Motivation

The overall motivation of fib Commission 4 (COM4) is to make theoretical and practical developments in the field of concrete and concrete technology, and to present these developments in an understandable and code-type formulated manner. COM4 positions itself at the forefront of new technologies and techniques by considering both fundamental research and practical issues.

Scope and objective of technical work

The aim of COM4 is to collect and to validate information on the properties and behaviour of concrete for structural applications subjected to various types of loading and environmental conditions. The commission focuses its attention both on traditional types of concrete, in particular under unusual conditions, and on new types of concrete and cementitious composites under all types of loading and condition. The properties of the concrete types considered should be formulated in such a way that it is possible to derive behavioural models and design recommendations for practical applications.

  • TG4.0 - Code-type Concrete Models

    The first target of TG4.0 consists in developing an updated code-type presentation of the constitutive and durability related behaviour of structural concrete for inclusion in MC2020. The basis and point of origin of the AG’s/TG’s work is formed by the existing chapter 5.1 “Concrete” in MC2010. The work of TG4.0 comprises firstly a critical review and an updating of the existing models, further the implementation of new available concrete models, taking into consideration the increase of knowledge by research within the last decade. Major criteria for models being suited are their physical and thermo-dynamical soundness and accuracy as well as practical characteristics like simplicity and operationality. Further, emphasis is placed on concise explanatory notes and well-selected references which will be given as commentary (left-hand column) to the code text.

    The second target of TG4.0 consists in preparing a background document (Bulletin) on the concrete models included in the chapter “Concretes” of MC2020. This document will give detailed background information together with the results of analyses and evaluations. Thus, the bulletin will represent a comprehensive summary of the relevant knowledge available to the members of the Task Group 4.0 at the time of its drafting. Moreover, the new bulletin will provide an essential basis for the development of future generations of code-type models related to the characteristics and the behaviour of structural concrete. Further it will offer insights into the complexity of the normative work related to code-type concrete modelling, leading to a better understanding and adequate appreciation of MC2020.

    This new Bulletin will be an update of the Bulletin 70 “Code-type models for concrete behaviour – Background of MC2010”, which has been released parallel to MC2010 in 2013.

  • TG4.1 - Fibre-reinforced concrete

    Model Code 2020 has completed the draft related to the homogenization of FRC to RC and PC design rules,starting from the principles introduced for the first time in Model Code 2010.

    Even if the proposed equations are now better harmonized with those controlling the behaviour of the common concrete structures, many aspects, remained out of the code.

    These aspects have been already investigated mainly in relation to steel fibres, but we need to extend them to any type of fibres and to hybrid concretes. Moreover, the market has been strongly oriented to sustainability and to the introduction of new matrixes to reduce CO2 emissions and therefore we have to understand which effectiveness can be guaranteed with the adoption of these eco-mixes.

    After the publication of the Bulletin 105, we need a special bulletin able to propose other examples of real applications, aimed at checking the effectiveness of the equations introduced and the advantages correlated to sustainability. These examples should be also analysed in other Commissions like the number 1, 3 and 7. When a good proposal concerning the indicated aspects will be achieved, the suggestion is to introduce it, updating the actual draft of Model Code, without waiting for the next edition. To this aim a special role should be played by databases: the database already started by Albert De La Fuente has to be developed, because it could help the evolution of future proposals, making them much more reliable. It has to be enlarged to UHPC where a special need of data is required.

  • TG4.3 - Structural design with flowable concrete

    Flowable concrete (highly flowable, self-compacting and/or self-levelling) has evolved from a special type to a commonly applied building material. fib Task Group 4.3 (TG4.3) considers three aspects of flowable concrete (FC) for structural design: material properties, production effects and structural boundary conditions. The flow of concrete (initiated by some vibration and/or the weight of concrete) can affect the structural characteristics of hardening or hardened concrete. The mixture composition has to be adjusted and optimised in order to obtain a high flowability. TG4.3 aims at promoting the application of flowable concrete, improving and adapting the concrete design and the production technology and its implementation in guidelines and codes.

  • TG4.4 - Restoration of heritage in exposed concrete

    The activity of Task Group 4.4 is focused in aesthetics of concrete surfaces. The topic is relevant for all exposed concrete structures but holds particular importance in the case of buildings designed by well-known architects. Previous work by this Task Group addressed the issues that need to be considered regarding concrete mix design and casting, aiming at obtaining exposed concrete surfaces with homogenous appearance. A state-of-the-art technical report was prepared with recommendations and guidelines.

