Abstract
This paper analyses the bond behaviour of epoxy coated rebar induced self-compacting concrete. Experimental program is designed to check the workability and pullout tested is performed to evaluate the bonding performance of rebars. Two mixes of self-compacting concrete are chosen to form a fine paste of cement that could make bonding between concrete and reinforcement. A reference mix of SCC is made using ordinary reinforcement and pullout test values are compared. Workability and compressive strength values of SCC are also analysed and compared.
Highlights
Concrete is a complex material, which has a versatile role in construction industry
In this study epoxy coated rebars are induced in self-compacting concrete (SCC) to study the bond behaviour of reinforcement
To conduct pullout test on SCC, specimens were made with rebars at the center and rebar is arranged such that nearly 60cm is outside the cylinder
Summary
Concrete is a complex material, which has a versatile role in construction industry. Reinforcement is induced in concrete to increase the tensile strength and to withstand the loads on the structure. In recent years corrosion has been prevailing phenomenon that could weaken the strength of concrete. Major reasons of corrosion would be like exposure of concrete to the chloride environment very likely marine environments, where chloride contents very severe. Studies are carried out to test resistivity of rebar to chloride environment. Use of self-compacting concrete (SCC) is increasing due to its high workability and strength. In this study epoxy coated rebars are induced in SCC to study the bond behaviour of reinforcement
