Why is the documentation of aggregate gradation important?

The documentation of aggregate gradation is essential because it ensures compliance with specifications. Aggregate gradation refers to the size distribution of the aggregate particles used in concrete mix design. Adhering to specified gradation limits is crucial because it affects the concrete's workability, strength, durability, and overall performance.

By accurately documenting the gradation, inspectors can verify that the aggregates meet the required standards set by engineering specifications. This compliance is critical for maintaining the integrity of the construction project, as non-compliant materials can lead to structural failures, poor performance, or increased maintenance costs in the future. Comprehensive documentation acts as a safeguard, ensuring that the materials used in the mix conform to the design requirements and industry standards, which is a fundamental aspect of quality control in construction practices.
