Is this coarse clay?

[edwardyeeks]

I got this 'soil' from a construction site near my house. Is it course clay? It feels like plasticene, yet it crumbles too. Plus it feels 'course'

The 'soil' was rather compressed since the area where I collected the 'soil' from was already flattened and hard. But I dug my way through.....

And of course, I asked permission of the workers there. They stared at me as if i was weird and said ok.

Thanks in advance for helping and I would appreciate any help from anyone of what to do with the 'soil' if it is course clay. I may be getting northiana soon.

Cheers
