以周大福工程C60高性能混凝土核心筒剪力墙的施工为背景,针对钢板墙墙体跨度大、钢筋密集的施工难点和易发裂缝的潜在危害,要求混凝土拌合物具有包裹性和流动性优异、黏度和内部温升值低等技术要点,进行原材和混凝土配合比的优化,制备出C60高性能混凝土,顺利进行核心筒钢板墙的浇筑施工,并且拆模后实体光滑平整没有裂缝出现。 Taking the construction of C60 high performance concrete core tube shear wall of CTF as the background, in view of the large spans of steel wall and the difficult construction of steel bar and the potential hazards of easy cracking, it is required that the concrete mixture has excellent encapsulation and flowability , Viscosity and internal temperature value is low and other technical points, to optimize the mix of raw materials and concrete to prepare C60 high performance concrete, the smooth construction of the core tube steel pouring wall, and the demolition of solid smooth body after no cracks appear.
