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