A structural light-weight concrete mix has a density of about 105 pounds per cubic foot compared to normal concrete with a density of 150 pounds per cubic foot. The light-weight concrete density is less because lightweight coarse aggregates and sometimes lightweight fine aggregates are used, which make the concrete weigh less.
