Cast tops and bottoms or other electrolytic cells concrete sections using power tools.
Feed the concrete mixer with cement, sand, water, rock or other required materials using the shovel, making sure the specifications are met.
Maintain, repair and clean moulds and mould parts, e.g. by smoothening out imperfections on the surface. Use water, grease or oil to wash and scrape the moulds by hand.
Measure and mix ingredients for casting and moulding materials, according to appropriate formula.
Prevent the casting sticking to the moulds by brushing the mould with oil, hot wax or graphite solution, according to the specification of each casting components.
Open mould and safely remove the finished cast from within.
Settle the concrete using the vibrating tables.
Dump the batches into conveyors making sure the specifications such as the mixing time are followed.
Oversee uniformity of moulds. Use casting equipment and tools such as hand press.
Use compact concrete mixers or various ad-hoc containers such as wheelbarrows to mix concrete. Prepare the correct quantities of cement, water, aggregate and optional added ingredients, and mix the ingredients until an homogenous concrete is formed.

Perform the cleaning of mixers in order to prepare them for mixing different types of compounds.
Operate or tend furnaces, such as gas, oil, coal, electric-arc or electric induction, open-hearth, or oxygen furnaces, to melt and refine metal before casting, to produce specified types of steel, or to finish other materials such as cokes. Set furnace controls to regulate temperatures and heating time.
Ability to load and unload pallets on vehicles in a safe way.
Transfer bricks from the dry-press to the kiln car, stacking them according to specifications.
Adjust the temperature of the curing ovens by turning dials so that it is set to the correct parameters.
Maintain records of the progress of the work including time, defects, malfunctions, etc.
Regularly inspect and perform all required activities to maintain the equipment in functional order prior or after its use.
