ACI 506.6T-17 PDF Download

The ACI 506.6T-17 standard outlines the importance of visually examining shotcrete cores for assessing the quality of shotcrete during construction. This standard is aimed at various stakeholders including owners, architects, engineers, and contractors who are involved in shotcrete projects.

Shotcrete cores are typically extracted from sample panels or as-placed shotcrete for evaluation purposes. In addition to the routine tests such as compressive strength or other material quality tests required by project specifications, visual examination of these shotcrete cores by an experienced licensed design professional (LDP) is emphasized as a crucial tool for evaluating the quality of shotcrete.

By visually inspecting the shotcrete cores, the LDP can identify any potential defects, irregularities, or inconsistencies in the shotcrete, which may not be evident through other testing methods. This visual examination is an essential complement to the standard material quality tests and helps ensure that the shotcrete meets the desired standards and specifications.
