- Abstract
- The purpose of this experimental study is to evaluate flexural behavior of reinforced concrete beams using Recycle Coarse Aggregate (RCA) with the Minimum Reinforcement Ratio (M.R.R) specified in KBC 2009 code equation. In the experiment, nine beam specimens fixed with ρ=0.00352 and design compressive strength of concrete (32MPa) were substituted with 0%, 30%, 50% of RCA and were used with 100%, 75%, 50% of M.R.R. The test value compared with the theoretical value has enough safety margin although theoretical value compared with the code calculation value has not enough safety margin when it is M.R.R of 75% and 50%. Howerever, theoretical value compared with code calculation value has enough safety margin at the M.R.R of 100%.
