    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 ...

    Maximum crushing strength is the maximum stress sustained by a board when pressure is applied parallel to the grain. Impact bending involves dropping a hammer of a given weight upon a board from successively greater heights until complete rupture occurs. The height of the drop that causes failure provides a comparative measure of how well the ...
