DIMA: Durability, Innovation and Recovery of Alternative Materials

The aim is to better understand the characteristics of construction materials comprising alternative products on three levels: durability of the structure associated with the properties of the implemented materials and the environment it is exposed to, modelling of behaviour, and assessment of the life cycle and environmental impacts in the context of a circular economy.

Challenges for society

In France, the construction sector in the broad sense, i.e. buildings and civil engineering, represents almost 10% of the Gross Domestic Product [INSEE, 2015] and provides employment for nearly 1.5 million people. In 2022, the construction industry was the 3rd largest sector generating salaried employment in France. Through its direct and indirect impacts, it supports nearly 13% of French jobs. In addition, buildings, structures and networks are changing the nature, function and appearance of our cities and regions. Their construction, use, maintenance, repair, rehabilitation and demolition consume energy and resources, and generate waste on a huge scale.

The construction sector is by far the largest producer of waste, with 360 Mt in 2010 [CGDD/ SOES, 2013]. This sector also makes a major contribution to implementation of public policies in the fields of transport (infrastructures), housing, education (schools), healthcare (hospitals), and reduction of natural risks. The construction sector is constantly seeking means and strategies to deliver social progress, environmental protection, better use of resources, economic growth and jobs. Over the last few years, sustainable development has become a policy priority reinforced by economic players, with an impact that remains difficult to assess. Today it is therefore at the centre of public and private sector actions.

 

Scientific approach

The aim of the scientific approaches is to better understand the behaviour of construction materials comprising alternative products (in particular those based on construction waste and industrial coproducts) on three levels: (i) the durability of the structure determined by the properties of the implemented materials and the exposure environment, (ii) optimisation of mixes guaranteeing appropriate mechanical performance, (iii) consideration of the life cycle and environmental impacts in the context of a circular economy.

These approaches are expressed by means of three questions formulated to represent three scientific areas:

  1. How can the specific features of materials based on alternative products (mineralogical, physico-chemical, morphological, etc.) be taken into account in modelling tools in order to predict their characteristics in the short and long term?
  2. What formulations of these materials should be used to ensure they are durable, depending on the type of use/environment?
  3. What is the advantage of using alternative materials, from an environmental point of view, and what is their contribution to the circular economy?

Different types of materials are concerned, including in particular those used within cementitious materials for engineering structures and within bituminous materials for road infrastructure networks, as well as other types of use, for which the performance requirements of construction materials are lower. The aim is to optimise recovery of certain alternative materials without reducing the structure’s durability or harming the environment.

Expected results

The main research themes implemented by UMR MCD are organised into 3 major areas applicable to different types of materials (including in particular those used within cementitious and bituminous materials).

For Area 1 - The interaction mechanisms of alternative materials:

  • Characterisation of alternative materials;
  • Laboratory formulation and characterisation of mixes in fresh condition and early age;
  • Changes in physico-chemical and mechanical properties of the material;
  • Modelling of properties over time.

For Area 2 - Durability of materials in their environment

  • New protocols for ageing of materials;
  • Durability properties of the formulated materials;
  • Models for prediction of durability properties;
  • Validation of models on structural elements.

For Area 3 - Life cycle analysis - Circular economy - Environmental impacts

  • Life cycle integration of the initial products;
  • Life cycle analysis of the initial products;
  • Life cycle analysis of the processes;
  • Life cycle analysis of the selected formulas;
  • FDES (product life cycle analysis and health information document) for structural elements.
