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.
The weight of a 6-inch concrete hollow block typically ranges from 28 to 36 pounds (approximately 13 to 16 kg), depending on the specific mix and density of the concrete used. These blocks are designed to be both strong and lightweight, making them a popular choice in construction. Variations in manufacturing processes and materials can slightly affect the weight.
For a 4-inch depth: 4.75 cubic yards. For a 6-inch depth: 7.1 cubic yards.
Approx 10.3 US gallons.
You can't express a volume of concrete in yards.
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!
