Full Name

ICC-ES AC217 – Acceptance Criteria for Concrete with Virgin Cellulose Fibers

Scope

ICC-ES AC217 outlines the requirements for evaluating concrete mixtures that incorporate virgin cellulose fibers as an admixture. These fibers are added to improve the concrete’s properties, such as reducing plastic shrinkage cracking and enhancing durability. The scope of AC217 includes:
  • Material properties: it specifies the requirements for the virgin cellulose fibers, including their source, composition, fiber length, and other physical properties. It also addresses the requirements for the concrete mix design, including cement type, aggregate properties, and water-cement ratio.
  • Performance requirements: it defines the criteria for evaluating the performance of concrete with virgin cellulose fibers, including its resistance to plastic shrinkage cracking, flexural toughness, and impact resistance.
  • Testing procedures: it details the standardized testing methods for assessing the properties and performance of concrete containing virgin cellulose fibers.
  • Evaluation and certification: it outlines the process for evaluating and certifying concrete mixtures with virgin cellulose fibers to ensure they meet the acceptance criteria and can be used in construction applications.
ICC-ES AC217 is crucial for manufacturers to demonstrate that their concrete mixtures with virgin cellulose fibers meet the required performance standards. It also provides valuable information to engineers, architects, and builders for selecting and using suitable concrete mixtures with enhanced properties for various applications.
