Mixing of Crackamite®

CRACKAMITE is a powder that must be thoroughly mixed with clean water before use, in a ratio of 30 % of the overall weight (1.5 liters for each 5 kg package). Gradually add the powder to water, stirring all the time to obtain a smooth, lump-free mortar.

I. Mixing Equipment:

Mix Crackamite with water, one bag at a time, by hand or, preferably, with a mechanical mixer. Prepare the following equipment.

(1) Container: A metal bucket or clean can of 10 - 20 liters capacity.

(2) Mixer: For example, a hand-mixer.

(3) Water measure: Beaker or measuring cylinder.

(4) Protection: Rubber gloves, safety glasses.

II. Mixing Method:

Pour approximately 1.5 liter (0.4 U.S. gallon) of water into container. Add one bag of Crackamite gradually and mix well until it has a good fluidity.

When viscosity of the mixture of Crackamite and water is too high to pour into the hole, add a little water to get a good fluidity. Do not exceed 34% of water ratio (1.7 liter; 0.45 U.S. gallon per 5 kg; 11 lb. of Crackamite). The mixing time by hand-mixer is about 2 - 3 minutes. It is recommended that a mechanical mixer be used on large volume jobs. When mixing by hands, wear rubber gloves.

III . Mixing Water:

  1. Use clean water that is not contaminated with oil, organic substances, etc.
  2. Use the proper temperature of water for each grade of Crackamite (refer to Table 1)
  3. Water at a temperature below 15°C (59°F) must be used when the average atmospheric temperature is more than 45°C for Crackamite CM - H.
  4. The cooler the water is, the longer Crackamite will remain fluid.

IV. Standard Quantity:

The quantity of Crackamite to be used for cracking differs with the hole spaces and diameters. In Table 2, the relation between the quantity of Crackamite used and the hole diameters is indicated for the hole of 1 m depth, where Crackamite is mixed at a water ratio of 30%.

Table 2 - Kg/m values for different hole sizes
Hole Diameter 30 mm 36 mm 40 mm 46 mm 50 mm
Crackamite (Kg/m) 1.2 1.7 2.1 2.8 3.2
Hole Depth One Meter
Note: You may get 3% to 6% less due to field conditions.

V. AUDIT CHECKLIST BEFORE MIXING

  • Are people on the work site wearing safety glasses?
  • What is rock/concrete temperature?
  • What is water temperature?
  • What is drill hole diameter?
  • Have you calculated the extra water required if rock/concrete temperature is above 22°C?
  • Are you going to cover the filled holes with a tarpaulin sheet?
  • How much time does it take to fill the hole?

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.
