In case of using fly ash as some substitutes of cement, it is possible for us to improve durability through the improvement of liquidity and enhancement of water-tightness according to the effect by the ball bearing of mortar and concrete. It is widely used because it is very effective of decreasing the crack of concrete and improving the long-time strength through the decrease of heat of hydration, etc. However, it is severe in quality variation by the use of reckless substitutes, and it has large congelation retard, so there are disadvantages like the deterioration of performance on mortar and concrete due to the decrease of early strength. Accordingly, as a result of analyzing the strength, characteristics of congelation, and heat of hydration, etc. in order to examine the engineering properties of mortar using fly ash with high fineness in this study, this researcher could get excellent performance on the improvement of early strength and characteristics of heat of hydration according to the acceleration of congelation by the high fineness.
