Design with Lightweight Concrete. Despite the moisture issues, lightweight concrete provides a number of benefits. Lightweight concrete composite slabs are inherently more efficient than normal-weight composite slabs with nearly identical structural characteristics and design strengths.
Lightweight Concrete weighs up to one-third less than traditional concrete and is the perfect solution for a deck design that not only looks great but is also waterproof. Lightweight concrete reduces the dead load of concrete structures, allowing us to reduce the size of columns, footings and other load-bearing elements.
Just as lightweight composite materials used in aircraft manufacturing today have become the materials of choice, lightweight concrete often outperforms the normal weight concrete. Lightweight concrete's strength to weight ratio often exceeds that of normal weight concrete.
Assessment of composite steel deck floors with mesh reinforcement. Lightweight concrete is a better insulator and thus loses strength less rapidly in fire than normal weight concrete. Hence lightweight concrete floors tend to be thinner than normal weight alternatives.
