How thick a concrete wall would be needed to give the same insulating value as 3 and a half inches of fiberglass?

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

What does an 8 x 10 x 16 concrete block weigh Is there a difference between a concrete block a concrete cinder block?

It weighs 59 lbs. There is a difference between a "real" cinder block and a concrete block. A cinder block uses cinders--ash from the burning of coal--as its aggregate. Concrete blocks are made from concrete. Concrete block is far stronger than is cinder block, and some jurisdictions prohibit the use of cinder block. The only justification for cinder block is that it weighs less than concrete block, which is important if the ground you're building on isn't strong enough to support a heavy structure. This justification has gone away, because now you can buy concrete block made from expanded-shale aggregate that's as light as cinder block and as strong as standard-weight concrete masonry.
