Abstract
Six Reinforced Concrete (RC) columns composed of Treated Recycled Concrete Aggregate (TRCA) and Natural Aggregate (NA) were subjected to experimental and theoretical analyses to ascertain their axial compressive behavior. The method of soaking recyclable aggregate in a NAOH solution was then employed to treat it. The TRCA was subjected to replacement ratios of 20%, 40%, 60%, 80%, and 100% relative to the total weight of NA. The dimensions of the column were 700 mm, 150 mm, and 150 mm, respectively. The column was reinforced with steel of varying diameters. The transverse reinforcement was 6 mm in diameter, whereas the longitudinal reinforcement was 8 mm in diameter. To examine the axial compressive behavior of the columns, the final load values obtained from the static tests were revealed. The measured axial capacity of the columns was then compared with the theoretical values derived from the ACI codes. The incorporation of TRCA contents was observed to enhance the columns' axial capacity, as evidenced by the experimental results. However, the computed theoretical values were found to be more conservative than the experimental observations. This suggests that there is no risk involved in using TRCA and NA-TRCA columns in construction.
