Correctly built and designed, the compressive strength of CMU block walls provide good support for the vertical loads on foundation walls. The Cons of Cinder Block (CMU) Foundation Concrete masonry units are heavy to handle. 8-in blocks weigh 36lbs, 10-in blocks weigh 42lbs.

Density vs Strength: There's a Difference - Basalite CMU

Jul 24, 2018· The Compressive Strength of CMU is measured in "pounds per square inch", ("lbs/in2" or "psi"). Among the combined strengths of the aggregates, sand and cement, the more important influence on overall compressive strength is the quantity of cement used in the mix, and the time allowed for the block to cure.Generally, the higher the cement content, the higher the strength, and, the ...

ASTM SPECIFICATIONS FOR CONCRETE MASONRY UNITS - NCMA

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.
