A 6-inch concrete slab can typically support around 150 pounds per square foot.
The ones that I see are 2-3/8" thick and 6"x12" in size.
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
At least 28.5 cubic yards for a 6-inch depth.
For a 4-inch depth: 4.75 cubic yards. For a 6-inch depth: 7.1 cubic yards.
You can't express a volume of concrete in yards.
Approx 10.3 US gallons.
At least 3 cubic yards for a 4-inch slab. You'll need 4.75 cubic yards for a 6-inch slab.
1.25 cubic yards for a 4-inch slab. 2 cubic yards (1.85) for a 6-inch slab.
The answer will depend on the size of the concrete block!
A 22x22 foot slab at a 4-inch thickness/depth requires a minimum of 6 cubic yards.
