Crushed concrete

[bluedog225]

What are you guys think of crushed concrete for a pad instead of road base?

The fellow who hauls gravel tells me it is a more economical choice.

I have a dim memory of hearing about problems with it due to wire mesh and rebar. He assures me it’s a processed product with no steel in it.

I’d appreciate anybody who has some experience with this stuff

what kind of pad?

I've only messed with it once to fill potholes in a parking lot of my church... it had A LOT of fines... They washed out in short order. I didnt order the material otherwise I would have never ordered it... it was "cheap"... yea it was also "cheap" the 2nd time it was done.

I've used it a bit. Never any steel in it. It packs down nice if damp. I've thought of using it with additional cement to make concrete, it already has perfect proportions of gravel and sand.

I used it as a base for my shop - packed down great - no complaints.

PS: I'm picking it up and paying about $20/yard. That near Calgary, Alberta, Canada.

I was thinking as pad in front of the conex, or as a parking area.

I used crushed concrete for under my pad, it has been no issues . the best part was it was free , had to pay a bit for trucking .

crush concrete *****, although approve by highway department, its takes alot of sand added for it to meet graditaion, peop\le ask how do you compact crush concrete, add some portland cement to it

About any compactable granular material is fine for use as base material under your slab. In geotechnical terms the loads imposed by a slab on grade are quite modest. If crushed concrete is readily available and cost effective, carry on.

Depends on size you are using. Yes it is cheaper. Yes it works. Yes it will have metal in it no matter what the supplier says. Honestly, fines work great once the get damp and packed, will turn hard has concrete. When you use what we calls 3s, the larger 2"+ rocks, they do work well as a base but I don't like that they get rounded going through the crusher and don't lock together as well as a similar granite product.

I picked a few loads at the pit for my driveway maybe 12-13 years ago. Haven’t had any issues other than I should have got a few more loads. It’s pretty solid still, and hasn washed out. I’m gradually losing the crown from snow removal, but that’s to be expected.

If it’s available this spring when the pit reopens, I will use it for the base of a planned sauna.
