as per subject,will the both materials bond to each other successfully?

I've never had the means to try this and in my mind I don't think the two
are compatible to bond ie sandstone being a dusty/brittle material.

Whilst I'm sure portland cement will work, particularly on a softer
sandstone I would think lime mortar is a more suitable material. If the
sandstone is likley to be fairly weather exposed and prone to erosion,
even more so.

OPC bonds just fine. By all means use lime mortar if you have a
lifetime to wait for any bond strength....

Exactly what are you trying to do? Build a wall? Lay slabs? Renovate
something?

Sandstone binds very well to mortar

Use either. Harder bond with portland.

Bricks are a more solid material,whilst a 120 year old sandstone
block(exposed to the elements is not). :-)

Renovate, not me doing the job but the guy is bonding a brick surface to
sandstone using cement as the bonding to seal a leaking bay roof?

Depends on the brick.

Sorry, I still don't understand. Is the brick surface a wall? Where
does the sandstone come into it? Is the mortar just applied as a
fillet, or what? Describez-vous, sil vous plait (sorry!).

Where the sandstone edge part of the bayroof meets the facing brickwork.
I suppose you would call it a fillet,and personally I reckon this area
should have been done with flashing and he's just doing a cock up job of
sand and cement and coming back in a couple of days to apply some bitumen
over the job?

Should be ok if any crumbly stuff is brushed off first.

Has the bay got some sort of parapet, then? You put some pictures of
plumbing up a while ago, can you get a picture of this?

Sounds like it...

Possible, but wouldn't like to try and say for sure.

How sad a job is this.

Sandstone is really quite variable.
It goes all the way from something you can hammer on with impunity, to
something you can poke gouges in with your finger.

Like bricks, then ;-)
