Strength characteristics of stone masonry | SpringerLink

The compressive strength of stone has been determined through 80 mm size cubes. It has been found that the compressive strength of granitoid-gneiss is greater when the load is parallel to the mineral bands. The compressive strength of stone masonry was studied through masonry prisms using 1∶4 and 1∶8 cement mortars.

Brick Masonry Material Properties

The material properties of mortar which influence the structural performance of masonry are compressive strength, bond strength and elasticity. Because the compressive strength of masonry mortar is less important than bond strength, workability and water retentivity, the latter properties should be given principal consideration in mortar selection.

How to Choose the Right Mortar Mix: N, O, S, or M

Type N mortar mix has a medium compressive strength and it is composed of 1 part Portland cement, 1 part lime, and 6 parts sand. It is considered to be a general-purpose mix, useful for above grade, exterior, and interior load-bearing installations. It is also the preferred mortar mix for soft stone masonry.

The Importance of Testing When Specifying Natural Stone

The Materials Specifications put forth minimum values for compressive strength for each stone type; for example, at least 1,800 psi (12.45 MPa) for marble and 19,000 psi (131 MPa) for granite. Compressive strength—or the load at which the stone fails—is usually much higher than the actual load the stone must resist.
