Hi,
I want to repair some steps that are brick with a concrete layer on top. I've never done any concreting but reading around the subject, it doen't seem too difficult :)
Attached are two photos:
#1 shows the steps near the door which are OK
#2 shows the ones I'm trying to repair
I plan to remove all the loose stuff, place wooden formwork along the edges and pour some concrete in.
Questions:
The concrete is only 10mm thick and there is an overhang of 50mm - is this going to be too thin to be solid?
--------------------------- ^

10mm
What sort of concrete mix should I use - is there ready mixed stuff for small jobs like this?
Given the thin layer, what about the courseness of any aggregate? Can you use just sand and cement and skip the aggregate?Thanks
Tony
