CMU Basics Strengths: Part 1 Angelus Block

Strength, as associated with cmu, is expressed in two distinct values: Cmu compressive strength is the psi calculated from the net area of the individual unit. The minimum average net compressive strength per ASTM C90, as of the 2014 edition, is 2000 net psi. Previous editions of C90 indied 1900 net psi.
