Precast concrete is a construction method in which concrete is cast & reinforced in a multipurpose mold and then cured in controlled environmental conditions at a dedicated plant. The cast is then transported to the construction site, where it will be erected. Precast concrete may be used to create structural elements such as an intricate concrete frame, wall, or floor.
Precast reinforced concrete is ideal for creating marvels in architectural designs, but there are always pitfalls to avoid in such a project. It’s best to know where the natural strengths of precast concrete lie to maximize your savings & enhance project integrity.
Here are some precast concrete advantages & disadvantages to keep in mind over this matter!
1. Prefab Concrete Saves Time
Concrete pre-casting eliminates the time and the danger of project delay. The precast concrete casting may be done at the same time as other site works such as earthwork, survey, and so on, saving time.
2. Enhanced Quality
The quality of construction, particularly curing, temperature, mix design, formwork, and so on, may all be monitored for Precast Concrete. As a result, higher-quality work can be carried out.
3. Concrete is Pre-Stressed
Pre-stressed concrete can be used to create structural components with higher strength and load-bearing capacity, resulting in greater clear span, the decreased cross-section area of structural members, and so on.
4. Increased Savings in Materials
Using prefabricated components makes it possible to build a structure in much less time and for less money than traditional methods. The construction process is simplified increasing productivity, quality, and safety. As a result, the cost is reduced.
5. Durable & Resilient
Precast concrete is more expensive to build than masonry but lasts longer. It may also take longer to construct but requires minimal maintenance if installed right. The high-density property of precast concrete is more resistant to acid corrosion, impact, surface voids, and dust accumulation than standard concrete.
1. High Initial Costs
Heavy and sophisticated equipment is required for installing a Precast Concrete plant, which necessitates a substantial initial investment. To ensure adequate profit, a broad range of precast construction projects must be accessible. Transportation of the concrete can also be time-consuming over long distances & rugged terrains, which further adds to the cost.
2. Handling Expertise Required
Precast concrete has to be handled with care and caution. The cast & reinforced parts are typically hefty and big, making them difficult to handle without causing harm. Portable or tower cranes are usually employed to pick up precast elements, which calls for capable operators.
3. Limited Modification Options
It’s difficult to make changes to precast buildings since they are constructed to completion and cannot be dismantled. If a structural wall is removed for modification, it impacts the overall stability of the structure.
4. Tricky Joint Connections
Connections between individual precast parts must be carefully maintained to guarantee desired movement and behavior of the joint link, such as simple, semi-rigid, or firm connections. Water penetration through faulty connections can lead to water loss and sound insulation failure.
