Art-of-review on CFRP Wrapping to Strengthen Compressive and Flexural Behavior of Concrete

Abstract

Strengthening of reinforced concrete structures is given top priority in construction sector across the world. Ageing and load pattern changes will affect the stability of structure may be reduced. In this case, Fibre-Reinforced Polymer (FRP) materials are recognized as vital constituents to solve stability issues of the modern concrete structures. The purpose of present constructive studies of various techniques for FRP retrofit concrete structures because, the FRP material has improves the structural performance in terms of stability, stiffness, strength and durability such that the Fibre-Reinforced Polymers wrapping is one of the techniques to regain the strength of a concrete structures. By various researchers the different wrappings techniques are used to regain the strength and also enhanced the durability of the structure. This paper focuses mainly on various wrapping techniques of FRP sheets for external strengthening of RC structures such as reinforced circular columns, square beams, columns and column-beam joints.

Alkali-Activated Slag cement: Alternative Adhesives for CFRP Sheets Bonded to Concrete at Elevated Temperatures

“…Hence, the fireproof adhesives with no cement or reducing the cement content have become research hot spot recently. In this study, blast furnace slag was adopted as an alternative of cement to produce AASC, and the purpose is to develop a high-temperature-resistant inorganic matrix for RC enhanced by FRP [19][20][21][22].…”
