Breaking up Concrete Slabs and Concrete Edging for hardcore - asbestos?

[RonK]

Hi,

It's too late now any way as I've already broken up a lot of this stuff!!! I'm certain it's fine but thought I'd check - can concrete slabs or concrete edging contain asbestos? It seems unlikely but the interior of the slabs and edging is a blue/black colour that sparkles a bit like quartz. I think it's probably compacted fly ash or similar but thought I'd check. Photos attached.

Cheers,
RonK

Extremely unlikely

For one thing , drives don't often catch fire- so why?

Haha - very true! I just thought it was a weird looking interior to the slabs. Anally safety first I guess!

Thanks,
