Guide for the Design and Construction of Concrete Reinforced with FRP Bars (ACI 440.1R-03)
This paper reports on the key features of the “Guide for the Design and Construction of Concrete Reinforced with FRP Bars” issued by the American Concrete Institute (ACI). For new construction, FRP bars have been used as the internal reinforcement in concrete members to replace conventional steel rebars for a host of reasons. The principles for design and construction were first established and...
متن کامل09207 - Corrosion of Epoxy- and Polymer/zinc- Coated Rebar in Simulated Concrete Pore Solution
This work is a preliminary examination of mechanistic issues on the comparative corrosion performance of regular epoxy-coated rebar (ECR) and dual polymer-zinc coated reinforcement (DCR) in simulated concrete pore solution with and without chloride ions, at polarizations from +100 mV to -1000 mV in the saturated calomel electrode (SCE) scale and exposure periods of 1 month or longer. Both mater...
متن کامل08311 - Corrosion of Epoxy Coated Rebar in Cracked Marine Substructure Concrete
Epoxy coated reinforcement (ECR) has been used in Florida from the 1970s to 1990s but has been discontinued due to the observation of severe corrosion in some ECR bridges after short service times. Corrosion projections have been made in earlier investigations based on corrosion initiation and propagation concepts but did not consider the presence of structural cracks. The current research in p...
متن کاملCorrosion of Reinforcing Bars in Concrete
The causes and mechanisms of corrosion of reinforcing bars in concrete are described in terms of the practical issues as well as the electrochemistry. The parameters affecting corrosion are (i) the ingress of aggressive species, such as chlorides, which break down the protective film on the reinforcing bar and (ii) the amount of those species necessary to do so. The former is largely controlled...
متن کاملDesigning Machine Tool Structures With Epoxy Concrete
Ab stract: The materials used in the manufacture of machine tools structures affects the metal removal rate; accuracy and surface finish of the products. The materials, in turn, have influence over the method of production, lead times and overall costs of the machine tool structures. Over a period of time machine tool builders relied on conventional materials, for the fabrication of machine too...
