High Range Soundless Cracking Agent Demolition of building concrete or stone
For building concrete or stone that is not suitable for blasting demolition, our High Range Soundless cracking agent is a good choice.
With the continuous development of economic construction, urban controlled blasting technology has played an increasingly important role in urban construction and transformation. However, the impact of vibration, impact, flying stones, etc. caused by controlled blasting on the surrounding area has not been completely eliminated. The demolition of some old buildings in the urban area is not allowed to use blasting due to the restrictions of blasting safety. Even if controlled blasting is allowed, it will also bring great difficulties to blasting due to various conditions. Our High Range Soundless Cracking Agent is particularly suitable.
High Range Soundless Cracking Agent (also known as Expansive Mortar, Stone breaking chemical, etc.) is a powdered construction material that can crack rocks and concrete without using explosives. Its main component is quicklime (i.e. calcium oxide), and it also contains some compound catalysts mixed in a certain proportion. The principle of the crushing medium is to use the static crushing agent installed in the medium borehole to react with water to cause the crushing agent crystal to deform and expand in volume, so as to slowly and quietly apply the expansion pressure (up to 30Mpa-80Mpa) to the hole wall, and reach the maximum value after a period of time, breaking the medium. It can be widely used in the silent crushing and demolition of concrete structures and rock mining, solving the problem of concrete or rock crushing in blasting engineering construction where explosives are not allowed to be used. It is a new, environmentally friendly, non-explosive construction material popular internationally. The crushing construction process is also very simple: for the crushed medium, after reasonable crushing design (determination of hole diameter, hole spacing, etc.) and drilling, the powdered crushing agent is adjusted to a flowing slurry with an appropriate amount of water and directly injected into the borehole. After several hours (mainly determined by the water-cement ratio), the medium (rock-tensile strength of 5-10Mpa or concrete-tensile strength of 2-6Mpa) will expand and break by itself. Silent expansive agent is a new method of crushing or cutting rock and concrete developed in recent years, also known as static fracturing or static crushing technology.
