Hello!
I need to brick/cast over a hole in the chimney breast and also even out and repair after chiseling out a new hole.
I can put a support on the back of the hole that needs to be bricked/cast over since there is an inspection hatch next to it. Should I use bricks as much as possible and brick it up, or should I cast over with something like concrete?
A friend told me I can use concrete (I have a 0-6 sack) even if I’m bricking it up with bricks, and I can also pour in some primer (adhesive) into the mix since I have some leftover.
Tips/advice are gratefully received!

Is there no mason here? 
What I'm wondering is what distinguishes mortar and concrete. I realize that it's more difficult to lay with concrete because the stones get damaged during the actual paving, but that's not a problem in my case, and it's not particularly coarse concrete either.
I believe in concrete because it's probably better for filling in, but are there any disadvantages, such as it cracking more easily during the curing process?
Thanks in advance!

Brick and C-bruk.
It ended up being concrete after all, and I think it went well.
I didn't use any stones at all but instead filled the hole with concrete. It was a bit tricky to get the concrete dry enough so it wouldn't flow away and at the same time wet enough to adhere. I made dry concrete and sprayed with water where I needed it to adhere. It worked well, but it would have been fun to see how a pro would have done it
