Why is prestressed concrete commonly used in modern construction?

Prestressed concrete is commonly utilized in modern construction primarily due to its unique strength that effectively counters service loads. This construction method involves the intentional application of pressure to the concrete, which significantly enhances its ability to withstand tensile stresses. As a result, prestressed concrete can support larger spans and carry greater loads compared to traditional reinforced concrete.

Additionally, this increased strength allows for reduced structural volume and material use, which can lead to cost savings and efficient designs. Projects that involve long bridges, high-rise buildings, and heavy industrial floors take advantage of these properties to meet safety and performance standards.

While the other options may have their own merits, they do not explain the primary reason for the widespread use of prestressed concrete in construction. For instance, the notion of being easier to form or being lighter than traditional concrete does not directly relate to the fundamental benefits that prestressed concrete offers in terms of load-bearing capacity and structural integrity.
