Book excerpt: L'objectif principal du travail présenté est la compréhension de la relation liant le flux de chlorures mesuré expérimentalement en régime stationnaire lors d'un essai de diffusion-migration à travers un échantillon de mortier, à la valeur de courant associé. Une approche expérimentale, basée sur un protocole d'essai spécifique, a permis de comparer les courbes de chrono-ampérométries obtenues lors d'essais de diffusion-migration pour des mortiers d'épaisseurs différentes préparés à partir de différents dosages en eau. Tous les essais ont montré que la densité surfacique de courant évoluait en deux phases après ajout d'une solution contenant le chlorure de sodium : 1.Une diminution malgré la présence d'une solution plus conductrice. 2. une augmentation, malgré un flux constant, d'autant plus importante que les pores sont d'un rayon moyen plus important. Un protocole de mesure de l'impédance électro-chimique des échantillons soumis au test de diffusion-migration a fait apparaître une modification des caractéristiques électriques de ces derniers lors des polarisations en présence de chlorures de sodium. La mesure d'impédance électrochimique du matériau a permis d'accéder au taux de surface d'échange solide-liquide. Ces observations ont conduit au développement d'un modèle théorique nouveau qui permet le calcul d'un coefficient de diffusion apparent en prenant en considération les phénomènes de double couche à l'interface solide-solution, la géométrie de la matrice poreuse, les interactions ioniques, et les cinétiques de réactions hétérogènes. La confrontation des résultats théoriques aux mesures expérimentales valide les hypothèses retenues dans le modèle et souligne la prépondérance des effets électro-capillaires sur la valeur de ce coefficient de diffusion apparent.

Book excerpt: Earthen architecture constitutes one of the most diverse forms of cultural heritage and one of the most challenging to preserve. It dates from all periods and is found on all continents but is particularly prevalent in Africa, where it has been a building tradition for centuries. Sites range from ancestral cities in Mali to the palaces of Abomey in Benin, from monuments and mosques in Iran and Buddhist temples on the Silk Road to Spanish missions in California. This volume's sixty-four papers address such themes as earthen architecture in Mali, the conservation of living sites, local knowledge systems and intangible aspects, seismic and other natural forces, the conservation and management of archaeological sites, research advances, and training.

Book excerpt: CE TRAVAIL S'INSCRIT DANS LE CADRE D'UNE ACTION DE RECHERCHE CONCERTEE SUR LA DURABILITE DES BETONS. LA CORROSION DES ARMATURES DU BETON EST DUE A LA PENETRATION D'AGENTS AGRESSIFS EXTERIEURS TEL QUE LE CHLORE. LE BUT DE CETTE ACTION DE RECHERCHE EST DE METTRE EN PLACE UN MODELE TRAITANT DU TRANSFERT HUMIDITE-IONS CHLORURES DANS LES MILIEUX POREUX DU GENIE CIVIL AFIN DE PREVOIR LA DUREE DE VIE DES OUVRAGES EN FONCTION DE L'EPAISSEUR D'ENROBAGE. UN MODELE MACROSCOPIQUE A ETE ETABLI EN INTRODUISANT DES COEFFICIENTS DE TRANSFERT QUI DEPENDENT DE PLUSIEURS PARAMETRES TELS QUE LA TENEUR EN EAU ET LA TENEUR EN CHLORE. CERTAINS DE CES COEFFICIENTS AINSI QUE L'INFLUENCE DES PARAMETRES CITES PRECEDEMMENT VONT ETRE DETERMINES EXPERIMENTALEMENT SUR DES MORTIERS. NOUS AVONS TOUT D'ABORD EXPLORER L'INFLUENCE DE LA CONCENTRATION EN CHLORURE DE SODIUM (NACL) SUR LES PROPRIETES A L'EQUILIBRE. LES ISOTHERMES DE SORPTION AVEC DES MATERIAUX CONTENANT INITIALEMENT DU NACL SONT DECALEES PAR RAPPORT A L'ISOTHERME CLASSIQUE REPRESENTE PAR UN MODELE DE TYPE GAB. CE DECALAGE A ETE PARAMETRE EN FONCTION DE LA CONCENTRATION EN NACL. NOUS PRESENTONS ENSUITE L'ENSEMBLE DES RESULTATS DES DIFFUSIVITES HYDRIQUES RELATIVES AUX MATERIAUX ETUDIES EN FONCTION DE LA TENEUR EN SOLUTION ET DE LA CONCENTRATION EN NACL. NOUS AVONS EFFECTUE UN SEUL CYCLE IMBIBITION-SECHAGE. POUR LES DEUX TYPES DE TRANSFERT LA CONCENTRATION EN NACL N'A PAS D'INCIDENCE SUR LA DIFFUSIVITE HYDRIQUE. CETTE CONCLUSION DEVRA ETRE VERIFIEE POUR PLUSIEURS CYCLES AVANT DE L'UTILISER POUR ECRIRE NOTRE CODE DE CALCUL. DES PROFILS EN CHLORE ONT AUSSI ETE DETERMINES EN FIN D'IMBIBITION ET EN FIN DE SECHAGE. IL Y A ACCUMULATION DE CHLORURES FIXES PRES DE LA SURFACE DES MATERIAUX. LA CINETIQUE DE FIXATION DES IONS CHLORURES LORS D'IMBIBITIONS EST PLUS LENTE QUE LORS DE LA DETERMINATION DES ISOTHERMES D'INTERACTION. LE MOUVEMENT DE L'EAU EST PLUS RAPIDE ET EMPECHE LES IONS CHLORURES DE SE FIXER. DE PLUS ON REMARQUE QU'IL N'Y A PAS DE REDISTRIBUTION SIGNIFICATIVE DE CHLORE ENTRE LA FIN DE L'IMBIBITION ET LA FIN DU SECHAGE. LES MOUVEMENTS D'EAU LIQUIDE CONTINU SONT DONC PEU IMPORTANTS EN SECHAGE.

