What is a potential consequence of using aggregate larger than the specified size?

Using aggregate larger than the specified size can lead to invalid test results due to several factors affecting the properties of the concrete mix. The specified aggregate size is designed to ensure the appropriate workability, strength, and bonding characteristics of the concrete. When larger aggregates are used, they can create issues such as poor compaction, increased difficulty in achieving a uniform mix, and potential segregation of materials.

These factors can result in inconsistent performance of the concrete, impacting its durability, strength, and overall quality. Consequently, if test results are based on a mix that does not comply with the specified aggregate size, the data generated from those tests may not accurately reflect the material's intended performance, making the results unreliable for future applications or structural integrity assessments.
