摘要
基于实际工程,介绍了超长无缝大体积混凝土筏板施工技术,给出了筏板及加强带的混凝土配合比及温度裂缝的施工控制措施,并讨论了ZY膨胀剂在大体积混凝土施工中的作用机理及具体工程应用。
Based on a real building, some control measures of thermal crack in seamless excessive - lengthed matfoundation are suggested. The concrete mixture is listed in detail both format foundation and its strengthening joints, and the crack control strategies in concrete casting are put forward, The working mechanism of ZY - type expansive agent is analyzed, and its practical applying is outlined.
