摘要
208m高的杨浦大桥主桥塔对混凝土收缩、徐变有着特定的要求,通过试验探索,确定了高性能、高泵程混凝土的配合比。
As for the 208m high tower of Yangpu Main bridge, certain requirements exist in concrete shrinkage and creepage. After a series of researches and tests, the mix ratio is determined for the high-performance concrete adapted to high pump lift.
