BINDER COMPOSITION COMPRISING FLY ASH AND HIGH-STRENGTH BINDER PREPARED THEREFROM

摘要

The present invention relates to a binder composition including fly ash and a high strength binder prepared therefrom. According to the present invention, a specific content of formate is mixed with a binder obtained by mixing fly ash which is an industrial by-product and quicklime (CaO) to form a C-S-H bond, AFm phase, and katoite and calcite crystals in a binder after curing, and to increase a ratio thereof at the same time, thereby reducing pores and enhancing the initial strength and the long-term strength over time. The binder of the present invention may exhibit the strength the same as or higher than that of a cement-based binder, thereby being used as a binder substituted for the conventional cement-based binder.
