20%
Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours
That may be strength specific and will be subject to air entrainment

The weight of concrete is determined by its density, which is typically around 150 lbs/ft³. However, the density of concrete can vary depending on the type and amount of aggregate used, as well as the water-to-cement ratio. Additionally, the weight of concrete can also be affected by the compressive strength of the concrete, with higher strength concrete often weighing more than lower strength concrete. Therefore, the weight of 6,500 psi concrete can vary, but it is typically around 150 lbs/ft
The strength will vary depending on the type of concrete, the base, and the presence or absence of steel or fiberglass reinforcing.
ranges from 26 to 28 KN/mm2
Steel is heavier than concrete for the same volume, however steel buildings are generally lighter. This is because steel buildings utilize high strength of steel, so volume of steel in steel buildings is much smaller than volume of concrete in concrete buildings. In another words in steel buildings much less volume of material is needed for the same strength compared to concrete buildings.
