Soil in foundation mix

[Tennentslager]

I’m concreting in 4 big posts for my gazebo and have a load of ballast from digging up path edges which had decorative stone edges.

its a mix of stones and sharp sand and a little soil and odds bits of detritus 

is this okay to add cement and use like postcrete?

other than some soil ( not a lot) I’m thinking this will work?

It should be fine 

Mix it dry and add water once the posts are in place
