Concrete strengthening techniques like jacketing, steel bonding, and carbon fiber reinforcement are used to improve the structural integrity and load-bearing capacity of existing concrete structures. Each method has its unique characteristics and advantages:

1. Jacketing
Jacketing, also known as concrete jacketing or concrete encasement, is a method of strengthening existing concrete elements by adding a new layer of concrete around them. This new layer, typically referred to as a "jacket," is designed to enhance the strength and durability of the original concrete structure.

The process involves preparing the surface of the existing concrete by cleaning and roughening it to ensure good adhesion. Then, a new layer of concrete is applied over the surface, often with the use of reinforcing steel bars (rebar) or mesh for added strength. The new concrete jacket bonds with the original structure, creating a composite system.














2. Steel Bonding
 
Steel bonding, or externally bonded steel reinforcement, is a method of reinforcing and strengthening existing concrete elements by affixing steel plates or bars to the external surface of the concrete. This method is used to enhance the structural performance and load-carrying capacity of concrete members.

Steel plates or bars, typically made of materials like carbon steel or stainless steel, are bonded to the concrete surface using epoxy adhesive. The steel elements provide additional tensile strength and help distribute loads more effectively throughout the concrete structure.











3. Carbon Fiber Reinforcement
Carbon fiber reinforcement, often referred to as carbon fiber wrapping or carbon fiber reinforcement sheets, is a technique for strengthening concrete structures using carbon fiber-reinforced polymer (CFRP) materials. CFRP is a composite material consisting of carbon fibers embedded in a polymer resin matrix.

In this method, carbon fiber sheets or strips are bonded to the concrete surface using a suitable adhesive, typically epoxy. Carbon fiber has an exceptionally high strength-to-weight ratio and is applied in the form of sheets or strips. It is a versatile method for reinforcing and increasing the tensile strength of concrete structures. It is often used for its lightweight, high-strength properties and ease of application.












These methods are employed based on the specific requirements and conditions of a project. Jacketing is suitable for enhancing the overall strength of a concrete element, steel bonding is effective for increasing load-carrying capacity and ductility, and carbon fiber reinforcement is known for its high-strength and non-corrosive properties, making it suitable for various applications, including seismic retrofitting and repairing deteriorated structures.
