武汉中心工程低热低收缩高强自密实混凝土制备及应用

Preparation and Application of Low-heat and Low-shrinkage High-strength Self-compacting Concrete for Wuhan Center Project

根据武汉中心工程对混凝土性能的需求,首先通过降低混凝土水化热、提高混凝土密实度、降低混凝土自收缩、提高混凝土泵送性能的研究,制备出低热低收缩高强自密实混凝土,最后结合武汉中心工程特点,通过优化结构形式、采取合理的施工技术,保证混凝土的施工质量。

In this paper,the authors analyze the performance of concrete according to Wuhan Center project. Firstly,the low-heat and low-shrinkage high-strength self-compacting concrete is prepared by reducing the concrete hydration heat, improving the concrete compactness, reducing autogenous shrinkage of concrete,improving the concrete pumping performance. Finally,based on the characteristics of Wuhan Center project,the construction quality of concrete is ensured by the optimization of structural form and reasonable construction technology.
