#89 Stone vs Mexican Beach Pebble: Size, Cost, and Which to Use

#89 Stone

In the ASTM C33 sieve table, #8 stone passes a 1/2-inch screen and stays on a #8 sieve (about 3/32 inch), and #9 is a step finer. #89 is a blend of the two: most of it passes a 3/8-inch screen and stays on a #16 sieve. In practice you get a clean, small, sharp stone that looks like crushed pea gravel. Some quarries sell the same product as #8, #9, or "3/8 clean."

Mexican Beach Pebble
