Question:

In civil engineering, which statement regarding lightweight concrete is incorrect?

A$)$ Lightweight aggregates used in lightweight concrete include materials such as expanded clay, shale, and pumice, which contribute to its reduced density.

B$)$ The reduced density of lightweight concrete results in lower structural strength compared to conventional concrete, making it unsuitable for load$-$bearing applications.

C$)$ Lightweight concrete is commonly employed in construction projects where minimizing dead load is essential, such as in high$-$rise buildings and bridges.

D$)$ Incorporating lightweight aggregates into the concrete mixture enhances its workability and reduces the overall construction cost by requiring less material for a given volume
