Full Name

ICC-ES AC471 – Acceptance Criteria for Pulverized Glass Pozzolan for Use in Concrete

Scope

ICC-ES AC471 outlines the acceptance criteria for evaluating pulverized glass pozzolan (PGP) used as a supplementary cementitious material in concrete. PGP is a byproduct of glass recycling and can be used to replace a portion of Portland cement in concrete mixtures. The scope of AC471 includes:
  • Material properties: it specifies the chemical and physical requirements for PGP, including its fineness, pozzolanic activity, and chemical composition.
  • Performance requirements: it defines the criteria for evaluating the performance of concrete containing PGP, such as strength, durability, and resistance to alkali-silica reaction (ASR).
  • Testing procedures: it details the standardized testing methods for assessing the properties and performance of PGP and concrete containing PGP.
  • Evaluation and certification: it outlines the process for evaluating and certifying PGP products to ensure they meet the acceptance criteria and can be safely used in concrete construction.
By adhering to ICC-ES AC471, manufacturers can demonstrate that their PGP products meet the necessary performance and quality standards. It also provides valuable guidance to engineers, architects, and builders for incorporating PGP into concrete mixtures for various applications.
