Non-Explosive Demolition FAQs

Here's some tips & frequently asked questions on how to find the right chemical cracking for your job

1. What is non-explosive demolition?

A non-explosive demolition agent is a chemical used as an alternative to conventional explosives or gas pressure blasting products during demolition, mining and quarrying. Normally, its active ingredient is calcium oxide "burnt lime" that is mixed with some Portland cement and possibly other modifiers.

The use of non-explosive demolition agents begins by drilling holes into the base of the rock, just like drilling holes when using conventional explosives. The slurry mixture of the agent plus water is then poured into the drill holes. This slurry mixture will expand over the next few hours. The rocks will crack as a result and in a pattern similar to the cracks that would occur when using conventional explosives.

Although in some cases, the conventional explosive is preferred and more economical, here are some advantages of non-explosive demolition:

  • Noiseless.
  • Safe.
  • Does not produce vibration.
  • It is available without much restriction in various countries, unlike highly regulated explosives.
 

2. How do you break a rock easily?

Below are three methods you can use to break a rock easily without resorting to conventional explosives.

  1. By sledgehammer. The first step of this method is to place the rock on a flat surface, if possible. Next, pick a point on the rock that you will hit without much difficulty. This is where you will apply repeated pressure later to force it to crack. Make sure to hold the sledgehammer correctly before swinging it a full 180 degrees to hit the specific point in the rock. Start slow and continue hitting the same spot. When you see a small fault line on the surface, that is a sign that you are close to breaking the rock.

  2. By regular hammer. If you plan to break a small rock, then this is an excellent method to use. Find a larger canvas bag and put the rock inside. Make sure to tie it close. Next, lay it on solid ground and try applying firm pressure to it, so you are assured that it will not move around. Knock the rock gently at first, practising the swinging motion with the hammer to get the gist of what you are about to do. Start hitting the casing in precise points. Do this with progressively harder pressure until it cracks. When the job is done, be careful in opening the bag immediately because of the resulting dust inside it.

  3. By splitting. In this method, you will need a drill to create evenly spaced holes on the surface of the rock. The following tools you'll need are chisel and feathers that you will drive into the holes. Finally, you can start breaking the rock by hammering on the chisels. When a large crack appears, pry it open with a crowbar.

 

3. How expensive is non-explosive demolition?

There are many non-explosive demolition powders available in the market, all varying in prices. For instance, ECOBUST, a rock and concrete breaker product from Neoferma Australia, costs around $80.00 for 20kg. Each product and its installation can greatly vary in price depending on the project size.

 

4. What is chemical cracking?

Chemical cracking is the process of complex organic molecules being broken down into simpler molecules by breaking the carbon to carbon bonds in the precursors. For instance, breaking down long-chain hydrocarbons into light hydrocarbons. The speed of chem cracking is usually dependent on the temperature and the involvement of catalysts. Typically, it is a process that will require high temperatures.
