Item Performance evaluation of rebar in accelerated corrosion by gravimetric loss method(2012) Shetty, A.; Venkataramana, K.; Gogoi, I.Corrosion of concrete occurs due to chloride ingress into concrete and is a major cause of steel corrosion. Rebar corrosion in concrete is one of the major problems in the durability criteria. This paper explains, experimental investigations carried out on smaller specimens for evaluating the performance of two types of cement with three types of rebar by gravimetric method. From the results of gravimetric loss obtained by different types of steel with different types of concrete, it is concluded that blended cement, i.e. PPC performs better compared to OPC against accelerated rebar corrosion in concrete. Amongst steel types, CTD steel resulted in higher gravimetric loss compared to MS followed by TMT steel. © 2012 Cafet-Innova Technical Society.

Corrosion of rebars in concrete is one of the major problems in the durability criteria. Local bond stress slip relationship is generally adopted to determine the mechanical properties of the interface between re-bars and concrete. Therefore the attainment of satisfactory performance in bond is an important, aspect of the design and the detailing of reinforcement in structural components. In this paper an overview of factors affecting specimen geometry of bond strength and Types of bond tests were studied. © 2013 CAFET-INNOVA TECHNICAL SOCIETY. All rights reserved.
