Abstract：
In construction of Beijing New Airport Terminal and General Transfer Center project, to overcome the difficulty that C40P10 concrete batching plant is far from the construction site, slump-retaining mother liquor, sodium gluconate and sustained release agent were prepared. Slump constant, slump flow and setting time were tested to evaluate the influence of mother liquor and functional ingredients on long-time slump retaining performance of mixture. It was shown that the C40P10 concrete prepared with dewatering mother liquor, regulating mother liquor, slump retaining mother liquor, sustained release agent and sodium gluconate could satisfy the technique requirements.
