Concrete Demolition Principle

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.
