| Abstract |
The hazards of dry shotcreting equipment and installations and their safety features are dealt with. The chief problem is exposure to cement dust and caustic additives, which cause irritation and a reduction in visibility, with an attendant accident hazard. Methods of wetting the dry mixture are presented. A common cause of accidents is rebounding of mixture particles from the wall: personal protective equipment cannot always be relied on here. Technical solutions to problems of prevention are reviewed, including a remote-controlled system for the spray nozzle. Determination of the initial strength of the concrete is also dealt with. |
