高性能与自密实混凝土技术在琴台大剧院中的应用

Application of High Performance and Self-compacting Concrete Technique to Qintai Great Theater

作为第八届中国艺术节的主会场,琴台大剧院工程是国家的重点工程.由于工程的复杂性,使得超长、超大面积及大体积混凝土是本工程结构的重要特点,其裂缝控制、混凝土的耐久性能成为了工程施工的重点与难点.为此,针对工程中所选用的材料情况,通过试验研究,制定出了能较好满足工程实际所需的高性能与自密实混凝土配合方案与施工方法,为工程质量的确保提供了技术上的支持.

According to the planning of the Ancient Guqin Terrace area construction, the ancient Guqin Terrace has been totally modified and perfected by Wuhan Government. Because of the complexity of the project, super long, super-large area and massive concrete are important features of this project structure. Cracking controlling and durability of concrete construction have become the emphases and difficulties of this project. For this purpose, taking into account the chosen materials, a high-performance and self-compacting concrete mix scheme and construction methods are developed; that can meet the practical requirements, and provide technical support to the quality and safety of this project.
