pea shingle for concrete?

[andrewf75]

Hi all,
Need to fill in a 10cm gap between pavers and house wall with concrete so that I can build a step on it. For making the concrete can I use the pea shingle that is already filling the gap? or should the aggregate be more crushed?
Thanks!

your pea shingle will be fine

nice one cheers, I'm thinking a ratio of 4 gravel/2 sand/I cement ?

3/2/1 would be better.

4/2/1/ can be very loose and hard to work with.

Thanks a lot
3/2/1 it is. Got a load of leftover sand and cement anyway so the more of that I use the better!
