Effective concrete types with carbon fiber

Carbon Fiber Post-Strengthening of Concrete Structures

Introduction In the 1970s, exterior bonded steel reinforcement was used sporadically to reinforce bridges to attain higher service load capacities. This steel post-strengthening system consisted of steel straps bonded with epoxies to the exterior of concrete beams. An alternative to the steel retrofit is woven carbon fiber reinforced polymer fabric applied in the same manner as steel. Carbon fi...

Damage Detection of Carbon Fiber-reinforced Concrete Under Bending Test

Mechanical Behavior of Steel Fiber-Reinforced Concrete Beams Bonded with External Carbon Fiber Sheets

This study investigates the mechanical behavior of steel fiber-reinforced concrete (SFRC) beams internally reinforced with steel bars and externally bonded with carbon fiber-reinforced polymer (CFRP) sheets fixed by adhesive and hybrid jointing techniques. In particular, attention is paid to the load resistance and failure modes of composite beams. The steel fibers were used to avoiding the rip...

Bond Development Between Carbon Fiber Reinforced Polymers and Concrete

Carbon fiber reinforced polymer (CFRP) sheets can be externally bonded for retrofit of concrete structures, improving flexure and sheer strength in the concrete. The key to CFRP sheets is the bond to the concrete, as bond is the means to transfer stress between the tow sheet and the concrete. Experimentation has been conducted to test a current market fiber-resin system, and to develop a resin ...

Durable Glass Fiber Reinforced Concrete with Supplimentary Cementitious Materials

Durability of concrete structure in marine environments is a big issue for many decades due to chloride attack. Chloride penetrates the concrete structure and accelerates the corrosion process of reinforcement which decreases the life of those structures. Also shrinkage cracks in concrete play main role for chloride penetration through concrete surface.  Many researchers tried to find easy and ...
