摘要
汤浦水库面板混凝土掺用膨胀剂、减水剂、引气减水剂 ,具有较高的抗裂性能和一定的补偿收缩性能 ;在施工中采取了混凝土出模后覆盖塑料布 ,初凝后用草袋覆盖 ,终凝后流水或洒水养护等有效的防裂措施 ,取得良好效果。混凝土面板达到 6个月龄期时 ,经宏观调查 。
The concrete face slabs of Tangpu concrete face rockfill dam have well crack resistance and compensating shrinkage ability because of adding expansion agent, water reducing agent and aerated water-reducing agent in concrete. Some anti cracking measures are introduced during construction: first covering plastic film and covering straw bag after initial set of concrete, final sprinkling water after final set of concrete. These measures have made good effort,investagation shows no crack found in concrete face slabs after six month age.
