Boulder Breaking, Rock Splitting and Cracking, Marble, Limestone and Granite Mining as well as Concrete Demolition has never been easier, safer and environmentally friendly than with Crackamite Non-Explosive Demolition Powder. Crackamite is a chemical mixture powder with super expansive strength when it is mixed with water. When this Crackamite mixture is filled into drilled holes, according to the appropriate hole design, Crackamite breaks apart concrete and cracks and splits rocks and boulders safely and quietly.

As shown in the figure on the right, place a thermometer in the bottom of the hole and leave it in place for 2-3 minutes. Then quickly pull out the thermometer and take a reading. Avoid taking temperature right after drilling since the temperature of the hole is higher because of friction heat. The temperature of the rock or concrete being broken is important first step.
Now we just have to wait for the gentle blasting. The mixture hardens slowly in the borehole and sets. The expansion pressure then gradually begins to build up. The fracture time depends mainly on the temperature, the borehole diameter and the borehole spacing. Cracking always occurs in the direction of least resistance. A larger drill hole diameter means more force, shorter reaction time and wider crack formation. Smaller distances between the drill holes mean smaller fragments and a shorter reaction time. As a rule, small hairline cracks are already visible in some places after a few hours. These then continue to widen and new cracks appear. Don&#;t make the mistake of starting to remove the fragments too early. It is best to let the product work for as long as possible, because with every hour it becomes easier to clear away or remove the blasted object. With a little experience, the blast pattern and blasting time can be predicted very accurately and almost all blasting work can be carried out explosion-free.
You will get efficient and thoughtful service from Sanqiang Building Material.
Tip: BETONAMIT continues to expand over several days. This means that the more time you give the product, the easier it is to remove the fragments. Therefore, be patient and allow BETONAMIT to work for as long as possible to achieve the best result.
Please observe our safety regulations when handling Betonamit.
