补偿收缩混凝土在超长大面积薄板工程中的应用

Application of Shrinkage-Compensating Concrete in Excessive-Length and Large-Area Thin Board Project

泰山广场二期工程主要结构形式为超长大面积无梁屋盖板的混凝土结构,经过合理设置混凝土膨胀加强带,采用缓凝型流化膨胀剂、粉煤灰、聚丙烯纤维复合掺加的方法,配制补偿收缩抗裂防渗混凝土,进行超长混凝土结构无缝施工,取得了良好的效果。

The main structural form of the second phase of Mount Tai Plaza is a concrete construcion characterized by excessive-length and large-area non-beam roofing board, the shrinkage-compensating and anti crack-leakage concrete made through rationally setting up concrete expansive reinforced belt and mixing slow hardening fluid-like expansive agent, fly ash and polypropylene fibre, thus a sound effect was achieved in the excessive-length jointless concrete construction.
