This study evaluated the naturally extruded exudates/resin from plants of inorganic origin with eco-friendly and environmentally non-hazardous materials derived from tree trunks. Exudates/viscous adhesive is then embedded into the concrete beam after layers of different thickness and applied directly to the steel reinforcement. This study further aimed to determine the role of exudates/resins in harmful attacks on reinforcement by water tightness and durability (resistance) and modifications of steel reinforcement surface due to coating. In comparison, the results of the flexural strength exhibited at the maximum for the controlled sample is 27.86% compared to the corroded with -20.75% and coated sample of 27.87%, respectively. Differential mean values and percentile ranges were checked to be (0.55kN and 1.43%) for the controlled, (0.66kN and 1.04%) corroded and (0.52kN and 1.69%) coated. Corroded specimens fail with a lower load applications and high yielding, whereas coated specimens have a higher load to failure and lower yield occurrence. The results further confirmed that the flexural failure loads of the controlled and coated specimens maintain a narrow range of values over the corroded specimens at moderate, reduced and lower loads. The comparative results showed that the maximum value of the controlled state is -38.58% compared to 63.61% corroded and controlled -37.96%. The recorded mean and percentage difference values were examined and computed to be (0.26kN and 0.93%), corroded (0.26kN and 2.42%) and coated (0.27kN and 0.92%). The results showed a lower failure deflection load in the controlled and coated samples with a reduced value over the corroded sample with a higher failure deflection load and an increasing value compared to the reference range (controlled) and the layered (coated) sample. The comparative obtained results during and after the corrosion test for the maximum value of the rebar diameter is 0.53% compared to the corroded -0.74% and the coated sample 0.85%. The computed mean differential and percentile values were (0.02% and 0.03%), the corroded values were (0.03kN and 0.11%) and the coated values were (0.01kN and 0.11%). The results showed the effect of corrosion on the mechanical properties of reinforcing steel with a smaller diameter, where the average value and the percentage of corroded samples decreased, while the controlled and coated samples showed a preserved condition, with an increase in the diameter of the coating emanating from the varying coating thicknesses from the exuates /resin. The cross-sectional area of the reinforcing steel mean and percentile values calculated from the corroded values are (0.02 and 6.19%) and the coated values (0.02 mm and 5.21%). The results obtained showed the effect of corrosion on the mechanical properties of reinforcing steel with a decrease in the diameter of the reinforcement in the corroded sample, while the coated sample showed an increase in the thickness of the exudate paste layer. The differential calculated average and percentage yield strength and ultimate tensile strength (6.93MPa and 5.46%) and (2.53MPa and 0.02%), the corrosion value was (2.81 MPa and 5.01%) and (2.53 MPa and 0.02%). the values covered are (3.98MPa and 5.46%) and (2.56MPa and 0.01%). From the data obtained and compared, the yield strength and tensile strength values of the corroded sample take into account the mean and percentile values reduced with load damage with low application. The comparative strainn ratio obtained from the calculated maximum values for the mean and percentile values for the control was -3.19% compared to the corroded and overlaid values of 3.29% and -2.88%, respectively. The mean differential and percentile values obtained for the control were (0.42 and 0.3%), corroded values (0.42 and 0.32%) and closed values (0.43 and 0.31%). The results showed that the corroded sample had a higher percentage of deformation due to lower breaking load and higher yield strength, while the coating had a higher breaking load with lower yield strength. The calculated data for the maximum percentage of reinforcement weight before corrosion test for controlled, corroded and coated values were 0.05%, 0.05% and 0.07%. The maximum comparison values recorded after the corrosion test for the controlled sample remained the same, with no trace of a corrosive effect, as it was collected in fresh water, for the corroded and coated samples the values obtained were -6.82% and 7.76%, respectively.
