摘要
将原状粉煤灰掺入机场道面用钢纤维混凝土中,研究了以原状粉煤灰等量取代、超量取代水泥及在水泥用量不变的条件下仅将其作为微细集料使用时对钢纤维混凝土性能的影响,探讨原状粉煤灰在机场道面用钢纤维混凝土中应用的可能性,以提高机场道面用钢纤维混凝土的力学性能,改善其内部结构,并降低一次性投资,为推广应用该项技术提供依据.
Raw fly ash was mixed into steel fiber concrete used for airport road pavement. The influence of using the raw fly ash as micro-fine aggregate in the cases of isometric and excess replacement of cement by the raw fly ash and addition of the fly ash without replacement of cement on the properties of the steel fiber concrete was investigated. The possibility of use of fly ash in the steel fiber concrete for airport road pave- ment was explored so as to improve the mechanical properties and its internal structure of the steel fiber concrete used {or airport road surface and reduce one-time investment. The basis for the application of fly ash in the steel fiber concrete is provided.
