Front door Canopy Crack

[ukmercenary]

So I noticed the other day that my concreate Canopy has two rather worrying cracks on it.
I messaged by builder/DIY handman and he said 'they are made from reinforced concrete which looks like it’s suffering concrete cancer this is where the re-bar rusts and swells then cracks the concrete.' he is going to pop over later to advise.

I have also posted a job on the My Builder app.

I don't think this would be an easy job for me. The concreate looks very heavy and working at hights also.
I not sure what my options are with this any ideas?

It needs to come down. What you do afterward is your choice, but it doesn't really look deep enough and seems to be too high to be effective.

I very much doubt it's "concrete cancer" which is the popular name given to AAR (alkali aggregate reaction) which is a specific and mercifully rare condition. Water getting into cracks and rusting steel is all too frequent where cover is inadequate and/or the concrete is inadequately compacted

TBH this looks as though it's had an excessive load applied to the end and it's broken

New build cancer?
