Concrete Failure Challenge

Concrete Failure Challenge

Concrete Failure Challenge

(OP)
Say, theoretically, that I had a lot of big chunks of concrete that I wanted to turn into a lot of little chunks.  I know pounding on them with a sledge hammer would accomplish this, but is there anyway to 'tenderize' these chunks before pounding?  Any possible chemical application or process that would weaken the cement bonds?  Could intense heat work? If so, how high would the temperature have to be and for how long would it have to be applied?  

 

RE: Concrete Failure Challenge

Chemical reaction would likely only affect the cement component and would not completely break it down before the reactant is consumed...not practical.

As for heat, you need about 600 degrees celsius for about 4 hours to start breaking down the bond.

Run it through a crusher.

RE: Concrete Failure Challenge

Agree with Ron :D ...BUT, depending on how many SY / tons of material, save yourself the thought process; you may be lucky enough to contact your local general contractors to have them remove for free for their own crushing operations for use as PGE or CA6 blending.

 

RE: Concrete Failure Challenge

We use Italian Dressing (vinegar and oil) to tenderize and marinate our steaks....oh wait...concrete....never mind.

JAE...best answer of the day...maybe the week!

RE: Concrete Failure Challenge

Actually, as vinegar is acidic, it would probably work on concrete as well, just cut out the olive oil!

RE: Concrete Failure Challenge

With most cement operations, they use rotary kilns with ball 'crushers'...
