How much weight can concrete hold before breaking?

The weight that concrete can hold before breaking depends on factors such as its composition, thickness, and the conditions it is exposed to. On average, concrete can typically withstand compressive strengths ranging from 3,000 to 7,000 pounds per square inch (psi) before failing. However, it is important to consult with a structural engineer to determine the specific load-bearing capacity for your particular application.

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
