Investigations on Durability of High-Volume Fly Ash Concrete
The durability and strength characteristics of high-volume fly ash concrete were studied in order to utilize fly ash, an industrial by-product from coal fired thermal power plants, as a typical admixture for concrete. The results of this study are as follows: (1) The strength development of high-volume fly ash concrete is higher than that of conventional concrete; (2) There is an optimum mixing ratio of fly ash, in which the compressive strength reaches a maximum level; (3) Freezing and thawing resistance of high-volume fly ash concrete is almost the same as that of conventional concrete; (4) Abrasion resistance, durability in marine environment, and water-tightness are improved by the use of high-volume fly ash; and (5) Adiabatic temperature rise can be reduced compared with that of concrete without fly ash.
