    ASTM C90, Standard Specification for LoadBearing Concrete ...
    ASTM C90, Standard Specification for LoadBearing Concrete Masonry and solid loadbearing concrete blocks are covered in this standard. Weight classifications are divided into Light Weight (less than 105 lb/cu ft oven dry weight of concrete), Medium Weight (105 to less than 125 lb/cu ft), and Normal Weight (125 lb/cu ft or more).

  • Concrete Block Vs. | Hunker
    Concrete Block Vs.  | Hunker
    According to the Masonry Advisory Council, all concrete blocks must have a minimum compressive strength of 1900 pounds per square inch. Many dense blocks are stronger than this. According to Mechanical Properties of Unreinforced Masonry, the average concrete block can withstand 3500 psi, while the average clay can withstand 3000 psi.

    Normalised Strength of Aggregate EPIC Concrete Blocks
    Concrete Blocks Aggregate Concrete Blocks Introduction Eurocode 6 (BS EN 1996) commonly referred to as EC6, replaced BS 5628 as the UK masonry design code on 1 April 2010 when BS 5628 was withdrawn. EC6 differs from BS 5628 in that it requires the Normalised strength values of units to be used in design calculations rather than the unit strength required by BS 5628.

    f' m, specified compressive strength of masonry, is the value used in design of the masonry wall. This is the strength specification that really matters, as it is the strength upon which the structural design is based. Notice it is the strength of masonry, not units. It is the compressive strength of the assemblage of masonry units, mortar, and grout.
