My dad used to make it.He could get the density down to 11-pounds/per cubic foot,versus about 130-pounds/cu- ft for conventional concrete.

Do you know how he did it? Detergent in the mix or forced air bubbles?
My father took a 5-panel door into a room once and stripped the paint in 1/2 hour. He never told me how he did that.
