Abstract:
To satisfy the special requirements of self-compacting concrete construction in secondary lining construction of South-to-North Water Diversion Project, different pregnant liquors and functional ingredients were studied to analyze the liquidity, anti-segregability and filling property of concrete mixture. The mediating performance of pregnant liquor and functional ingredients was evaluated by different tests, such as slump test, slump divergence test, V-tunnel passing through test and T50 test, etc. It was proved that mediating pregnant liquor, fluidity agent, slow-released agent and slump-retaining agent could be used to prepare self-compacting concrete meeting the technical requirements.
