Experimental Study of Bond Stress between Concrete and FRP Rebars

Abstract

Owing to the excellent tensile strength and corrosion-resistance of fiber reinforced unsaturated polyester composite, it is expected to solve the corrosion problem of building instead of steel bars in some special occasions. Bonding performance between concrete and FRP rebars was studied by pull-out test,the influences of the surface form, anchorage length and diameter of FRP rebar on bonding strength were discussed in detail.

Bond-behavior study of newly developed bamboo-composite reinforcement in concrete

“…As it was mentioned earlier, the difference between coarse and fine sand particles in developing bond strength is not statistically significant since both particle sizes improve the bonding through friction similarly as shown in Table 3. The bond strengths of bamboo-composite bars with and without coating were similar to the bond strength of plain glass fibre reinforcement in normal strength concrete [29][30][31]. However the bond strength is only 80% of the bond strength of plain steel reinforcement in normal grade concrete with similar embedment length used in this study [32,33].…”

A Review on the Physical Parameters Affecting the Bond Behavior of FRP Bars Embedded in Concrete

“…There has been a great deal of research undertaken in the literature on the effects of embedment or development length on the FRP-concrete bond strength [22,24,38,47,70,[75][76][77][78]. Two modes of behavior were reported in these studies.…”
