Specified Compressive Strength of Concrete Masonry, f’m ...

According to the Code this would require a block compressive strength of 1900 psi. Recently on projects, some designers are now specifying a higher f’m, i.e., 2000 psi, 2500 psi and 3000 psi with Type S mortar. According to the Code this would require a block compressive strength of 2800 psi, 3750 psi and 4800 psi, respectively.

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 ...

ASTM SPECIFICATIONS FOR CONCRETE MASONRY UNITS -

The net area used to determine compressive strength is the “average” net area of the unit, calculated from the unit net volume based on tests described in ASTM C140 (ref. 4). Gross and net areas are shown in Figure 1. Net area compressive strength is used for engineered masonry design, taking into account the mortar bedded and grouted areas.

In the case of 9 inches block the compressive strength is 2.59 N/mm 2 and 3.94 N/mm 2 for ages 7 days and 28 days respectively. This shows that there is a variation in compressive strength between the two blocks. To this end, it can be deduced that the strength of 9 inches block is more and higher than that of the 6 inches block.
