Abstract
We simultaneously studied increase in carbonation inhibition effect by densification of the concrete structure due to pozzolanic reaction and decrease in the same due to consumption of Ca(OH)2, and we attempted to shed light on the effect of mixing fly ash on the durability of concrete with the help of accelerated carbonation test. As a result, In the concrete having the same water-cement ratio, we studied carbonation inhibition effect by combining the effect of consumption of Ca(OH)2 due to pozzolanic reaction of fly ash and increase in compressive strength. Based on the compressive strength of concrete and Ca(OH)2 amount, we could demonstrate the carbonation inhibition effect of fly ash mixed concrete.
