In building low walls out of concrete rubble for landscaping ( like the walls of a planter, not walls of a building), what is the best binding material? Should I use more concrete to bind the chunks of rubble? Should I treat it like a brick or stone wall and use mortar?
Use mortar.
The mason who did the replare and extension of the wall bordering the patio at our old property used mortar. The faces were the nice limestone rock from the old stone walls on the back of the property and he filled the inside with "whatever fit".
I would dry fit, with tumblehome, to allow drainage.
Or buy some K rail

Building a wall outa "concrete rubble" sounds like a creative and interesting idea. you don't say but im assuming this might be from a concrete slab and the bottom unfinished side of this "rubble" will become the decorative face side of the wall....
I would use a mortar (type "S"). I think type s has some polymer additives to help with expansion and contraction caused by heat and cold cycles o'l Mother Nature throws at us ..so it shouldn't crack up as bad as a concrete mix.
sounds cool, good luck with it!
Will it freeze, any water behind the wall.

Freezing comes into play if there are cracks in the construction or voids that can receive water. A properly constructed wall should be quite durable as long as it's maintained.Quote:
