Abstract:

La consommation de béton devient de plus en plus importante en raison d'une urbanisation accrue nécessitant la réhabilitation et la construction de bâtiments et d'infrastructures. Néanmoins, la production de béton qui doit accompagner le développement urbain entraîne des problèmes environnementaux relatifs à la préservation des ressources naturelles qui ne sont pas inépuisables. Malgré des efforts de recyclage, la plupart des matériaux recyclés sont généralement utilisés pour les travaux routiers ou de remblai. En s'inscrivant dans le Projet National Recybéton (PN), ce travail de thèse a pour

Abstract:

Les granulats de béton recyclé (GBR) ne sont pas suffisamment utilisés dans le secteur de la construction, principalement en raison de leur grande capacité d’absorption d’eau. Ces matériaux sont en effet composés de granulats naturels concassés et de pâte de ciment durcie adhérente qui possède une forte porosité. La première partie de ce travail de recherche s’intéresse à la valorisation des GBR de dimensions inférieures à 4 mm (sables recyclés) dans une formulation de mortier. Les comportements à l’état frais et durci de mortiers fabriqués soit avec un sable recyclé soit avec un sable naturel

Abstract:

La valorisation de déchets de démolition en tant que granulats à béton présente un double objectif de préservation des ressources naturelles et de désengorgement des sites de stockage. Les granulats recyclés de béton présentent la particularité de contenir du mortier résiduel qui influence certaines de leurs propriétés et, par voie de conséquence, celles des bétons dans lesquels ils sont utilisés. Cette thèse a pour but de développer l’utilisation de bétons de granulats recyclés en remplacement total des matériaux naturels. Elle a été réalisée en partenariat industriel avec l’entreprise CHRYSO

Abstract:

Le béton, largement utilisé dans la construction, est essentiel à la société moderne. Cependant, lorsque les bâtiments arrivent en fin de vie, la démolition devient inévitable, contribuant ainsi à l'accumulation annuelle des débris de béton. Cette situation pose un défi majeur en matière de gestion des déchets de construction. Face à cette réalité, le recyclage du béton émerge comme une nécessité. Cette approche permet non seulement de réduire la quantité de déchets envoyés en décharge, mais aussi de préserver les ressources naturelles, favorisant une construction plus durable.

Abstract:

In the process of crushing concrete waste, significant amounts of fine by-products, the so called fine recycled concrete aggregates (FRCA), are generated and excluded from potential use. Limited research has thoroughly investigated the performance of concrete mixes with FRCA, very likely due to the complexity in analysing non-negligible amounts of adhered residual cement paste (RCP). Although some studies have proposed promising sustainable mix-design procedures accounting for the different microstructure when using coarse recycled concrete aggregates (CRCA), no similar approach exists for FRC

Abstract:

The use of recycled aggregate in the production of self-compactig concrete (SCC) is relatively recent. Few studies have been developed, but, there are numerous advantages in its application. The recycled lightweight self-compacting concrete (RLSCC) offers several advantages of SCC, due to the self-compacting properties, it absorbs construction residues, in the use as recycled aggregates, and the lightness due to the smaller specific mass of the recycled aggregates, it promotes the reduction of the loads due to the own weight . However, studies carried out in concrete with recycled aggregates (

Abstract:

The use of recycled concrete aggregates (RCA) has gained increased attention in the past few decades as an alternative to decrease the carbon footprint of concrete construction. Yet, most of the research performed so far demonstrates that RCA concrete displays inferior performance in the fresh and hardened states when compared to conventional concrete (CC). The latter is believed due to the fact that very often the different microstructure of RCA is not accounted for while the mix-proportioning of RCA concrete. Recently, a number of mix-design procedures accounting for RCA microstructure have

Abstract:

With more than three tons per head, per year, concrete is the most important and widespread material used in construction worldwide. The Italian code allows the use of waste produced by construction and demolition (C&D) operations to produce recycled aggregates. The great interest, both technical-economic and environmental aroused by this subject has in recent years and all over the world led to a noteworthy increase in experimental and theoretical studies on recycled materials resulting from the construction sector and, in particular, on recycled aggregates.

Abstract:

This research demonstrates that rubber particle size affects concrete workability and water permeability to a greater extent than fresh density and strength. Concrete with rubber particles of larger size tends to have a higher workability and fresh density than that with smaller particle sizes. However, rubber aggregates with smaller or continuously graded particle sizes are shown to have higher strengths and water permeability resistance. Influence of recycled aggregate and rubber aggregate as part substitutions for natural aggregates on concrete compressive strength was investigated and four

Abstract:

In order to reduce the use of landfilling within waste management great emphasis is being placed on waste reduction and recycling. Each year in the UK approximately 2.5 Mt of waste glass is produced and approximately half of this waste is not recyclable. Therefore alternative ways need to be found for using waste glass and one possibility is to use it within concrete as a replacement for cement and/ or aggregate. In the research programme concrete mixes were tested which had 0%, 25%, 50% and 100% of the fine aggregate replaced by crushed waste glass. All glass was originally in bottle form and

On the other hand, huge amount of construction discards are produced every year, causing pollutions and destructions to the environment. Secondly, dumping grounds for construction discards are difficult to find.
