Precast concrete is a form of concrete that is prepared, cast and cured off-site. This is usually in a controlled factory environment.
Precast concrete elements can be joined to other elements to form a complete structure. It is typically used for structural components. The components range from wall panels, beams, columns, floors, staircases to pipes and tunnels.
Here is why precast concrete is becoming a darling for builders and developers:
Precast concrete is a highly flexible product. It can be presented in several forms in terms of sizes, shapes and finishes. Precast products are used in a variety of applications, including buildings, civil construction and landscaping.
Concrete is fire resistant. Not only is it built to ensure longevity but it is also engineered in such a way that it inhibits the spread of the fire from one building to another. Precast is also strong enough to withstand impacts, blasts and natural catastrophes.
The fact that precast undergoes factory production allows for a wide choice of surface finishing, color range as well as special shapes. Moreover, the mouldability quality enables designers to copy classical details like keystones and capitals.
They can also match the finish of materials like weathered stones. The precast concrete industry can source a wide range of combinations locally and offer a tremendous variety aesthetics.
Precast concrete retains its good condition throughout its life. This, then, negates the need for chemical treatment to protect it against rot and insect attack. This makes it eco-friendly as there are no this means that there are no emissions in the internal environment.
In addition, precast is durable. This is evident in some of the initial structures by the Egyptians and Chinese which still stand to date. It serves as the go-to material in cases where longevity is required in buildings.
Moreover, the effective design detailing helps to lengthen the life of a concrete building. Similarly, precast manufacturers can offer guidance on designing for durability.
Precast is made from natural raw materials (stones, gravels, sand, cement). These materials are locally available almost everywhere and in an enormous quantity. It also boasts of a recyclable attribute.
