Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Sprayed Concrete Mobile App
Sprayed concrete—known as shotcrete—uses high-powered hydraulic, pneumatic or electric plant to apply concrete by projecting it through the air.
How does it work?
Shotcrete application should only be carried out by a competent person. Shotcrete mixture should be designed to meet the strength and workability specified and to minimise dust levels. A wet mix shotcrete should be used along with non-caustic accelerators. Surfaces contaminated with oil, dust or mud should be cleaned before shotcrete application and water entry is diverted. During shotcreting no other activities should be carried out. Control measures should be implemented to eliminate or minimise, so far as is reasonably practicable, the risks associated with sprayed concrete. The Guide Tunnelling (Australia): Specific Hazards, Risks and Control Measures – Sprayed Concrete mobile app includes specific hazards, risks and control measures - sprayed concrete.
