What must be done to the protective sleeve holding polystyrene aggregate?

1. It should be replaced regularly

2. It must not be cut

3. It should be painted for visibility

4. It must be lined with additional material

The correct answer is: It must not be cut

The protective sleeve holding polystyrene aggregate must not be cut because doing so could compromise its integrity and effectiveness. The purpose of the protective sleeve is to contain the aggregate and prevent it from being exposed to the elements, ensuring that it maintains its insulating properties and structural integrity. Cutting the sleeve can lead to the loss of aggregate material, potential contamination, or degradation of performance due to environmental exposure. In contrast, while replacing the sleeve regularly or painting it for visibility may seem beneficial for maintenance or identification, they do not address the fundamental importance of keeping the sleeve intact. Lining it with additional material might provide extra protection but isn’t a requirement and could introduce complexities that may not be necessary. Ensuring that the sleeve remains uncut is crucial for the longevity and effectiveness of the polystyrene aggregate it contains.
