| titleOfInvention | Composition for centrifugal compaction of concrete |
| abstract | (57) [Summary] [Purpose] To improve the centrifugal compaction of concrete and improve productivity and product quality. A composition for centrifugal compaction of concrete, which comprises an acrylamide polymer having a molecular weight of 100,000 to 1,000,000 and an oxycarboxylic acid and / or sugar. [Effect] The acrylamide polymer effectively finely aggregates cement components and fine particles, and accelerates dehydration of excess water by centrifugal force. In addition, oxycarboxylic acid (or salt) and saccharides improve workability while maintaining the fluidity (workability) of concrete, and the synergistic effect of both components improves remarkably excellent centrifugal compaction. The effect is obtained. As a result, the centrifugal compaction property of concrete is improved, the pipe manufacturing time can be shortened, and the product quality is improved by reducing the floating caused by poor dehydration, and further the inner surface finish and workability are improved.
