Torsional Strength of Reinforced Concrete Beams with Brine and Olive Oil Mill Wastewater

The authors conducted a comprehensive research study on adding olive oil mill and brine wastewater to the concrete mix investigate torsion, bending stress, shear, compressive strength. total number of specimens were 33 beams 100 mm (depth) × (width) 500 (length). Three used as control samples, thirty divided into two groups: fifteen samples from an mill, other with different percentages additive material (olive wastewater), 2.5, 5.0, 7.5, 10.0, 15.0 % each. reinforced 4 ϕ 8 longitudinal steel bars stirrups spaced at 20 mm. All tested 28 days. It was found that torsional strength containing when added best percentage, which is 10%, 5.46 MPa. As case 7.5%, it 5.16 These data are greater than in reference 4.38 MPa, meaning increases by 24% 17%, respectively. Doi: 10.28991/CEJ-2023-09-03-012 Full Text: PDF
