Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems.
There are two principal reasons for its use.
The water retained by the air entrained concrete and the more porous lightweight aggregates also greatly increases the cure time for fully dry material.
If you re putting in new concrete floors on grade the weight won t be a concern.
