What are the different shapes of reinforcements used for concreting?

Reinforcements, also known as rebar, are used in concrete construction to provide additional strength and support to the structure. The most common shapes of reinforcements used in concrete construction include:

  1. Round: Round reinforcements are the most common type of rebar used in construction. They are easy to bend and cut, and can be used in a variety of applications.
  2. Deformed: Deformed reinforcements have a rough surface, which helps to improve the bond between the concrete and the reinforcement. They are commonly used in construction to provide additional strength and support to the structure.
  3. Square: Square reinforcements are less common than round or deformed reinforcements, but they are still used in some applications. They are typically used in cases where a larger surface area is needed for bonding with the concrete.
  4. Rectangular: Rectangular reinforcements are similar to square reinforcements in that they provide a larger surface area for bonding with the concrete. They are commonly used in cases where a larger surface area is needed for bonding.
  5. Truss: Truss shaped reinforcement are used to provide additional strength and support to the structure especially in case of shear force. They have a zigzag shape which increases the bond strength.

In summary, there are several different shapes of reinforcements used in concrete construction, including round, deformed, square, and rectangular and truss. The choice of shape will depend on the specific requirements of the structure and the loads it will be subjected to.

What are the different types of reinforcements provided in concrete?

Reinforcement in concrete is used to provide additional strength and support to the structure. The most common types of reinforcement used in concrete are steel bars (rebar), welded wire mesh, and fiber reinforcement.

Steel rebar: Source

Steel rebar is the most common type of reinforcement used in concrete construction. It is made of carbon steel and is available in various sizes and grades. It is used to provide tensile strength to the concrete structure and can be used in both horizontal and vertical applications.

Welded Wire Mesh: Source
  • Welded wire mesh is made of steel wire and is used to provide additional strength and support to the concrete structure. It is typically used in slabs, walls, and beams.
Types of Fiber reinforcements: Source
  • Fiber reinforcement is made of synthetic or natural fibers and is used to provide additional strength and support to the concrete structure. It is typically used in thin or lightweight concrete structures, such as walls or slabs.
  • Glass fiber reinforced concrete (GFRC) is a type of fiber reinforcement that uses glass fibers to provide additional strength and support to the concrete structure.
  • Carbon fiber reinforced polymers (CFRP) is another type of reinforcement made of carbon fibers, it is used to provide additional strength and support to the concrete structure, it is typically used in structures that requires high strength and low weight.

All these reinforcements have their advantages and disadvantages, and the choice of reinforcement will depend on the specific requirements of the project and the structural design.
