大体积混凝土是混凝土结构物最小尺寸不小于1 m的混凝土,或预计会因混凝土中胶凝材料水化引起的温度变化和收缩导致有害裂缝产生的混凝土。随着建筑高度的增长和体量的增大,大体积混凝土的应用越来越广泛,其浇筑施工已成为建筑施工的重点和难点。某超高层建筑的总建筑面积为139 743.67 m2,地下3层,地上裙楼5层,主楼24层,建筑层高5.4 m,建筑高度为
Mass concrete is concrete with a minimum size of 1 m for concrete structures or concrete that is expected to produce harmful cracks due to temperature changes and shrinkage caused by hydration of cementitious materials in concrete. With the increase of building height and volume, the application of mass concrete is more and more widely. The pouring construction has become the key and difficult point of building construction. A super high-rise building with a total construction area of 139 743.67 m2, 3 underground floors, 5 floors above ground podium, 24 floors of the main building, building height of 5.4 m, building height
