Motivation

fib Commission 8 (COM8) aims to identify concrete-related durability issues, consider and review current information available on the topic, and provide guidance on materials and methods that will assist in optimal durability design of new structures and restoration design of existing structures.

Scope and objective of technical work

Service life design forms one part of this and COM8 will develop rational procedures to obtain an optimal technical-economic performance of concrete structures in service and to ensure that sustainability, whole-life cost and associated through-life perspectives are taken into account as part of the process by which experience gained from practice is fed back to the design, execution, maintenance and rehabilitation stages. COM8 work will address the structural service life aspects of structures with rational strategies, procedures and criteria for design, assessment, maintenance and remediation.

COM8 work also includes review of methods for the determination of inspection frequencies as well as methods based on sound engineering principles that will provide optimal information for the durability assessment of marine structures.

  • TG8.1 - Model technical specification for repairs and interventions

    Task Group 8.1 is preparing a 'Compendium on Protection, Repair and Strengthening of Concrete Structures'. This aims to be a repository of large scope knowledge on the topic ‘rehabilitation’, containing short and specific (inspection, design, detailing, and execution) guidelines, listing reference documents (codes, technical reports, scientific papers) and presenting illustrative case studies on each subject.

    A first draft of the compendium is almost ready to be reviewed by Commission 8 members, as well as by TG3.4 members. It is envisaged to be published as a technical report or a guide to good practice, depending on the commissions’ recommendations. The document includes three parts, organized in protection, repair and strengthening techniques. A template for methods’ guidelines, as well as a template for case-studies, has been delivered to authors to reach a harmonized presentation of each chapter.

  • TG8.8 - Design approaches

    Throughout durability design there are a number of common inputs that should be handled in a consistent approach, e.g. reliability, cracking, exposure risk assessment, verification approaches.

    This Task Group will maintain approaches that are consistent across different materials and durability design approaches consistency and provide liaison with other Commissions to ensure consistency across all aspects of Model Code.

    The scope:

    • This Task Group shall investigate various aspects that have a common impact on modelling of deterioration mechanisms but the TG is not directly involved in the mechanisms or materials.
    • Many of these items are fundamental to all aspects of structural design and cannot be considered durability issues alone. However, the issues are key to durability design.

    The work in TG8.8 is currently carried out in the following Working Groups:

    • TG8.8 WG1 - Durability Planning – Convener: Rodney Paull
    • TG8.8 WG2 - ULS verification under chloride- and carbonation-induced deterioration – Convener: Robby Caspeele
    • TG8.8 WG3 - Exposure Zones – Convener: Joanitta Ndawula
    • TG8.8 WG4 - Eco-efficient concretes and clinker efficient binders – Convener: Stefanie Von Greve-Dierfeld

  • TG8.9 - Deterioration Mechanisms Related to Corrosion

    TG8.9 will investigate models for the following deterioration processes: Rebar Corrosion Initiation; Rebar Corrosion Propagation; Abrasion, Erosion and Cavitation; Freeze Thaw Attack; Leaching; Water and Water Vapour Migration and Chemical Attack.

    In MC2010 and Bulletin 34, some of these mechanisms have only loosely defined models and some have no models. MC2010 also has limited advice for exposure classes, performance tests, deemed to satisfy requirements and avoidance approaches.

    Scope:

    • This Task Group shall investigate prediction tools (models)
    • Derive revised design rules, which ensure sufficient durability close to broadly accepted reliability levels of limit states identified in TG8.8 and to be considered in TG8.9 and TG3.4
    • The TG will provide specific input into MC2020 but is expected to continue as a COM8 TG to continuously develop the solutions for the issues listed.

    The work in TG8.9 is currently carried out in the following Working Groups:

    • TG8.9 WG1 - Corrosion Initiation – Convener: Amir Rahimi
    • TG8.9 WG2 - Corrosion Propagation – Convener: Carmen Andrade
    • TG8.9 WG3 - Chloride threshold – Conveners: Frank Papworth, Federica Lollini

  • TG8.11 - Testing and Monitoring

    Durability design of concrete structures may incorporate a number of performance-based requirements depending on the deterioration mechanisms and exposure conditions to consider. While exposure definitions and performance-based requirements are dealt with in other fib TG’s, well documented test procedures for relevant materials properties are needed for support of the durability design and subsequent quality assurance. This includes well-founded probabilistic definitions for those properties.

    The objective of Task Group 8.11 is to provide guidance on test methods and corresponding acceptance criteria and testing frequencies concerning quality assurance of concrete production. Furthermore, the objective is to link performance-requirements of concrete as yielded from durability design with the execution. For the latter, all stages of concrete production, i.e. pre-testing in the laboratory, trial testing in laboratory and on-site, and testing of running production are considered.

    The work in TG8.11 is currently carried out in the following Working Groups:

    • TG8.11 WG1 - Testing New Concrete – Convener: Carola Edvardsen
    • TG8.11 WG2 - Testing Old Concreten – Convener: Roberto Torrent
    • TG8.11 WG3 - Monitoring of Concrete – Convener: Joan Casas Rius
