Application
This unit describes the skills and knowledge required to prepare for and apply shotcrete refractory installation. Shotcrete is the generic term used to describe the placement of cementitious products, including concrete or refractory monolithics, by high volume and high velocity air. It is also known as guniting.
This unit applies to installation with shotcrete alone and with shotcrete that needs to join to brick, block, moulded or cast refractory. The refractory may be applied by wet or dry processes.
This unit applies to operators who are required to take responsibility for own outputs and follow established procedures to prepare for and apply shotcreting to procedures and specifications; mix the shotcrete and correct any deficiencies in the quality of work. Operators are also required to work autonomously and apply their own judgement to interpret information; monitor processes; identify and address routine and non-routine problems and hazards.
This unit applies to an individual working alone or as part of a team or group and in liaison with other shift team members, team leader and supervisor.
No licensing or certification requirements exist at the time of publication. Relevant legislation, industry standards and codes of practice within Australia must be applied.
