Abstract |
This study evaluated the carbonation resistance of concrete with high-functional exterior wall paint. After applying the high-functional exterior paint, accelerated weathering test (KS M 6010) and accelerated carbonation test (KS F 2584) were conducted. As a result of the study, it was confirmed that the developed high-functional exterior wall paint significantly enhance the carbonation resistance when applied to concrete, thus improving the durability of concrete structure. Additionally, to examine the weathering resistance deterioration due to external factors (such as UV rays, moisture, and heat) when applied to actual buildings, the carbonation depth was measured after the accelerated weathering test. The results confirmed that even after 1,200 hours of harsh accelerated weathering conditions, the carbonation resistance did not significantly decrease.