    Since existing exposed concrete structures are in direct contact with the environment, they are prone to experience degradation faster, and since appearance is a main key-issue, maintenance of this type of structures needs to be properly addressed. In addition, many of these structures have a unique cultural (historical, architectural, technical, other) value, being therefore classified as heritage. For this reason, the repair techniques adopted for current concrete structures may not be adequate in some situations and restoration methods must be adopted instead.

    TG 4.4 future work will address the issues that need to be considered regarding conservation and restoration of the built heritage in exposed concrete. The main goal of the Task Group is to publish an fib guide of good practice, including recommendations and guidelines, as well as successful examples that can be assumed as reference case studies.

  • TG4.5 - Time-dependent Behavior of Concrete

    The primary objective of the task group is to identify limiting aspects during the design of new or assessment of existing structures related to predicting the time-dependent (mechanical) behavior of “new” but also “traditional” concrete types. Based on the identified short-comings the task group will initiate literature reviews, compile/ update consistent databases and update existing model formulations. Where possible the TG will make use of the data already available in the scientific literature. Where this is not the case, the task group will strive to develop research strategies and coordinate research efforts by its members, supported by national or international research funds.

    The task group plans to develop databases and calibrated prediction models for the time-dependent mechanical properties of cast concrete including:

    • Maturity vs. time concepts, applicable to early age and multi-decade predictions
    • Development of compressive and tensile strength as function of maturity/ time;
    • Development of Young’s modulus as function of maturity/ time;
    • Development of fracture energy as function of maturity/ time;
    • Development of creep and shrinkage as function of maturity/ time;
    • Empirical relationship between mechanical properties and compressive strength as function of maturity/ time;
    • Development of stress-strain diagram as function of maturity/ time;
    • Transport of liquids and gases;
    • Guidance for the coupled hygro-thermal chemo-mechanical analysis of concrete with relevance to e.g. mass concrete or certain structural components prone to early-age cracking;
    • Guidance for the time-dependent nonlinear (fracture mechanical) analysis of concrete including advanced constitutive models and strain rate effects;
    • Time-dependent resistance of concrete subject to sustained load
    • Time-dependent resistance of concrete subject to fatigue;

  • TG4.7 - Structural Applications of Recycled Aggregate Concrete – Properties, Modeling, and Design

    The main objective of the TG is to formulate design recommendations for the structural use of RAC. This will take the form of proposing new or adjusting existing expressions and models for mechanical and structural properties of reinforced and prestressed concrete structures.

    To achieve this goal, the TG will first perform a comprehensive critical review of literature alongside a preparation of databases of experimental results regarding mechanical and structural properties of RAC. Where necessary and possible, identified gaps in existing results will be complemented by new studies of TG members within existing or new research projects. Based on this work, the TG will formulate expressions and models for the following:

    • Physical properties of RAC – density, water absorption, permeability
    • Mechanical properties – compressive strength, tensile strength, modulus of elasticity, stress–strain relationship, fracture energy, shrinkage, creep
    • Durability-related properties – carbonation resistance, chloride ingress, freeze-thaw resistance, chemical attack
    • Structural behavior – flexural strength, shear strength, axial strength, punching strength, seismic resistance, fire resistance, deformation, cracking, bond and anchorage
    • Fire resistance of RAC and RAC structures – resistance under fire and residual resistance after exposure to elevated temperatures of RAC and reinforced and prestressed RAC members

  • TG4.8 - Low-carbon concrete structures

    Decreasing the environmental impact of concrete structures is an objective put forward by almost all the actors involved in the domain of construction. Although cementitious materials intrinsically involve low embodied energy, their use in large volumes in worldwide construction lead to approximately 8% of global CO2 emissions. Portland cement is the main constituent responsible for the environmental impacts caused by the life cycle of concrete, as it generates on average more than 800 kg CO2/t of clinker.

    The task group will have two main objectives:

    1- Identify the different ways to obtain low-CO2 concretes among the different possible routes:

    • Evaluate which ones are rapidly reachable and how far we are from an universal utilization of these concretes.
    • Define the work to carry out to bring these concrete at an industrial level.
    • Estimate the scientific, technical and economical obstacles and challenges that could retard the implementation and acceptances of such concretes.

    2- Evaluate the consequences of these low-CO2 concretes on the design of concrete structures, in terms of:

    • Durability, for instance the impact of these new concretes on carbonation and chloride ingress, the most widespread problems facing reinforced concrete worldwide.
    • Structural design, with the verification of the applicability of the international codes (Eurocodes…). The part concerning creep and shrinkage will be developed in the new COM4/TG Time dependent behavior of concrete.
