The density of ordinary concrete is 2000-2800Kg/m3, which means the weight of concrete per cubic meter is 2-2.8 t.
Although different concretes have different specific weights, the weight of each type of concrete will not differ much.
For example: one side of plain concrete is 2.35 tons, one side of reinforced concrete is 2.4 tons, and one side of ordinary concrete is 2.35 tons.
Generally, the apparent density of gravel is 2.5~2.53, and that of cement is 2.9~3.1. Just calculate it according to the mix ratio you have. Regardless of steel bars, the density of concrete is generally 2.45~2.55. In rough calculations in civil engineering, C20~C35 concrete is generally 2.45t/m3. If it is an accurate calculation, it is necessary to separately measure the apparent density of various gravels and cement density, and then calculate it according to the mix ratio considering the hydration loss.
