Abstract

Variation of bond stress with different anti corrosive reagent was determined. When bar is embedded in concrete it is corroded in course of time and corrosion products form pit or holes on the surface of reinforcing bar and reduce cross sectional area of steel and also reduce bond capacity. To protect corrosion, different anti corrosive reagent are available in the market. But the effect of bond, of reinforcing bar with surrounding concrete depending on product type is not known to users. A study are therefore felt important in this study. It is seen that if anti corrosive reagent is used to protect corrosion as the companies claim reduces bond stress from 13-37% depending on type of material (Brick aggregate or stone aggregate) and ratio (1:2:4 and 1:1.5:3). Development length of rebar for situation when anti corrosive reagent is used should be increase.
