Pre-cast Concrete Walls

Precast concrete walls are constructed by casting concrete in a reusable wall mould or form which is then cured in a controlled environment, transported to the construction site and lifted into place. The main function of the precast walls is to speed up the construction process.

Types of Precast Concrete Wall

1. Cladding or Curtain Walls

The cladding or curtain walls are the most widely used precast wall for building envelopes. They are non-load bearing walls intended for the use to oppose the wind and encase the space. This type of precast wall incorporates divider boards, window divider units, spandrels, mullions, and section covers.

2. Load-bearing Wall

Load-bearing wall units oppose and exchange loads from different components and cannot be removed or dismantled without influencing the quality or dependability of the building.

3. Shear Walls

Shear walls are utilized to give a parallel load opposing framework when joined with stomach activity of the floor development. The viability of precast shear dividers is generally needy upon the board-to-board associations.

Characteristics of Precast Concrete Walls

1. Thermal Resistance

The precast walls infer their warm execution attributes basically from the measure of protection set in the depression or inside the reinforcement divider, which is ordinarily a metal stud divider.

2. Moisture Protection

The protection for the moisture in the precast walls is of high importance as the structural members such as columns and beams are not structurally connected with the precast walls.

The sealer or the joint seal used in the connections and joints to prevent the moisture from entering the building. To keep the uniformity of precast walls and the sealants, pigmented sealants are used.

3. Fire Safety

The precast walls are manufactured with concrete which has good fire-resistant material.

4. Acoustics

A precast wall with a veneer will give comparative execution with respect to sound transmission from the outside to the inside of the building.

5. Durability

The durability parameter of the precast walls is the same as that of concrete. Anyhow, the durability depends on the type of connections made with the structural member.

Any irregularities in the member can be rectified by sandblasting, uncovering total, corrosive washing, hedge pounding, or different methods.

6. Maintainability

As the walls are manufactured with concrete, which does not need any maintenance. The connection, sealants, anchorages, and accessories used in the precast walls need regular maintenance.
