1.Fed the wet mixture (water, cement and aggregate) into the equipment.
2.Control the air velocity to be used in pushing the wet mixture through the hose to the nozzle.
3.The nozzle should be at least 0.2 meter to 0.5 meter away from the area where the concrete should be applied.
4.The shotcrete operator should be able to use the equipment in a consistent and constant rate with no pulsation to achieve the right compressive strength.
5.To adjust the wet mixture especially when used in a long time, admixtures should be readily available whenever to avoid clogging of the nozzle when the mixtures gets dry.
