Concrete is a material used in the construction of a high rise building, coastal, offshore sea structures and other industrial structures for a long time. The recent technological advances have extended its use to special applications like aircraft engine test cells, nuclear reactor vessels, nuclear bunker busters, nuclear stock pits, missile launching pads etc. It is now possible to look at relative methodology that is required in concrete for various applications and where an admixture is typically used to achieve the requirements. In order to aid in this adaptation process various chemical...

The shear performance of RC beams is an important aspect to consider in the design of strengthening systems. Shear failure can occur in RC beams when the applied load exceeds the shear capacity of the beam. This failure mode can be dangerous and can lead to structural collapse.Various configurations of FRP systems have been used to strengthen RC beams against shear failure. Some of these configurations include, FRP sheets bonded to the web of the beam, FRP sheets bonded to the soffit of the beam, FRP plates bonded to the web of the beam and Near-surface mounted (NSM) FRP rods or strips. In...
