What should happen if cement or fly ash arrives at the plant without the proper seals?

If cement or fly ash arrives at the plant without the proper seals, it must not be accepted. Proper seals are crucial as they ensure the materials meet specifications and have not been compromised during transit or storage. Accepting materials without the required seals could lead to significant quality control issues, potentially affecting the strength, durability, and overall performance of the concrete produced. The absence of seals indicates a lack of assurance that the materials have been protected from contamination or degradation, which would be against industry standards. Therefore, to maintain the integrity of the concrete production process and comply with safety and quality regulations, such materials should be rejected outright.
