WHAT IS a good concrete to use for karate breaking demos?

Question

need to put on an impressive demo, can break concrete, but is there a special mix/any tricks to make the concrete break easier?

Answer 1

To break concrete is the way you prepare it. Get a light concrete block with air holes in. Make it set and allow the mosture to escape. Then you heat it up, then freeze it.

This heating and cooling will allow miniture cracks to appear in the concrete. It will fracture upon impact and will look good for demonstrations. Spacings also should be used. The larger the spacing, the more the energy is lessened through the material. But too little spacings and the block becomes a large block making it less likely to break.

So make it light, heat it up and freeze it. Soak in water and freeze again. Do it a few times until it is ready and then do the demonstration. Martial art demos are all bravado as noone can really break a concrete block straight from the yard by hand.

Answer 2

WHAT??? If you are a doing an "impressive demo" why do you want something easier to break? How impressive is your demo if you have somehting that is easy to break? What exactly is this supposed to prove? I don't remember reading about the ancient founders of karate breaking materials ( or materials that are rigged to break easier). It seems silly. You may want to re-think your training.

But to answer your question I recommend you use styrofoam spray painted to look like concrete. (Like the fake grave stones at halloween) They look real. This way your hand won't even get scratched and your hits will look real impressive.

Answer 3

upt you hand through eigth inch thick plating preferably a nickel steel compress cause your cahnces of punching through that are higher tahn punching through a concrete. Human anatomy is flawed being our bones. Our ivor no matter how hard we train or drink the right nutrients can not be hard enough to break compacted cement. So if you can punch through a brick good for you bu the chances of you not hurting yourself is stupid. why not do a demo f skilsl you know set up trainign course and do it not be like hey look i'm a moron breakign a brick!

Answer 4

actually breaking concrete slab is real easy. We just did a demo a few months back and even young teenagers were breaking it there very first time. They were only white belts too. Stay focus and breathe and FOLLOW THROUGH!!!!!!!
