Concrete is used for construction at large. Its usage stands as the second most used construction material standing only second to water. The material comes with some substantial benefits as well as uses. But in addition to that, concrete is used as precast forms through die casting. This is called precast concrete.
This type of concrete proves even more beneficial than traditional concrete pouring. Yet making this is even harder than the usually used concrete mixture.
How is Precast Concrete Made?
As concrete is made from its constituting elements, precast too is made. But this is a rather long process. This process requires precision at every step to make sure that the precast is right for the project. Just as the name suggests it is pre-casted into different forms.
The process goes as:
But before even making these forms, the project’s 3d detailed drawings are made. Precast detailing services can be availed by contractors, fabricators, or project owners. These drawings include every detail for the aggregate construction of the project. To ensure accuracy computer software is used. As the drawings are approved the next step can begin.
Next, the rebar cage is made. The correct rebar is picked and prepared for the exact requirement. This covers the cutting and bending of the bars. This bend and cut bars are bound together into the required cages.
After making the cage, the form is prepared. Opening, cutouts, and embedded items are included in this step. Also, form release is applied to the form’s surfaces so that the precast can be easily lifted. Then the cage is placed in the form. Then quality assurance is marked by the expert.
Cement, coarse aggerates, sand, and admixtures are mixed in a specific quantity. The quality of each constituent is ensured through tests. The mixture is added to the form while ensuring that it traps no air voids. Later the top of the form is screed off and finishing is applied.
The product of the form is tarped the product overnight. The environment allows it to absorb heat and reach the proper design strength. Then the QC technician certifies that the precast has reached the required strength. The product is removed from the form.
Now the product is cleaned and inspected. This post-poured inspection includes ensuring design dimension and visual defects. Once this is done, the QC technician’s work is done. Lastly, the product is labeled and transported.
Then the product is stored on dunnage to ensure that it stays fit for customer demand. As the customer makes his order, the product is transported to his location with proper care.
Its Usage at the Construction Site
Once the precast concrete is delivered to the customer, which is either the contractor or fabricator, it is utilized. This process is much easier as compared to building walls, roofs, floors, or other architectural components through brick or other materials. As per the simple concrete pouring, every brick is laid and concrete is poured over or applied to build a wall. While through precast concrete the process is much eased.
Once the precast concrete past product is transported to the construction site, at first it is stored. This storage should be enough to prevent any damage to it. This could be physical damage such as crakes, spills, or chipping.
The products are lifted by a crane and placed over the location planned for the project. Place all the products concerning a project in the exact location. This needs to be precise. One controlling the crane must pick and drop the product in the right place carefully.
Conclusion
Precast is a highly beneficial construction way. This can help the products in various means. Hence to make it right various details are ensured. Drafting services can be of excellent assistance in this. Only then is the required product made in the form of precast and project.
