Which type of concrete is specifically designed to hold weight?

Structural concrete is specifically formulated to resist compressive forces and hold significant weight, making it essential for construction applications that require load-bearing capabilities. This type of concrete typically contains a higher proportion of cement and aggregates, which are designed to create a strong and durable material capable of supporting heavy loads, such as those encountered in floors, foundations, and beams.

In contrast, insulating concrete is designed primarily for thermal insulation, lightweight concrete is formulated to reduce overall weight while still maintaining some structural integrity, and decorative concrete focuses on aesthetic appeal rather than structural strength. Each of these other types serves specific purposes but does not possess the load-bearing characteristics that define structural concrete.
