ICC-ES AC459

Full Name

ICC-ES AC459 – Acceptance Criteria for Proprietary Hydraulic Cement

Scope

ICC-ES AC459 establishes the requirements for evaluating proprietary hydraulic cement. These are cements with unique formulations or properties that differ from standard cement types defined in ASTM C150 or AASHTO M85. The scope of AC459 includes:
  • Material properties: it specifies the requirements for the physical and chemical properties of proprietary hydraulic cement, such as fineness, setting time, soundness, compressive strength, and chemical composition.
  • Testing procedures: it outlines the standardized test methods for evaluating the properties of proprietary hydraulic cement, ensuring consistency and reliability in the assessment.
  • Evaluation and certification: it provides a framework for evaluating proprietary hydraulic cement to determine if it meets the acceptance criteria and can be safely used in construction.
ICC-ES AC459 is crucial for manufacturers who develop and produce proprietary hydraulic cement. By adhering to this acceptance criteria, they can demonstrate the quality and performance of their products, ensuring their suitability for various construction applications.
