摘要
首都国际机场新航站楼主体结构设计为C6O及C65高性能混凝土。该工程施工过程中 ,通过控制水泥用量 ,掺加优质细掺料和膨胀剂 ,控制出机温度与温差 ,加强早期养护等措施 ,有效地防止了由于温度应力和收缩而引起的裂缝。
The design and construction of the new Aviation Building project of Beijing Capital Airport,has been adopted of C60 and C65 high performance concrete.During its construction,there are a number of effective measures applied namely:1,cement volume control,2,application of high-quality fine-adimixture and expansion agent,3,control of concrete pouring temperature and its differential-temperature.Therefore,cracks caused by temperature stress and concrete shrinkage are effectively eliminated.
