摘要
Abstract
The Longkaikou Hydropower Station locates at a hot, dry and windy region, and the dolomite is abundantly used as concrete aggregate for the first time in China. The construction quality of RCC is difficult to control. A series of quality control measures are implemented in key construction processes of mix proportion determination, concrete transportation, spreading and leveling and compacted, interlayer bonding control and distorted concrete construction. The powder content of artificial sand is controlled at 17% and the content of micronized powder is not less than 5%. The concrete transportation to placement surface is mainly taken by trucks and supplemented by chute shafts and belt conveyors. The compaction of concrete is controlled by digital dam system. These measures ensure the rapid and continue large-surface concrete placement and the quality of concrete meeting design requirements.关键词
