| 中文摘要: |
| 集料含水率对于混凝土水胶比波动有十分重要的影响，砂石料中水含量变化将会影响设计配合比在施工中的实现。文章对苏通大桥集料的含水率进行测定，研究典型天气条件下含水量分布和变化情况，提出调整不同天气条件下砂石料含水率方法。 |
| 英文摘要: |
| Water content of aggregate show an important effect on the water binder ration of concrete. The change of water content in aggregate will effect the realization of design mix proportion in the construction. The water content distributing and changing in representative weather has been studied by the water content measure of Sutong bridge. The water content adjustment way of aggregate is proposed in different weather. |
