What material is this

[usn90]

found this on my driveway, looks like slate but not sure what the strands are, fibreglass?

No idea where it’s come from and what it’s off which is bugging me.

Probably a fibre cement slate.

Quite common as a cheeper alternative roofing to real slate.

Yes thinks your right, just looked at some on the internet

Thanks
