在京基100大厦项目中,建设者完成了
With the development of construction technology, high-strength and ultra-high-rise buildings are widely used in high-strength and ultra-high-strength concrete, and the configuration of concrete and its ultra-high pumping technology are an important part. Shanghai World Financial Center project uses mass concrete construction technology, the diameter of 100m, thickness 4.5m, the total square amount of 28,900 m 3 of the main building floor concrete in a 42h continuous pouring completed. During the construction of Guangzhou West Tower, builders actively organized various experiments and scientific research to successfully pump C100 high-performance concrete to a height of 333m once. In the Jingji 100 building project, the builders completed
