| Abstract: | 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. |
