The compressive strength of a wall depends on the strength of the units used, the bricks or blocks, and the mortar. The assessment of the combined strength of the elements will also be affected by the degree of quality control exercised in manufacture and construction.

Verifying Compressive Strength of Masonry cement

We have two options for accomplishing this. One is the unit strength method and the other is testing masonry prisms for compressive strength. The unit strength method verifies the compressive strength of the individual materials and then uses tables to determine compressive strength of the assembly from that information.

Tech Talk: Recent Changes to ASTM Standards and Code for

With a Type N mortar in the old (2011 and previous) Code, in order to provide an assembly compressive strength (fʹ m) of 2,000 psi, the concrete block strength needed to be 3,050 psi. Now, a 2,000 psi fʹ m only requires the block to be 2,650 psi. The NCMA research also recommended a new minimum concrete block compressive strength of 2000 psi.

FAQ 05-14 Answering Frequently Asked Questions An

illustrates the correlation between unit compressive strength, mortar type, and assembly compressive strength. Increasing the final design strength of masonry assemblies has not been the only recent change. In 2014, ASTM C90 was revised to increase the minimum compressive strength of a unit from 1900 psi (13.1 MPa) to 2000 psi (13.8 MPa).

Top Tips Compressive Strength v Density
