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 7N/mm 2 blocks in aircrete - medium density and dense aggregate blocks for instance. When choosing the right block type to use, it’s therefore important to consider the requirements for sound insulation

In Simple words, Only 5% chances are there that the concrete will fail at its characteristic strength. If a block of M25 concrete has a characteristic strength of 23 MPa means that the chances of failure are only 5% at that load(23 Mpa). 95% chance is there; it will survive. The compressive strength test will be determined by the strength of concrete at 28 days as per IS standard. Based on the
