* These are laboratory tests according to ASTM C-270 and are simulating the strength in the wall-not in the mortar tub. Field tests from the mortar tub will be lower due to the fact that more water is added (See ASTM C-270-99 section 3 and Note 3 after section 5).

* Bond strength tested according to ASTM C-1072
