Expansion rock cracking agent (also known as silent breaking agent, static breaking agent, rock breaking agent, etc.) is a kind of powdery engineering construction material that can break rocks and concrete without use. Its main component is quicklime (i.e. calcium oxide), and it also contains some compound catalysts mixed in a certain proportion. The principle of breaking media is to use the static breaking agent installed in the media borehole to produce hydration reaction after adding water, so that the crystal of the breaking agent will be deformed, resulting in volume expansion, so that the expansion pressure (up to 30Mpa~50Mpa) will be slowly and quietly applied to the wall, and after a period of time, the value will be reached, and the media will be broken. It can be widely used in the silent crushing and demolition of concrete structures and rock mining, solving the problem that crushing is not allowed but must be broken in the construction of crushing works. The construction process of crushing is also very simple: for the crushed medium, after reasonable crushing design (determination of aperture, spacing, etc.) and drilling, The powdery crushing agent is mixed with proper amount of water to form a flowing slurry and directly injected into the borehole. After half an hour or several hours (mainly determined by the water cement ratio), the medium (rock - tensile strength is 5~10Mpa or concrete - tensile strength is 2~6Mpa) will self expand and break. The characteristics of expansive rock cracking agent are: (1) safe and easy to manage. Static crushing agent is non dangerous. No special type of work such as crushing is required during operation. Crushing agent can be purchased, transported and used just like other ordinary goods. (2) Environmentally friendly materials. Silent, vibration free, flying stone free, gas free and dust free in use, it is an internationally popular pollution-free environmental protection product. (3) According to the crushing requirements, design appropriate hole diameter, hole spacing and angle to achieve the desired effect.
