An Experimental Study On The Bond Strength Between Reinforcement Bars And Concrete As A Function Of Silan And Siloxane Basedcoating And Corrosion L

摘要

Studies have been carried out to investigate the performance of silane-siloxane based hydrophobic emulsioncoating (SS)on reinforcement corrosion and bond strength. The SS is an emulsion which is silane / siloxane combination based.The coated and uncoated concrete specimens were subjected to accelerated corrosion to determine the time-to- corrosion initiation.The accelerated corrosion test results clearly showed that the specimens coated withSS performed very well against reinforcement corrosion and better than uncoated specimens.Pull out test results showed that the positive effects of SS coating on the bond strength are negligible according to uncoated specimens before accelerated corrosiontest.On the other hand, the experimental results indicated that the coated specimens exhibit higher bond strength as compared to uncoated specimens after accelerated corrosion test.
