Final surface cleaning— Use abrasive blasting (Fig. 4) to remove residual dust, debris, fractured concrete, and contaminants that prevent proper bonding. If abrasive blasting is not feasible, pressure washing usi ng a minimum 3000 psi (250 MPa) may be acceptable depending on .
Evaluating and Managing Blasting Risk Page 1 EVALUATING AND MANAGING CONSTRUCTION BLASTING RISK By G. F. Revey1 ABSTRACT: While representing owners at projects where explosives are used to excavate rock or demolish concrete, engineers participate in the management of blasting risk when they a) design projects, b) develop
Abrasive blast cleaning generally is considered to be an economical process. It is faster th~n competitive processes of pickling, electrochemical cleaning, or hand finishing, and thus reduces manhours required. In addition, equipment investment is not sUbstantially influenced by model changes, operational procedures,
Abrasive blasting is more commonly known as sandblasting since silica sand has been a commonly used material as the abrasive, although not the only one always used. Abrasive blasting entails accelerating a grit of sand sized particles with compressed air to provide a stream of high velocity particles used to clean metal objects such as steel ...

surfaces such as steel, bricks, cement and concrete. The most common method uses compressed air to propel abrasive material from a blast pot, through a blasting hose to a nozzle that is manually controlled by the operator. Automated abrasive blasting machines such as centrifugal wheel systems and tumblers are also used. Blasting is generally
