Heavyweight Concrete. Heavyweight concrete is made from aggregates with a density between 2,080 and 4,485 kilograms per cubic meter (or between 130 and 280 pounds per cubic foot). These aggregates are much less porous and absorbent, and the resulting concrete has a higher mass-to-volume ratio.

Effect of Cube Size on the Compressive Strength of

Most commonly, the compressive strength of concrete is mea-sured to ensure that concrete delivered to a project meets the requirements of the job specification and for quality control. For testing the compressive strength of concrete, cylindrical test speci-mens of size 4 × 8-inch (100 × 200-mm) or 6 × 12-inch (150 × 300-

To price reduce the low strength results you need to know the bid price for the concrete, and the quantity represented by each test. As stated above, the concrete was bid at $700.00 per cubic yard. The contractor placed 720 cubic yards of Concrete Class D (bridge). The 720 cubic yards are represented by 8 sets of cylinders.

Concrete is generally sold in cubic yards. Since the measurement is currently in cubic feet, you need to convert that to cubic yards. Do this by multiplying the cubic feet by .037037037. 297.92 cubic feet x .037037037 = 11.03407406 cubic yards. Concrete used for this type of footing must be between 2,000 and 5,000 psi in compression.

Knowing a concrete pad's thickness or depth is vital if you need to determine the load it can withstand. If the concrete pad is two-inches thick and the concrete manufacturer's stated compression strength is based on that thickness, then you can simply multiply the area by the stated psi to determine how much weight the pad can bear.
