Concrete compressive strength for general construction varies from 15 MPa 2200 psi to 30 MPa 4400 psi and higher in commercial and industrial structures. Compressive strength of concrete depends on many factors such as water-cement ratio, cement strength, quality of concrete material, quality control during the production of concrete, etc.
The compressive strength of a block is not directly related to its dry density. Indeed, there are a wide range of options when it comes to considering which block to use. You can get 7Nmm2 blocks in aircrete - medium density and dense aggregate blocks for instance. When choosing the right block
