Rebar is a structural member that is cast into concrete and masonry to provide strength and reinforcement. A reinforcing bar, rebar is used to compensate for the relatively weak tensile strength of ...

The Fiber Reinforced Polymer (FRP) rebar industry is about thirty years old. The industry started by molding aramid and carbon fibers with various thermoset resins, and then expanded to glass fibers ...

Concrete has long been used as a building material for its high compressive strength, good durability and low cost. However, its well-known Achilles’ heel is its brittleness and limited tensile ...

While many of us might think that concrete structures such as bridges simply stand unaided for decades at a time, the fact is that they require maintenance as often as once every five years. An ...

Researchers at the USA's Rensselaer Polytechnic Institute have invented an alternative to steel rebar made from hemp, which they claim avoids the problem of corrosion while cutting carbon emissions ...

In seismic zones, construction of concrete high-rises keeps getting easier, thanks to advances in high-strength reinforcing steel used for confinement of high-strength concrete. The first use of ...
