The purpose of this study is to investigate the carbonation resistance of concrete using crushed clay bricks as coarse aggregate. In the experiment, crushed clay bricks is substitute for natural aggregate the rate of 0, 15, 30, 50% each. In order to find the effect of pozzolanic reactions as a subject of investigtion, the replacement rate of crushed clay bricks and compressive strength and carbonation depth after admixture have been investigated and analyzed by mixing 20% of blast-furnace slag and 10% of silica fume. As a result, it has been found that compressive strength in terms of physical performance decreases as the replacement rate of crushed clay bricks increases. However, at the case of replacement of mineral admixture and 30% of crushed clay bricks attained above compressive strength of OPC. As the replacement rate of crushed clay bricks increases, carbonation depth increases, and, for mineral admixture, the carbonation depth relatively increases with mixing than without.
