    1. Rationale

    Standardized labeling on containers of single-use concrete cylinder molds will clarify their intended use and provide traceability as a part of acceptance testing. Single-use molds can become distorted if stored with their axis in the horizontal position for extended periods. Directional arrows on the containers will provide information for proper orientation in handling and storage, minimizing deformation.
