Where are 12 inch concrete blocks applied?
Two triangles
TVs are measured diagnally from corner to corner.
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
27 lbs
Normal Weight Concrete at 150 pcf has an R value of 1.22 per inch thickness
You can't express a volume of concrete in yards.
If you want to know the volume of blockfill for 8 inch blocks its 120 blocks to the cubic metre of concrete
1,000
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 .
A base in MLB is a 15 inch square. Going from one corner diagonally to the other corner would be a distance of 21.21 inches.
