WHAT IS EXPANSIVE MORTAR/ CRACKING POWDER/ DEMOLITION AGENT?

Non-Explosive Demolition Agent is a non-toxic and cementations powder, which consisting of calcined oxides of calcium, silicon and aluminum, EXPANSIVE MORTAR becomes a highly powered amazing expansive pressure of T / m2 when mixed with water. Marble, granite, limestone, plain concrete, reinforced concrete, boulders, and ledge are fractured overnight without noise, vibration, or fly rock. Especially, used as environment constraints or when explosive is not permitted for use.


HOW DOES DEMOLITION AGENT/ EXPANSIVE MORTAR WORKS?


It develop rise of highly expansive capabilities at the consistent volume exceeding 122 Mpa ( T/ M2) more than enough to break up any materials to be cut or demolished. The tensile strength for most rock is less than 5-25 Mpa (500- T/m2 50-250 kg /cm 2), Reinforced concrete breaks at 3-5 Mp (30-50 kg /cm2, 300- 500 T/ M2).

Features of Crackamite

Crackamite mixed with an appropriate quantity of water and poured into cylindrical holes drilled in rock or concrete, creates an tremendous expansive pressure of 11 MT/m², cracking the substrate to be demolished or split.

• It is a non-toxic powder made of oxides of calcium, silicon and aluminium.
• It causes no explosion, noise, vibration, gas, dust or any other pollution
• It develops tremendous expansive pressure within a few hours of pouring
• It is easy to use and has no special requirements or licensing
• It provides highly targeted splitting and demolition
• It is suitable for all kinds of rocks, stones, boulders and concrete.

Advantages of Crackamite

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

i. Crackamite is a safe substance

Crackamite is not controlled by any legal regulation as is the case in explosives and other explosive agents, etc. It is non-explosive, therefore, supervision of trained personnel is not essential. Crackamite has no special storage requirements or precautions if kept in a dry place. Crackamite is not sensitive to electrical discharge or currents. Demolition can be easily and safely performed anywhere, outdoors or indoors and even underwater.

ii. Crackamite is a soundless cracking agent

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

iii. Crackamite is easy to handle

No lid or cap is necessary after Crackamite is poured into a hole of rock or reinforced concrete, nor is any 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 limit parameters. The expansive stress along the hole depth is almost constant except 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 very easy to use

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

v. Crackamite creates tremendous expansive stress

Generally, the compressive fracture stress of rocks is 500 to T/m² and that of concrete 300 to 500 T/m². However, the tensile fracture stress is very small, it ranges from 40 to 70 T/m² in concrete. 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 is high-efficiency and systematic

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 and removed
• Cutting blocks of marble, stone 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.

Comparison Of Demolition Methods

There are many superior points in the demolition work performed by Crackamite as compared to other demolition methods. It has also been proven to be more economical. The outline of this comparison indicated in the table1 below:
