Tensile Bond Strength of Mortar to Brick
Tensile Bond Strength of Mortar to Brick
(OP)
Can someone tell me what the tensile bond strength mortar should have to the brick and where I can find it? Thanks!

To give a range of values, studies (by the Brick Institute) show that tensile bond strength can vary between about 15 psi and 100+ psi, with air entrained mortar being on the low side and non-entrained on the high side. Another factor is how well the brick is placed and tapped to leve...tapping increases bond, apparently because it removes entrapped air between the brick and mortar whereas hand pressure does not.
I would suggest that you contact the Brick Institute (now called the Brick Industry Association). They have a lot of technical resources....

There are so many variables and no way to accurately inspect, sample and test what the actual is, assuming zero is conservative and usually not punitive since the tensile bond strength is rarely a problem. For brick, the actual strength to pull 2 brick brick apart in tension is affected by more things than an idealized lab test of small samples. - Like suction rates of the brick, coring and frogs. For specific applications for anchorage details, creative testing of actual assemblies would be needed.
What is the area of your concern (beside a vague lab test result) for your real application?
