Crackmax expansive mortar, stone cracking powder, Soundless Cracking Agent ( SCA ) are Non-explosive demolition agents, is to be commercial products that are an alternative to explosives and gas pressure blasting products in demolition, mining, and quarrying. To use non-explosive demolition agents in demolition or quarrying, holes are drilled in the base rock like they would be drilled for use with conventional explosives. A slurry mixture of the non-explosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands, cracking the rock in a pattern somewhat like the cracking that would occur from conventional explosives.
Stone Cracking Powder (Normal type), for stone quarry, such as granite, sandstone and marble with free surface. The max pressure will be 15Mpa.

Soundless Cracking Agent is a non-explosive demolition agent that has the ability to safely demolish rocks and reinforced concrete, cement without producing noise, vibrations, debris launches or environmental
pollution, To carry out the demolition CRACKMAX requires only the drilling of the rock or cement to be able to drain the CRACKMAX and water mixture into the holes. The demolition is completed with utmost safety without the use of protection as in the case of explosives.
CrackMax Expansion Mortar can be used safely, while providing controlled expansive cracking. It can also be used to achieve the perfect slabs and blocks from onyx, marble, granite, or any other type of stone. as non-explosive, soundless and safe demolition agent provides the most technically suitable, environmental friendly and cost-effective alternative solution in dimensional stone application.
Working conditions:
1. Before the blasting, the structure, nature, working environment, engineering quantity, required degree of fracture, and construction period requirements of the building (structure) shall be met. Detailed investigations were carried out on temperature conditions, steel bar specifications and reinforcement conditions. Design the blasting operation, select the crushing agent according to the actual situation, determine the required drilling parameters, drilling distribution and blasting procedures.
2. The blasting of foundations, pile heads, underground facilities or rocks shall be excavated from the surrounding soil layer until the bottom of the blasting is 100 to 200 mm.
3. When dismantling the reinforced concrete, the distribution of the steel bars should be first identified, and then drilled, and the stirrups and part of the vertical bars of the blasting body should be cut with an oxyacetylene flame.
Operating process:
1. The construction procedure of static blasting is: blasting structure (body) investigation → blasting design → selecting crushing agent and drilling parameters → drilling → cutting part of steel bar → filling and pouring → health → secondary crushing → cleaning.
2. The blasthole arrangement depends on the degree of freedom of the structure, or creates as many free surfaces as possible, and adopts different hole-to-hole methods for different free faces. Vertical, horizontal, oblique, etc. can be adopted.
