Q: Pick up the correct statement from the following
  • A. Density of normal concrete is about 2400 kg per cubic metre
  • B. Density of light weight concrete is about 1900 kg per cubic metre
  • C. Density of heavy concrete is about 3580 kg per cubic metre
  • D. All option are correct
Correct Answer: Option D - Density of concrete is a measurement of it unit weight. Density of reinforced cement concrete (RCC) is 2500 Kg/m³ or 25 kN/m³ . • Density of normal weight concrete is 2400 Kg/m³ or 145 lbs/ft³ or 24 kN/m³ .
