What is precast concrete advantages and disadvantages?

The concrete of superior quality is produced as it is possible to have better technical control on the production of concrete in factory. It is not necessary to provide joints in the precast construction. The labour required in the manufacturing process of the precast units can easily be trained.

What are the disadvantage of precast concrete?

Disadvantages of Precast Concrete

• High Initial Investment: For installing a Precast Concrete plant, heavy and sophisticated machines are necessary which requires a high initial investment.
• Transportation Issue: The construction site can be at a distant location from the Precast Concrete plant.

What are the advantages and challenges in precast structures?

The precast construction technology offers advantages such as 1) cost-saving, 2) Time savings, 3) Quality enhancement 4) Less labor required, 5) Enhanced safety 6) Reduced wastage.

What are the advantages of precast concrete construction over cast in situ?

Precast concrete construction is quick as it can be installed immediately and there is no waiting for it to gain strength. Increase in strength can be achieved by accelerated curing. On site strength test is not required. High strength concrete can be used because it is in controlled condition.

Why is precast concrete durable?

The choice of precast concrete in a building or structure means that resilience is built in. The inherent properties of the material help it to withstand all manner of weather conditions, infestations and other less common threats such as explosions.

Is precast concrete better for the environment?

Precast elements have many natural advantages over pouring concrete at a job site. The environmental conditions in a precast concrete facility are much more consistent and can be managed much better than at a construction site, resulting in better quality.
