Pre cast concrete construction – What is it and why is it better?

Concrete structures are strong and durable. Construction work uses concrete to build the skeletons of buildings. They form the weight bearing structure in buildings. They are also extensively used for areas that have heavy vehicular movements and footfalls.

What is concrete?
Concrete is needed for all construction work. it is formed by mixing cement, sand, stone chips and water in appropriate proportions and pouring the mixture into prepared iron mesh molds. This mixture is allowed to set and cured for the concrete to form. The formed concrete is used in building.

What is precast concrete?
Precast concrete uses the same concept to prepare concrete offsite. The precast units are manufactured in factories. The molds have pre-stressed wires set in them and the curing is done under controlled conditions. The process is safer and faster.  The molds are reused several times. This brings down the cost of making concrete units.

Why is it an improvement on traditional concrete?

  • Precast concrete uses molds multiple times thereby affording uniformity to each unit. The handmade molds in traditional concrete can vary in dimensions.
  • Curing is done under controlled conditions giving precast concrete smoother finish. Curing done on site takes more time and is not uniform across structures.
  • The amount of mixture used for each unit is the same. In traditional concrete the amount of mixture could be different making the concrete less uniform.

Ways in which pre cast concrete is used

  • Building and expanding parking areas
  • Office buildings with unusual facades that is both functional and aesthetic.
  • Hotels, dormitories, and apartment complexes
  • Schools and hospitals

Benefits of using precast concrete

  • Precast concrete provides engineers with greater opportunity for creative designing.
  • The customized units are easily assembled and installed.
  • Saving time on curing and installing concrete translates into less expense for builders.
  • Precast concrete is fire and heat resistant.
  • Precast concrete gives you control over project time frames along with control on quality of product used
  • It can be used as structural frames and for creating facades for buildings.
  • It is easy to install.
  • Its density and strength make them ideal for sound proofing.
  • It can be tested for quality before it is installed.
  • It provides a healthier interior as it needs no chemical treatment throughout life.
  • It is made from natural and local resources. This makes it environment friendly.

Increasing use of precast concrete makes infrastructural development sustainable. it serves varied human needs at affordable pricing and simultaneously protects the environment from harm. In this way it serves the three P’s of sustainable growth.

Precast concrete construction can be used for structural parts of buildings such as beams and pillars, roofing and flooring. This concrete is equally useful in building roads and bridges. The slabs are lighter than slabs of traditional concrete. This makes them easier to handle. Use precast concrete for all your construction work and complete your projects efficiently and on time.


Why should you use precast concrete for construction?

Rapid urban development requires the help of new technology to go beyond more the traditional building methods. Precast infrastructure is one such technology that provides the means to bring up structures easily, quickly, and conveniently.

Precast technology provides the solution to infrastructural demands. It prefabricates units used in infrastructure development in controlled factory areas situated off-site. Once transported to the construction sites, these units are easy to assemble and fit to complete a structure. Reusable moulds are used to cast concrete off-site.  The concrete is cured and made ready for transportation to sites. What are the advantages of using this prefabricated concrete? Look at some of the benefits of using this material for infrastructural needs.

Less cumbersome
Precast concrete does away with the need to move cumbersome machines and all other raw material needed for making concrete to the site. It reduces the work of mixing, and carrying the mixture manually to be poured into casts prepared manually. Factory made units of concrete are a convenient construction alternative.

Precast concrete is used in all types of construction work- for building houses, commercial buildings, infrastructure development projects, and special projects. The units come in both standard shapes and sizes and can also be custom made and designed for a particular structural needs. The range of precast concrete units extends from wall sections, to concrete beams and panels to hollow blocks.

Concrete units are superior in quality. They are uniform in size, each has the same density and dimension. The standardized product ensures a better finish for the building.

Concrete produces a tough surface that withstands corrosion for long periods of time. Precast concrete has the added advantage of tighter tolerance levels. The concrete mix made in the factory uses optimum water and is adequately compacted. Problems of curing are avoided with the use of precast concrete. The units are given correct drying time and the process of drying is carried out in a controlled environment to give them maximum strength.

Benefit to the environment
Use of these concrete units benefits the environment by reducing pollution of concrete dust. Natural materials are used to manufacture this concrete to help in controlling environmental damage. The process of production absorbs atmospheric carbon dioxide and cleans the air. During demolition of structures, these units cause less pollution and toxicity in the area. The units are reusable which further helps in environmental conservation.

Variety of finish
The end user gets to choose from a range of finishes according to requirement. There are non skid surfaces, patterned surfaces, and smooth surfaces available. All the surfaces can easily be treated chemically and polished for better appearance.

Using precast concrete for construction work is a smart decision. It is safe, profitable, and durable. Precast infrastructure has rapidly grown in popularity because of its versatility and high quality. Using the blocks and units simplifies the task of constructing buildings.
