The concrete calculator is calibrated to exactly 23.60 kN/m3 unit weight per concrete volume. Which is, as Internationally defined, how heavy is normal reinforced concrete. In USCS units (United States Customary System units), its weight comes to ~150lb/ft3 and ~2,400 kg/m3 if measured in Metric SI system.
If I still remember my American Concrete Institute (ACI) manual, a concrete can withstand a compressive stress of 2000 pounds of load per square inch. This is wahta they referred to as Class A concrete, with a mixture ratio of 1:2:3 of stone:gravel:cement mix.est Answer: You didn't give units of area for me to work with, but I will tell you what I can. Medium strength concrete would fail at about 28 MPa (4,000 pounds per square inch).
