Abstract:
This paper presents the development of a new type of high-performance concrete, a highly-flowable steel fiber-reinforced concrete. This concrete has superior characteristics, such as high flowability and adequate segregation resistance, retention of high flowability, and high-strength at an early age. In order to obtain such properties, it is necessary to use high early-strength portland cement, fly ash, a viscosity agent, an air entraining and a high-range water reducing admixture. Moreover, partially replacing cement with fly ash is found to be an effective method to improve the retention of slump flow. Pumpability of highly-flowable steel fiber-reinforced concrete containing fly ash has also been evaluated from the results of the experimental pumping tests.
