liquid concrete breaker
You're right and the one product I have used is Dexpan and there is one other, but it you Yahoo/Google it you will find what youre looking for.
Not cheap, but good stuff. I broke apart my porch slab that was a "hunk" of concrete and it took about 3 holes and a gallon of the liquid breaker to take care of the porch. What a good time that was. The hunk was about 5'x3'x4'. The breaker busted it up in no time. I finished it off with a prybar. Enjoy.
Wedges and feathers work just as well.
And you are not buying material that you are just throwing away.
If ya live where it freezes hard in the winter, palin ol' water will work.
FFFg black powder pours fairly well also.........
