Glass fiber-reinforced polymer (GFRP) concrete reinforcement exhibits high strength, is lightweight, can decrease time of construction, and is corrosion resistant. However, research has shown that chemical reactions deteriorate the GFRP reinforcing bars over time, resulting in a reduced tensile capacity. This paper develops a time-variant probabilistic model to predict the tensile capacity of G...

During the last four decades the biodegradable polymers have found their place in special applications in biomedical and technical fields. [1-4] However, their worldwide production volumes are still marginal compared with non-biodegradable polymers. One of the major restricting factors for the wider use of biodegradable polymers in the field of load bearing medical devices, packaging, and consu...

This paper highlights the philosophy and concepts used for of the design of prestressed concrete structures prestressed by fibre reinforced polymer (FRP) tendons and rods proposed for the Canadian Standards Association (CSA) S806-00 Standard "Design and Construction of Building Components with Fibre Reinforced Polymers". The paper deals with the section of the code which applies to concrete bea...

Carbon fiber reinforced polymer (CFRP) sheets are externally bonded to reinforced concrete (RC) members to provide additional strength such as flexural, shear, etc. It has been widely accepted that carbon fiber reinforced polymers (CFRPs) can be used effectively to strengthen reinforced concrete (RC) members. This paper is intended to study and use externally bonded CFRP strips to repair and st...

Although acrylic monomers are strong skin sensitizers (1), their corresponding fully cured polymers are considered to be inert. Until recent years, allergic contact dermatitis caused by acrylates, the term comprising, in the following, also methacrylates, was primarily an occupational disease among dentists, printers, and fiberglass workers (2). In our practice, there has been a steady increase...

This study performed an experimental investigation of asphalt concrete with and without fiberglass geogrid reinforcement, using specimens in the laboratory situ. A 100kN/m was used. The results showed that flexural strength increased by 24.82%, deformation significantly reduced, elastic modulus did not improve significantly. In addition, Hamburg Wheel Tracker test, reinforced samples had a 7.41...

The purpose of this study was to compare the structural properties of a new vs. established design of composite replicate femurs and tibias. The new design has a cortical bone analog consisting of short-glass-fiber-reinforced (SGFR) epoxy, rather than the fiberglass-fabric-reinforced (FFR) epoxy in the currently available design. The hypothesis was that this new cortical bone analog would impro...
