Stone used as coping at the edge of a pool needs to be very durable and therefore should be Grade A or better. Durability is also associated with strength. Both compressive and flexural strength are related to the bonding of the minerals that make up the stone.

8. STRENGTH OF SOILS AND ROCKS

The tensile strength of soil is very low or negligible and in most analyses it is considered to be zero. In contrast a number of direct or indirect tensile strength tests are commonly carried out for rock. In a direct tensile strength test a cylindrical rock specimen is stressed along its axis by means of a tensile force.

Compressive Strength. Compressive Strength is the stress, in pounds per square inch (psi) that will rupture a stone sample. Very rarely is the compressive strength of a stone much of a factor in stone selection. A column of stone with a density of 160 lbs/cf that is 100 feet tall exerts a compressive stress of only 110 pounds per square inch.
