What is Lightweight Concrete? (with pictures)

Some lightweight concrete may be used in structural applications. Structural concrete, whether an approved lightweight or a normal weight concrete, is used for applications calling for a high level of strength and compression rating. These might be highway overpasses, bridges, high-rise buildings, and construction in areas prone to earthquakes.
