First, we have to understand what is precast concrete. Precast concrete can also be called readymade concrete or prefabricated concrete. Following is the definition of precast concrete. The form of construction where concrete is cast in a reusable mold and then cured in a controlled environment (a precast plant) is called precast concrete. The casted structural member is then transported to the construction site and then erected. Structural members such as concrete frames, concrete walls, concrete floors, etc. can be constructed using precast concrete. There are many precast concrete advantages. They are discussed below.1. 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. 2. 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. 3. 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 4. Cost-effective: The simplified construction process reduces time and increases productivity, quality, and safety and thus the cost is reduced. 5. 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.)
