The international conference of Concrete and Circular Economy (CCE) is scheduled in terms of natural resources sustainable management and environment preservation as the world is leading a massive transition to circular economy by reusing/valorising the millions of tons of concrete wastes resulting from the buildings and infrastructure demolition and precast concrete industry.
CCE2025 is a great occasion to civil engineering researchers and industrials to share their findings in the field of waste valorization within concrete manufacturing.
As part of this congress, several topics will be discussed and a promising four days’ technical program is expected based on keynote lectures delivered by high selected speakers and including oral sessions and poster participations.

Novel Approaches Towards the Sustainable Management of Concrete Civil Infrastructures
Abstract
The scope of this lecture is to indicate novel approaches and provide some examples on how sustainability should be included on the operation and management of concrete civil infrastructures, namely when concerning building materials and building construction. Concepts as resilience based management, towards increasing the preparedness and adaptability of the built environment to an hazard (or multi-hazard scenario), in face of climate change, will be duly provided. Also, their connection with quality control and life cycle approaches will be provided, with a focus on concrete structures. All these applications are supported by simple examples, some of them from previous and running R&D projects, and some good practices are indicated within the lecture.

Sustainable and Resilient Built Environment in a Changing World - Challenge for Concrete Structures
Abstract
Recent developments and changes in the natural and socio-economic environment require new technical solutions for the construction of new buildings and the modernisation of existing ones. Buildings, infrastructure and the entire built environment should be better prepared for new conditions – they should be sustainable, resilient and adaptable to new situations.
Concrete is the second most widely used material in the world after water. This raises the need to save resources for new concrete and to recycle old concrete structures within the framework of circular principles.
Concrete and new advanced types of silicate composites, including the use of recycled components, are gradually becoming building materials with a high potential for new technical solutions that lead to the necessary reduction of environmental impact and subsequent social and economic improvement.
The lecture will present the implementation of the sustainability and resilience approach to the development and design of concrete structures using the principles specified in the new fib ModelCode 2020 (MC2020). This new ModelCode not only addresses traditional requirements for safety and serviceability, but embraces sustainability, which is becoming a paramount core requirement responding to broader issues such as social responsibility, environmental quality and economic efficiency.
Some examples of research results and examples of specific structures contributing to a sustainable and resilient environment will also be presented.

Valorization of natural resources and industrial by products in ecological hydraulic binders
Abstract
With the increasing of cement production, the depletion of natural resources, energy consumption and greenhouse gas emissions related to its manufacturing are becoming worrisome. Indeed, cement production is responsible for approximately 5 to 8% of the total CO2 emitted, associated with global warming. It is therefore imperative to develop low-carbon cements that are less energy consuming, while promoting recycling and using certain industrial wastes and by-products as raw materials in this sector.
In this context, we are working on families of cements, called low carbon by substituting part of the clinker, prepared by a heat treatment at 1450 °C, with clays or by-products (blast furnace slag, sand washing waste, dam sediments, etc.) calcined at moderate temperatures (< 900 °C). Depending on their nature, the latters are likely to present hydraulic reactivity (called pozzolanicity). Another way of valorizing these by-products is to incorporate them as raw material for clinker manufacture.
Furthermore, we are intersted by the synthesis and characterization of a new family of ecological materials called geopolymers by acid or basic activation of aluminosilicate materials, mainly local clays.

Valorization of agro-wastes in cementitious composites
Abstract
The construction industry has a high environmental footprint and the world objective of reaching Greenhouse gases (GHG) net zero by 2050, in order to keep a limit of 1.5 °C temperature rise, could not be realized if the construction industry is not decarbonized through the development of sustainable low carbon materials. The reuse of waste from construction and demolition as well as waste from other industries in the fabrication of environment friendly building materials could help reducing the negative impact of the construction industry. In this paper, the valorization of local agrowaste available in North Africa in combination with local supplementary cementitious materials (SCM) such as slag and natural pozzolan is discussed. The use of cork as aggregate in cementitious composites for insulation purposes and the use of natural fibers such as alpha and date palm fibers in cementitious repair mortar to reduce shrinkage and cracking are presented.
