What is one of the functions of the setting process in concrete work?

The setting process in concrete work is essential for achieving a strong and durable final product. One of its key functions is to eliminate air bubbles, which can compromise the integrity of the concrete. During the setting phase, it is crucial for the concrete mixture to be properly consolidated, as trapped air bubbles can weaken the structure and lead to issues like reduced durability or failure under load.

The setting process facilitates the development of the concrete's hardness and strength as it undergoes hydration, allowing for more uniform and dense material. This helps ensure that the final concrete mix has the desired mechanical properties necessary for its intended application.

The other options do not align with the primary functions of the setting process in concrete work. Increasing drying time would typically be an undesirable outcome, while keeping blades and chains cool relates more to equipment operation than the concrete itself. Speeding up evaporation could actually lead to problems such as surface cracking or insufficient hydration, which the setting process aims to mitigate by allowing the correct conditions for curing.
