CMU Unit Strength Method Calculator

The NCMA Concrete Masonry Unit Strength Method Calculator is a spreadsheet-based calculator tool to aid in determining either:

  1. The specified compressive strength of masonry for a given CMU strength, or
  2. The required CMU strength for a given specified compressive strength of masonry.

The calculator provides these values in accordance with either the 2013 or 2016 version of TMS 402/602, Building Code Requirements and Specification for Masonry Structures.
