What is one of the duties of a shotcrete pump operator?

The function of a shotcrete pump operator includes several key responsibilities to ensure the successful application of shotcrete. Among these duties, monitoring the water content is particularly vital. The water content directly influences the consistency and workability of the shotcrete mixture, impacting its strength and durability once it sets. By ensuring the correct proportion of water is used, the operator helps maintain the right flowability and adhesion of the mix, which is crucial for effective application and performance of the shotcrete in various constructions, such as pool walls or other structures.

While other responsibilities like mixing the shotcrete, controlling the pressure, or cleaning the equipment are also important, they fall under different aspects of the shotcrete process or other roles. The mixing typically refers to the initial preparation stage, while pressure control is about managing how the mixture is applied. Cleaning the equipment is necessary for maintenance but does not directly affect the quality of the shotcrete application in the same immediate way as monitoring water content does.
