min and max crushing strength of bricks

Natural stone strength (compression, bending, and abrasion) test

Compressive strength test. This test is vital for evaluating the stone’s resistance to crushing loads. A wall stone has to bear the compressive load of the stone’s weight. A stone floor has to withstand loads of people and heavy objects. So, compressive strength is the highest load per unit area borne by the stone without giving in.

Is the compressive strength of mortar important? | Masonry

ANSWER: Compressive Strength. In load-bearing masonry, mortar compressive strength may have some importance, but mortar only contributes a small amount to masonry assembly compressive strength (f' m).). For ASTM C90 concrete block, the assembly compressive strength only increases 250 psi when the mortar is changed from Type N to Type S (from an f' m of 1750 psi to 2000 psi for CMU units
