Outdoor toilet advice needed

[Dynamitebloke]

Hi, I decided to sort out our outside toilet. I removed the existing toilet however there are two issues which I want a bit of advice on..

Firstly they concreted the old toilet into place so now I've removed it im left with a mound of dried concrete, I've removed some of it with a cold chisel and a hammer but it's taking ages, any ideas on a cheapish tool that would make this easier..

Also, it looks as if they've cemented the porcelain waste pipe of the toilet to the waste outlet so I had to break it off and now I'm left with this rim of porcelain and I can't shift it.. any ideas on how I shift this, do I even need to, the holes open diameter is 85mm..

Any help would be appreciated..

Edit.

I thought you wanted to dig it all out. Sorry about that.

Just drill holes in the concrete then chisel out.

You can get pan connectors for that size or chip out the porcelain ( push a carrier bag full of paper just inside to prevent debris falling in)

I've tried everything to remove the porcelain and I'm not even making a dent . If I can get a pan connector that size, think I'll have to do that...
