    CMU Basics Strengths: Part 1 Angelus Block

    f' m, specified compressive strength of masonry, is the value used in design of the masonry wall. This is the strength specification that really matters, as it is the strength upon which the structural design is based. Notice it is the strength of masonry, not units. It is the compressive strength of the assemblage of masonry units, mortar, and grout.

    Apr 22, 2005· 7 Days Compressive Strength of Concrete 2. In general, using Type I Portland cement, you can expect about 65 to 70 percent of the 28day strength in 7 days. Not to many consistently reliable estimates for 14day strengths, since it isn't usually a measured parameter. Many reactions affect the strength gain of concrete, so you really need historical data on the mix you intend to use.
