ADVANTAGES OF PRECAST CONCRETE
Saves Construction Time:
Precast Concrete construction saves time, and the risk of project delay is also less. The precast concrete casting can be carried on simultaneously with other works on site such as earthwork, survey, etc., and thus saves time. It is a major advantage of precast concrete.
Quality Assurance:
The key factors which regulate the quality of construction such as curing, temperature, mix design, formwork, etc. can be monitored for pre cast concrete. So, improved quality construction can be performed.
Usage of Prestressed Concrete:
By using pre-stressed precast, structural materials of high strength and load-bearing capacity can be achieved, which can result in greater clear span, reduced size of the cross-section of structural members, etc.
Cost-effective:
The simplified construction process reduces time, increases productivity, quality and safety and thus the cost is reduced.
Durability:
Precast Concrete structure has a longer service time period and minimal maintenance. The high-density Precast Concrete is more durable against acid attack, corrosion, and impact, reduces surface voids, and resists the accumulation of dust.
Aesthetics:
As the structures are made of prefabricated concrete in a controlled factory environment, several combinations of colors and textures can be used. A wide range of shapes and sizes are available to choose from with smooth finishing and thus the aesthetical value of products is increased.
Safe Construction Platform:
No raw materials have to be stocked on the site for precast concrete construction. It reduces the requirement of traditional formworks and props, wastage, workers, etc., and thus provides a safe working platform.
Less time needed to install
Precast concrete components are ready for immediate use upon delivery while cast-in-place concrete are not. This eliminates unnecessary time needed to set up cardboard forms, bend and position rebar, pour and vibrate concrete and then wait for the concrete to cure. The removal of these steps saves valuable time in terms of project duration and cost from labor needed.
Construction speed
Prefabricated construction is also associated with faster build times; while traditional construction takes typically 6-16 months to finish, prefab can be completed in 6-8 weeks or less.
Seasonality
While traditional construction projects that are limited to prime seasons, and plagued by external factors, prefabricated constructions produce the majority of their built components indoors and offer higher quality builds.
