2200 kg/m3
2300 kg/m3
2400 kg/m3
2500 kg/m3
Answer is Right!
Answer is Wrong!
The correct answer is: 2400 kg/m3.
Reinforced concrete is a composite material made of concrete and steel. Concrete is a mixture of cement, water, and aggregates (sand and gravel). Steel is a strong, ductile material that is used to reinforce the concrete.
The weight of reinforced concrete depends on the type of concrete, the type of steel, and the amount of steel used. The density of concrete is typically between 2200 and 2500 kg/m3. The density of steel is typically 7850 kg/m3.
The weight of reinforced concrete is typically taken as 2400 kg/m3. This is a conservative value that allows for a range of concrete and steel densities.
The other options are incorrect because they are not within the range of typical concrete and steel densities.
