Brick And Mortar

jshuatree8

saw on here a while back something about what type of brick goes with a certain kind of mortar was wanting to bring that up again and get educated on that .......also was wandering about the dead man ... can that be fationed with some thick rebar inserted into the side of the wall with some kind of anchor and may anchored into some mortar or concrete at the dead man side

I like to talk about mortar. Here are some basics.

Mortar should not be stronger than what ever it is holding apart.

Compressive strength is a term that should be used with concrete, not mortar. Bond strength is what counts.

Flexural strength and autogenous healing are enough reasons to use lime, but workability and board life are a nice bonus.

Some things you may not know.

Masonry cement is NOT portland cement with something added to it. It is a different product. The difference between Type N and Type S masonry cement is just under 4 pounds of the exact same material in the bag. There are packaged cements, labeled as "mortar" or "masons mix" that contain portland cement and lime, and they are usually mixed to type S porportions.

There is no accepted field test for mortar strength "off the board".

so are u saying that what is in the s type is the same exact mix that is in the n typw there's just more of it....?

Read the weight on the bag......

Tscar is correct, just mix a batch of type N light mortar and compare to a portland type 2 and half bag of lime batch,,, i perfer the portland /lime mix to the type N but ,, but if u need a small batch or two fast the Type N will do.

I've done deadmen that way in the past.They help hold the wall until it's backfilled.Keep in mind though the steel will eventually rust out and leave a void in it's place.

glavinized should prolong live of steel .
