  • Underground excavations
  • Removing boulders
  • Benefits of using Crackamite®

    Crackamite can be used in an almost unlimited range of applications. It’s particularly used for breaking, cutting or demolishing stones, concrete and reinforced concrete. Endless benefits of Crackamite can be listed against explosives and other methods of breaking, cutting or demolishing.

    I. CRACKAMITE® IS A SAFE SUBSTANCE

    Crackamite is not controlled by any legal regulation such as explosives and explosive agents, etc. It is non-explosive, therefore supervision of trained personnel is not essential. Crackamite requires no special precautions if kept in a dry place. The product is not sensitive to electrical discharge or currents. Demolition can be easily and safely performed anywhere.

    II. CRACKAMITE® IS A SOUNDLESS CRACKING AGENT

    Unlike the existing methods of demolition by explosives or breaking equipment, Crackamite does not make any noise, vibration, flying debris, dust or gas. Crackamite quietly and gradually demolishes rock or concrete with its expansive stress caused by hydration reaction. Rocks and reinforced concrete may be demolished safely without environmental pollution. Furthermore, Crackamite's expansive stress continues even after crack initiation, the crack opening distance becomes wider as time passes.

    III. CRACKAMITE® HANDLES EASILY

    No lid (or cap) is necessary after Crackamite is poured into a hole of rock or reinforced concrete, nor is tamping required as with explosives. Crackamite exerts its strength in a short time. Due to Crackamite's strong adhesion and frictional resistance to inner surface of the hole, spurs due to heat-generation (blown-out shot) do not occur when used within the parameters as noted in the conditions. The expansive stress along the hole depth is almost constant except for that near the entrance of the hole. Generally the expansive stress loss from the hole entrance has little effect on the demolition work when hole depth is long.

    IV. CRACKAMITE® IS EASY TO USE - JUST Mix It, Fill It, Crack It

    Just mix with water, pour into holes, then it expands to crack. Neither capping with mortar, sand, etc. nor tamping with a bar is necessary after Crackamite mixed with water is poured into drilled holes in rock or concrete. Using Crackamite does not require a special license unlike explosives, explosive agents, etc. It is environmentally friendly. It releases no toxic or harmful substances of any kind.

    V. CRACKAMITE® HAS AN EXPANSIVE STRESS MORE THAN 11 Mt/m2

    Generally, the compressive fracture stress of rocks is 500 to 2500 T/m2 and that of concrete 300 to 500 T/m2. However, the tensile fracture stress is very small, i.e., it ranges from 40 to 70 T/m2 in concrete, respectively. Since demolition by using Crackamite is based on a fracture due to a tensile stress, all kinds of rocks and concrete can be cracked and broken by using Crackamite when appropriate holes are properly drilled.

    VI. CRACKAMITE® DOES SYSTEMATICAL HIGH-EFFICIENCY DEMOLITION WORK

    Crackamite makes it very easy to control the shape of to-be-cracked objects after being broken according to requirements; it can be demolished or can remain unharmed. Crackamite cracks reinforced concrete, rock, limestone, granite and marble safely and quietly. Being a non-explosive material, it works without noise, vibration, dust, toxic gases and flying rock. Cracked rock or concrete can then easily be broken with breakers remarkably reducing time and cost required for breaking. Crackamite can demolish rock or concrete systematically, and also demolition work in water is possible.

    Crackamite provides the most technically suitable and cost-effective solution in:

    • Restricted demolition of stone and concrete structures where nearby structures must be protected from vibration generated by explosions
    • Pre-splitting of stone formations, to create isolated blocks that can then be more easily demolished
    • Cutting blocks of marble and granite more economically than that of the traditional wire saw method
    • Excavations and demolition of stone or concrete structures where the use of explosives would be expensive due to long operating times, special transport, storage, handling precautions and the need to comply with public safety regulations.

     

    CRACKAMITE. Learn more about Non-Explosive Demolition Agents Non-Explosive Demotion Agents are highly expansive powder compositions for stone breaking, granite and marble quarrying, concrete cutting and demolition. Non-Explosive Demotion Agents are safe, environment friendly and a good and viable alternative to explosives and other traditional methods of quarrying and demolition. CRACKAMITE Non-Explosive Demotion Agents are mixed with clean water and poured into pre-drilled holes on rock and concrete. The diluted CRACKAMITE Non-Explosive Demotion Agent swells and exerts significant expansive thrust on the hole-wall.

    After a certain period, the pressure induced by the Non-Explosive Demotion Agent fractures the wall and splits the rock across the line of the drill holes. Non-Explosive Demotion Agents thus very easily split and fracture mass rock without producing any noise, vibration, toxic gases or flying debris. CRACKAMITE Non-Explosive Demotion Agents are getting increasingly popular in quarrying and demolishing applications. Non-Explosive Demotion Agents can be used in a wide range of applications for safe demolition, concrete cutting, rock breaking and marble & granite quarrying. Non-Explosive Demotion Agents are particularly used for breaking, cutting or demolishing marble, granite and other natural stones, concrete and reinforced concrete.

    CRACKAMITE Non-Explosive Demotion Agents are ideal for use in situations where surrounding buildings or other structures would be damaged by flying debris or vibration.

    CRACKAMITE Crackamite can be used on any type of stone formation, concrete, reinforced concrete or tiled structure in Quarrying and stone cutting, removing boulders, Excavating foundations, Leveling stones for road works, Excavating trenches for pipe-laying, Underground excavations, Demolition of concrete or reinforced concrete objects, Demolition of foundations, Demolition of breakwaters or jetties, Demolition of tiled and refractory structures, and more. Crackamite is a non-toxic powder consisting of calcimined oxides of calcium, silicon and aluminum.

    Crackamite is a soundless, non-explosive and safe demolition agent which is quite different from ordinary demolition agents such as explosives and dangerous materials. It does not cause any fly rock, noise, ground vibration, gas, dust or any other environmental pollution when used properly. Eliminates noise, fly rock and vibration potential caused by blasting or heavy mechanical means. Increases productivity of mechanical demolition equipment. CRACKAMITE Controls cracking.

    Minimizes risk in high exposure situations such as rock or concrete excavation adjacent to hot rail lines or near sensitive fiber optic cables or controls. Works underwater in difficult conditions. Saves time in shutdown conditions. Eases removal where impact force is limited by specifications. Makes removal in confined spaces easier. Accelerates removal time once fracturing occurs. CRACKAMITE Requires no licensing or storage security. Non-Explosive Demolition, Controlled Breaking, Cutting and Cracking. Safe, Easy to use, Cost Effective and Non License Needed.
