Reinforced concrete is concrete with steel rods or mesh embedded into the mix. While this is a stronger type of concrete than normal concrete, it has a similar density because the composition of the concrete mixture is roughly the same. This concrete has a density range of 2200 kg/m3 to 2500 kg/m3. 

The density of reinforced concrete mainly refers to the density of concrete. The density of concrete needs to be configured according to a certain ratio. The configuration also has certain requirements for the cement used in concrete.
Generally speaking, the bulk density of C10 to C20 grade concrete is between 2360-2400kg/m3, C25-C35 is generally about 2400-2420kg/m3, and C35-C40 is generally between 2420-2440kg/m3.
The general density of plain concrete is about 2200kg/m3. The general design density of reinforced concrete is about 2500kg/m3. The density of various concretes is different due to different aggregates, cements, configuration methods, and different amounts of steel bars.
