上海保利大剧院工程中应用的大跨度弧形结构清水混凝土采用常规材料配制,满足了施工的和易性要求,同时满足清水混凝土的表观各项指标。着重强调了在大面积清水混凝土生产中,全过程质量风险点控制的重要性;详细介绍了对原材料的优选与组织、配合比执行中的用水量控制、生产过程中入泵坍落度及混凝土等待时间控制等。
The long-span arc structure clear water concrete used in the project of Shanghai Poly Grand Theater has been prepared by conventional materials to meet the requirements of workability and satisfy all the apparent indexes of clear water concrete. Emphasizes the importance of controlling the quality risk point in the whole process of the production of large-area fresh water concrete; introduces the optimization and organization of the raw materials, the control of the water consumption in the mix proportion implementation, the slump of the pump in the production process and the concrete Waiting time control and so on.
