Factors Affecting The Expansive Stress / Pressure Of Crackamite®

  1. The expansive stress can be increased to more than 11,200 T/m2. (Fig. 1 & 3)
  2. The larger the hole diameter is, the greater the expansive stress becomes. (Fig. 2)
  3. There is little change in the expansive stress when the water ratio is in the neighborhood of approximately 30 %. However, the stress is decreased as the water ratio is increased or decreased.

Fig. 3 Changes in the expansive stress of CM - A

a. The expansive stress developed by Crackamite reach a maximum value at about 24 hours of reaction. However it still keeps increasing slightly even afterwards.
b. The expansive pressure of Crackamite decreases as the water to Crackamite powder ratio increases. The optimum ratio is 0.30.
c. The expansive capabilities of Crackamite increases with increase in ambient operating temperature upto the maximum operating temperature.
d. The expansive power of Crackamite decreases with increase in the diameter of pre-drilled hole above the optimal value.

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.

Cracking Design Reference Chart.

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.
