Properties of Concrete Blocks — Strength
In the use of concrete blocks for the walls of buildings, the stress to which they are subjected is almost entirely one of compression. In compressive strength well-made concrete does not differ greatly from ordinary building stone. It is difficult to find reliable records of tests of sand and gravel concrete, 1 to 4 and 1 to 5, such as is used in making blocks; the following figures show,Compressive strength of AAC Block - Test procedure,,Aug 26, 2020· The compressive strength of AAC block masonry is less than that of the compressive strength of individual AAC block.
