Effect of Corrosion on Bond between Steel and Concrete of Corroded and Inhibitive Reinforcement Embedded In Reinforced Concrete Structures in Accelerated Corrosive Medium
Journal Title: IOSR Journal of Mechanical and Civil Engineering (IOSR-JMCE) - Year 2018, Vol 15, Issue 2
Abstract
This Study Evaluated The Experimental Effect Of Corrosion On Bond Existing Between Steel And Concrete Interface Of Corroded And Resins / Exudates Coated Reinforcement With Ficus Glumosa Extracts From Trees. Resins / Exudates Paste Were Directly Layered On Reinforcing Steel Of Varying Thicknesses Of Thicknesses 150µm, 250µm And 350µm, Embedded Into Standard Cube Size Of 150 Mm X 150 Mm X150 Mm. Uncoated And Coated Concrete Cube Members Of 18 Samples Were Immersed In Saline Marine Environment Of Sodium Chloride (Nacl), Accelerated For 60days For Corrosion Potential Possibility Observation. Results Obtained Indicated Corrosion Potential Presence On Uncoated Concrete Cube Members. Experimental Samples Were Subjected To Tensile And Pullout Bond Strength And Obtained Results Indicated Failure Load, Bond Strength And Maximum Slip Values Of Coated Were Higher By 33.50%, 62.40%, 84.20%, Non- Corroded By 27.08%, 55.90% And 47.14% Respectively. For Corroded Cube Concrete Members, The Values Were Lower By 21.30%, 38.80% And 32.00% On Failure Load, Bond Strength And Maximum Slip To Those Ones Obtained By Non-Corroded And Coated Members. The Entire Results Showed Good Bonding Characteristic And Effectiveness In The Use Of Ficus Glumosa Resins / Exudates As Protective Materials Against Corrosion.
