Reinforced concrete, a kind of precast concrete, is made by placing steel bars in formwork and pouring concrete over it. In addition, the formwork is vibrated to remove air pockets and evenly distribute the material. The most common uses of reinforced concrete include columns, beams, foundations, sidewalks, etc.

On the other hand, prestressed precast concrete is poured over tensioned steel bars to create greater tensile strength. This makes prestressed concrete ideal for large-scale applications such as commercial buildings and highway overpasses. It is less prone to cracking under load, allowing for larger spans like those found in bridges.

Precast concrete is versatile; able to be molded into various shapes, colors, textures, and sizes. Furthermore, each unit is consistent in quality because they are created in a controlled environment. Choosing between the different types of precast concrete depends on the application because each type has its unique advantages and disadvantages.
