Abstract : 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, to 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
