首都国际机场停车楼高性能混凝土施工技术

首都国际机场车楼工程中，采用Ｃ５０及Ｃ６０以上高性能混凝土，为最大限度减少水泥用量，降低水化热，减少收缩与裂缝，提高混凝土的性能，优选了有效成分含量高、质量好的水淬高炉矿渣磨细后单独掺用，

CONSTRUCTION TECHNOLOGY OF HIGH PERFORMANCE CONCRETE FOR THE CAPITAL INTERNATIONAL AIRPORT'S GARAGE BUILDING PROJECT

During construction of the Capital International Airport' s Garage Building project,the C50 and over C60 high performance concrete has been adopted for its construction.For the aim of 1,get a maximum reduction of cement comsumption 2,to lower the concrete's hydration heat 3,to reduce concrete's shrinkage and cracks,and 4,to promote concrete's performance,a high quality chilled blast furnace superfine slag has been adopted as an admixture.Furthermore,the adoption of some other minerals as the admixtures to get a high performance concrete has been carried out.As a result,these procedures and operations would have developed considerably the potential activity of concrete,and eventually the multiple performance and multiple function of concrete would have been improved and promoted.In conclusion a good result has been achieved in practice.
