Frogged bricks

[akist]

Is the cavity in frogged bricks present to reduce the amount of clay needed to make them? But it is then substituted with mortar so isn't that the same?

Or is it present to increase the surface area the adhesive mortar will join to (and a wedge) and thus achieve a better joint and more resistant to lateral forces?

All I know is that the mortar is there to keep the bricks apart and that a fishing net is a load of holes tied together with string.

No, it is to keep them together.

Lol. W....T......F......F?

Ok, the paramedic has been and strapped my sides.

Imagine scraping a bit of unnecessary clay from a brick-shaped lump, so that every 5 lumps of clay you can make six bricks. And it makes the brick lighter for the poor chap laying them into the bargain.

I understood the frog indent in the brick mould forced the clay into the corners.

But holes are frogs too.

Nope it's to keep them apart, the strength is in the bond, not the mortar

Why is mortar so sticky then?

Why is mortar so sticky then?

It needs to stay in place whilst keeping the bricks apart.

Can I cut up some OSB into spacers to keep the bricks apart, instead of employing a labourer to mix the compo?

It's there for many reasons, some of which not even brickies with 40+yrs of experience can ever hope to understand, so it's pointless going into them in any depth here

Is it not a glue?
