Full Name

ICC-ES AC383 – Acceptance Criteria for Polyolefin Chopped Strands for Use in Concrete

Scope

ICC-ES AC383 establishes the acceptance criteria for evaluating polyolefin chopped strands used as secondary reinforcement in concrete. These strands are added to the concrete mix to improve its properties, such as reducing plastic shrinkage cracking and increasing post-crack toughness.

The scope of AC383 includes:

  • Materials: specifications for the properties of polyolefin chopped strands, including their chemical composition, dimensions, and mechanical properties.
  • Performance: evaluation of the strands’ ability to reduce plastic shrinkage cracking and increase post-crack toughness in concrete, as measured by standardized test methods.
  • Compatibility: assessment of the compatibility of the strands with different types of concrete mixes and admixtures.
  • Durability: evaluation of the strands’ resistance to degradation due to environmental factors, such as UV exposure and freeze-thaw cycles.

By adhering to AC383, manufacturers can ensure that their polyolefin chopped strands meet the necessary standards for performance and durability in concrete applications.
