Calcium Hydroxide: is a kind of expansive chemical product, which is very popular in the international quarrying and demolishing market.

When it is mixed with clean and cold water to be mortar and poured into pre-drilling holes of rock and concrete, it swells and exerts expansive capabilities on the hole-wall at a unit value of more than 50Mpa (500kg/cm2 .) which is strong enough to cut and crack reinforced concrete, marble and granite after a while.

Copmare to the traditional explosives, it has the following advantages:

1)Non-explosive and very safe

2)very economical and cost-effective;

3)The shape is controllable

CRACKAG can be applied to various situations:

  1. Granite, marble, sandstone, limestone, quartzite quarrying and cutting

  2. Precious stone quarrying

  3. Rocks pre-splitting, fracture, cutting, demolishing and removal

  4. Concrete structures demolition and rocks cracking when explosion not allowed

  5. Fracture and demolition of the concrete buildings and structures

  6. Rocks cutting for road construction.
