Non Explosive Rock Demolition Agents are commercial products that are an alternative to explosives and gas pressure blasting products in demolition, mining, and quarrying. To use non-explosive demolition agents in demolition or quarrying, holes are to be drilled on the base rock according to drilling pattern supplied. A thoroughly mixed non-explosive demolition agent and water is poured into the drill holes. Over the next few hours the slurry expands, cracking the rock in a pattern somewhat like the cracking that would occur from conventional explosives. Non-explosive demolition agents offer many advantages including that they are silent and do not produce vibration the way a conventional explosive would. In many countries these are available without restriction unlike explosives which are highly regulated. These agents are much safer than explosives, but it is important to follow directions closely in order to avoid steam blow outs during the first few hours after these materials are placed. In natural stone quarrying industry non explosive demolition chemical application termed as ever best method techno-economically because of its unique characteristics of application results. Accurate sizingdimensioning of blocksNo vibration hence No internal cracks & reduction in scrap.Cheapest method compared with other techniques like Wire-Saw Cutting.No supervision required once applied.Less skill and less man power.Multi task execution hence more productivity etc. Now a day in real estate development in urban and sub-urban cities non explosive demolition application become an essential activity due to safety risks in inhabitant areas, And this technology also being used in demolition of concrete structures like Turbine-Generator Foundations in Power Plants, Big size equipment foundations, Gas Pipe Lines Anchor blocks, Pile structures of Bridges, various concrete foundations etc.

The principles applied in using Expansive Mortar are very much similar to those ones followed in traditional blasting techniques. As like for explosives, holes must be drilled to contain Expansive Mortar which must thoroughly be mixed with a measured quantity of water and poured into the holes. Few minutes after filling, a reaction of hydration is taking place generating heat and crystallizing and expanding while hardening. If hydration takes place under confinement, significant expansive pressure will result. Cracks will develop along the line of holes. A person who can deeply understand hydration reaction, Starvation and Expansion process become an expert in this product application. No need for detonator, ignition and certified explosive operators.
