ABSTRACT
In the previous research, the authors conducted comprehensive research on 蠒 14 and 蠒 16 mm with various amounts of Olive Oil Mill Wastewater (OOW) and Brine Wastewater (BW). However, the author extends their research to include the effect of strength, and bond stress on the small size of steel bars such as 蠒 6, 蠒 8, 蠒 10, and 蠒 12 mm. The pull-out test determines the bond stress, with the same percentages of 2.5, 5.0, 7.5, 10, and 15 BW and OOW. Although there was a previous study of this feature, it would not address the evaluation of the performance of thin reinforcing bars including 12, 10, 8, and 6 mm, which were normally used in reinforced concrete elements, and to make things clearer. Pull-out tests were conducted on the specimens with an added percentage, as mentioned above, based on the weight of water for each, the size of the cylinders 150 x 300 mm, and the anchorage zone of 200 mm used. The results of the test carried out using the pull-out test showed that the bonding strength for thin diameters is higher than that for large diameters. When adding OOW, the bonding strength is good, but it is less than that of the reference samples, as it reached diameters of 6 mm (3.01 MPa), 8 mm (2.63 MPa), 10 mm (6.17 MPa), and for 12 mm (6.33 MPa), which is less than the reference samples by about 35% for diameters 6 and 8, and 8% for diameters 10 and 12 mm. When adding BW, the bonding strength reached for diameter 6 (3.66 MPa), diameter 8 (2.66 MPa), diameter 10 (6.41 MPa), and diameter 12 (6.58 MPa), which is less than the reference samples by about 10.5% for diameters 6 and 8, and 4% for diameters 10 and 12 mm. These results are for the best-added ratios, which gave us the best compressive and bending strengths, which are 7.5% and 10% for OOW and BW, respectively. Note that the diameters 6 and 8 are smooth steel bars, and 10 and 12 are deformed steel bars.
