Comparison of carbonation resistance and uniformity of SCC and CC core samples

Abstract

The purpose of this research was to compare self-compacting concrete (SCC) and conventional concrete (CC), which are used in beams with dense reinforcement, in terms of their carbonation resistance. It was observed that, in both air and moist curing environments, SCC had less carbonation depth than CC and the carbonation depths of both SCC and CC samples stored under moist curing were less than those of samples undergoing air curing. The experiments also showed that, regardless of the type of concrete, carbonation depth decreased with increasing concrete strength class. Furthermore, the study showed that beams produced from SCC were more uniform than CC beams. Consequently, instead of CC, SCC can be used to produce any reinforced concrete components in order to provide increased carbonation resistance and uniformity. The findings of this study may thus lead to increased usage of SCC in construction sites.
