How much cement powder is used in a yard of cellular concrete?
A typical basic cement/water slurry mix may have 2300 pounds of Portland powder and 1050 to 1150 pounds of water. To make it easy, lets round this to 120 pcf density. If we add foam to make a 60 pcf density cellular concrete, we will have two yards of finished material with 1150 pounds of powder per yard — more than standard density concrete. If we add enough foam to get to a 40 pcf density, we will have about three yards of finished cellular concrete with about 770 pounds of powder per yard.
