SAMPLING AND TESTING CONCRETE MASONRY UNITS - NCMA
The unit compressive strength results may also be used to verify compliance with the specified compressive strength of masonry, f’ m, when using the unit strength method (ref. 4, Article 1.4 B.2.b). Unit compression tests are easier and less expensive to perform than similar tests on masonry prisms, making the unit strength method the more
Compressive strength - Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled

COMPRESSIVE STRENGTH TESTING VARIABLES FOR CONCRETE
Figure 2 illustrates the effect of aspect ratio on apparent compressive strength of solid specimens. Hollow concrete masonry units are less affected by variations in h/t. For example, research has shown little change in apparent compressive strength when the unit height is reduced by one-third or less.

Compressive strength - Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate.In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). In the study of strength of materials
ASTM SPECIFICATIONS FOR CONCRETE MASONRY UNITS - NCMA
Units are required to be at least 5 in. (127 mm) thick, with a minimum gross area compressive strength of 2,500 psi (17 MPa) (average of 3 units) or 2,000 psi (13 MPa) for an individual unit, and a maximum water absorption of 10 pcf (16 kg/m³) (average of 3 units). The overall unit dimensions must be within ± 3% of the specified dimensions.

How to Calculate Compressive Strength | Sciencing
Compressive strength involves testing and calculating how well a given specimen, product or material can survive compressive stress. Unlike tension, which expands or pulls, compression means a specimen, product or material is shortened or pressed down. Compressive strength of a material is the point at which the
