The compressive strength of the rock used is almost always equal to or greater than concrete. The mortar used will typically be a type of portland cement and will be weaker than the rock. Stone masonry deteriorates by weathering breaking into small particles spalling small sections of rock popping out or splitting separations occurring either at seams in the rock or along mortar joints .

### Stress mechanics - Wikipedia

If the normal unit vector n of the surface pointing from Q towards P is assumed fixed the normal component can be expressed by a single number the dot product T & 183; n. This number will be positive if P is "pulling" on Q tensile stress and negative if P is "pushing" against Q compressive stress The shear component is then the vector T − T & 183; n n .History& 0183;& 32;
