Abstract |
A comprehensive understanding of the effects of carbonation on the chemical and physical properties of concrete remains limited. This study investigates the impact of carbonation on concrete compressive strength through both experimental analysis and a review of existing literature. Representative mortar mixtures were subjected to two carbonation conditions: long-term carbonation (continuous exposure from the first day of curing) and short-term carbonation curing (applied after the first day of sealed curing, followed by 24 or 72 hours of intensive carbonation and subsequent underwater curing). Compressive strength was then measured, and the results were analyzed in conjunction with previous studies to identify trends. Based on these findings, the mechanism underlying the effects of carbonation on the compressive strength of concrete are discussed.
