Abstract:
The purpose of this research was to study the penetrating characteristics of chloride ions into fly ash concrete and the corrosion of steel reinforcement in concrete, where some parts of fine and coarse aggregates were replaced by fly ash . Several tests such as compressive strength test, chloride penetration test and corrosion diagnosis of steel reinforcement in concrete were performed. Through these tests, the physical properties and durability of fly ash concrete against aggressive environments have been studied.