Book excerpt: One of the great challenges of contemporary society is establishing a sustainable way of life in harmony with the environment without compromising economic growth and technological development. On the other hand, the increase in the world population has driven per capita consumption, and consequently, the generation of waste. Because of this, new materials are being developed from different types of waste. This Special Issue aims to highlight and share recent scientific findings in the area of "New Environmentally Friendly and Sustainable Materials" manufactured from different material types (polymers, ceramics, metallics, and composites) and urban, industrial, mining and agricultural wastes. Moreover, scientific topics such as improving performance and durability, materials characterization, hybrid materials, foams and porous materials, trends and advances, and mechanical, electrical, magnetic, optical, and thermal properties will also be accepted.

Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials can markedly improve the mechanical properties of concrete, as well as reduce the porosity and enhance the durability of concrete. The application of nanotechnology in concrete is still in its infancy. However, an ever-growing demand for ultra-high-performance concrete and recurring environmental pollution caused by ordinary Portland cement has encouraged engineers to exploit nanotechnology in the construction industry. Nanotechnology for Smart Concrete discusses the advantages and applications of nanomaterials in the concrete industry, including high-strength performance, microstructural improvement, self-healing, energy storage, and coatings. The book Analyses the linkage of concrete materials with nanomaterials and nanostructures Discusses the applications of nanomaterials in the concrete industry, including energy storage in green buildings, anti-corrosive coatings, and inhibiting pathogens and viruses Covers self-healing concrete Explores safety considerations, sustainability, and environmental impact of nanoconcrete Includes an appendix of solved questions This comprehensive and innovative text serves as a useful reference for upper-level undergraduate students, graduate students, and professionals in the fields of Civil and Construction Engineering, Materials Science and Engineering, and Nanomaterials. Dr. Ghasan Fahim Huseien is a research fellow at the Department of Building, School of Design and Environment, National University of Singapore, Singapore.

Book excerpt: Ramming earth has been a method of construction for centuries in many parts of the world and the technique can produce buildings that are strong, durable, safe and desirable. Because earth is an abundant and cheap resource, rammed earth buildings are often very economical. To achieve the best results the right techniques for the selection and testing of soils must be used to protect walls from water damage and shrinkage. This book aims to show how high standards can be achieved and the criteria on which rammed earth structures and building techniques can be judged. Since the fi rst edition of this book was published, the standards described in Rammed Earth Structures has been adopted as a Building Standard in Zimbabwe. Further progress is being made extending the use of rammed earth as an officially sanctioned building material across all SADC countries. This book is now therefore becoming an important guide and resource for those wishing to employ this economical and low-carbon building material in the construction of public as well as private buildings in Africa and elsewhere.
