What is this moasnry unit.

What is this moasnry unit.

What is this moasnry unit.

(OP)
Please see attached picture I took for an existing masonry wall. I think it is Terra Cotta but not sure. Does anyone know this? Also, do you know what kind of tensile strength this type of unit has? I am trying to place some anchor in it.

Thanks,
 

RE: What is this moasnry unit.

These appear to be a fired clay based unit.  As far as anchoring to them, they are typically extremely brittle.

Does the other side appear smooth perhaps even glazed?

Thanks. I have not gotten a chance to take one unit off and see the other side. What difference will it make if the other side is smooth vs not smooth? Thanks again

RE: What is this moasnry unit.

It would have only confirmed the material type.

RE: What is this moasnry unit.

If its not cladding it looks iffy as a base material to anchor an expansion or epoxy type bolt into... I would consider a through rod(s) with backer plate, or have a traditional bolt tested in the field.

RE: What is this moasnry unit.

looks like structural clay tile that was used alot before CMU.

RE: What is this moasnry unit.

archeng59 has it right...It's structural clay tile.

RE: What is this moasnry unit.

(OP)
Thanks. Do you know where I can find some mechanical properties of the structural clat tile?

Ok, I found it in Brick Tech notes 3A...
