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 Working Groups below.
-
WP8.8.1 - Durability planningDuring the MC2020 work it was proposed to give a complete overview of all activities related to durability planning of a project. Presentations on formal durability planning were given by Rodney Paull to TG10.1 and COM8. This resulted in current draft section 27.6 (minor comments in 35.6 and 38.1.2) in draft MC2020. An initiative has been taken to work out supporting materials to MC2020 on these matters.The WP will start its work in autumn 2022 and depends on the content development in MC2020.

WP8.8.2 - ULS verification under chloride- and carbonation-induced deteriorationThe reinforcement corrosion process is traditionally divided into two time periods: the initiation period and the propagation period. With respect to the former, generally accepted models are available in e.g. the fib Bulletin 34 and MC2010, while for the latter no generally accepted model is available. Different types of models for the propagation phase have been proposed in literature, e.g. based on empirical data or based on the resistivity of concrete, but these are not yet fully incorporated in the assessment of existing structures, and there is a lack of the consistent treatment of the associated uncertainties. Reinforcement corrosion causes a number of interacting damage modes, which have an impact on the corrosion progress itself and on the component’s structural behaviour: overall/local reduction of the rebar’s effective cross-section, expansive nature of the corrosion product causing internal stresses, concrete cracking and spalling, degradation of the bond and reduction of ductility of the reinforcement steel.The developments in this working group focusses both on new structures (i.e. when relating to the quantitative estimation of time-dependent behavior accounting for the propagation phase, taking avoidance measures for durability problems, assessing the need for redundancy, etc.) and on the assessment/rehabilion of existing structures (i.e. performing time-dependent ULS and SLS verification for the remaining or desired extended service life in case chloride- and carbonation-induced corrosion materialized).

WP8.8.3 - Exposure ZonesThe original aim of fib TG WP was to critically review existing global standards and recommendations for exposure categories for concrete structures, highlight shortcomings in the existing approaches and, where required, propose updated exposure categories for inclusion in MC2020. This has been completed in 2021.The WP has developed an updated table of exposure classes for inclusion in MC2020. A supporting paper was published in Structural Concrete in March 2021. WP3 intends to expand the supporting paper into a Bulletin.

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
