PRESSURE BURSTING. This method of demolition can be classified into two categories, mechanical and chemical bursting. Mechanical bursting is done with a hand-held splitting machine that operates on hydraulic pressure provided by a small motor. Although they are more costly, chemicals may be preferred for pressure bursting.

The local zone is instantaneously followed by the bursting zone. In this zone the concrete is subjected to higher tensile stresses, which may cause bursting of concrete mainly along the axis of loading. Generally, special reinforcement is pro-vided in this zone to resist the bursting tensile force caused by these tensile stresses.
