1.5 cubic yards of cement are needed for an 11' x 11' x 4" slab.

for ,this we need to calculate the volume of concrete . volume of concrete = L x B Xh. =17 X 4 X24 . =1632 inch cube. Thus,1632 cubic inches concrete is needed for 17 inch by 24 inch by 4 inch deep .

Poured concrete has an R value of about 0.08/inch. Fiberglass batt has an R value of about 3.14/inch (blown fiberglass wall insulation is about 3.2/inch). From these values we can calculate that the equivalent insulating thickness of concrete would be about 3.5x3.14/0.08 = 137.4 inches. Note that concrete blocks have a somewhat better insulating value due to the incorporated air pockets. A 4" concrete block has an R value of about 0.2/inch An 8" concrete block has an R value of about 0.15/inch A 12" concrete block has an R value of about 0.1/inch

Where are 12 inch concrete blocks applied?
