What is the average density per cubic meter used for calculating the density of concrete?

• A. 2100 kg
• B. 2500 kg
• C. 2600 kg
• D. 2400 kg

Answer: (D)

The amount used for calculations is 2400 kg per cubic meter because normal-weight concrete typically has a density around 2.2 to 2.5 t/m^3, and 2400 kg/m^3 is the widely adopted average for quick estimates. This means 1 m^3 of concrete weighs about 2.4 metric tons. Real densities vary with mix and moisture, and heavier or lighter concretes fall outside this standard range, but 2400 kg/m^3 is the common default for design and calculation.
