single type of low strength solid concrete block and a single classification of mortar. VARIATION OF COMPRESSIVE STRENGTH WITHIN THE MASONRY BLOCK MATERIAL Prisms measuring 50 mm by mm by 100 mm were cut from concrete masonry blocks and tested, in the air-dry condition, for compressive strength,
We have two options for accomplishing this. One is the unit strength method and the other is testing masonry prisms for compressive strength. The unit strength method verifies the compressive strength of the individual materials and then uses tables to determine compressive strength of the assembly from that information.
Why Compressive Strength Test of Concrete is Important? The compressive strength of the concrete cube test provides an idea about all the characteristics of concrete. By this single test one judge that whether Concreting has been done properly or not.

For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f’ m of 1750 psi to 2000 psi for CMU units with 2000 psi compressive strength). The compressive strength of the masonry units is the largest factor, by far, in masonry assembly compressive strength.
IS: 2185 (Part 1) – 1979 2 and IS: 2185 (Part II)-1983 3 specified Gypsum Plaster capping for concrete Blocks compression testing. The codes specified that, gypsum plaster, when gauged with water at the capping consistency shall have a compressive strength at 2-hour age of not less than 25 N/mm 2, when tested at 20 mm cubes.
Yi(2014) studied the compressive strength of double H concrete block masonry prisms under uniaxial compression. He discussed the effects of mortar strength, grouting and grout strength effect on compressive strength of the prism. The test result shows that the compressive strength of H block prism decreased with an increase of grouting and the
