ACI 222.2R-14 PDF Download

The ACI 222.2R-14 standard provides comprehensive information on various types of prestressing steel and their corrosion mechanisms. The report serves as a supplement to the ACI 222R standard and focuses specifically on topics related to prestressing steels.

The standard discusses different types of prestressing steel, including their metallurgical differences. It also delves into deterioration mechanisms, such as hydrogen embrittlement and stress-corrosion cracking, which are specific to prestressing steel. The report explains these mechanisms and provides insights into how they can be prevented or mitigated.

In terms of protecting prestressing steel against corrosion in new construction, the standard presents various methods and techniques. It includes discussions on the field performance of prestressed concrete structures, shedding light on the real-world challenges and experiences related to corrosion in these structures.

Additionally, the standard provides valuable information on field evaluation and remediation techniques for prestressed concrete structures. This section of the report offers practical guidance on assessing the condition of structures and implementing necessary repairs or corrosion prevention measures.

Appendixes in the standard provide more detailed information on stress corrosion cracking, hydrogen embrittlement, and related issues in prestressed concrete. These appendixes offer insights into the specific challenges associated with corrosion in prestressed concrete structures and present mitigation techniques.
