Thomas Armstrong's Concrete Block Technical Guidance provides advice on concrete block strength, compressive strength and storey height. Our concrete blocks are suitable for use in meeting the UK structural Building Regulations and codes currently in use including Approved Document A of the Building Regulations, BS 5628, BS EN 1996-1 and BS 8103.
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 ...
