Cemented Material Dams: Design and Practice. Cemented Soil Dams / Barrages en Matériau Cimenté: Conception et Réalisation. Barrages en sol cimenté (Icold Bulletins Series)

The Cemented Material Dam (CMD) is defined as a series of new dam types utilizing cementitious binder together with various natural or manufactured materials in the construction of a dam. The principles used to design the dam section are different from those used in conventional gravity, rockfill and embankment dams. CMD dams offer the possibility to build dams safely, quickly and economically in an environment-friendly way, to decrease the risk of overtopping failure and the associated flood caused as much as possible, as well as to adapt, in some of the CMD types of dams, conventional “concrete” gravity dam design to foundation conditions usually not acceptable for concrete gravity dam structures. CMD is still in an early stage of development. Further optimization is needed in material preparation, structural design and construction processes to achieve a more uniform level of safety, a cheaper way to build dams with respect to different local materials, and a faster way of construction for different dam foundations. ICOLD Bulletin 195 is the second of a series of planned bulletins, and introduces material properties (binders, soils), properties of cemented soil, structural design of a Cemented Soil Dam (CSD), investigation, construction, quality control and performance. Le barrage en matériaux cimentés (CMD) est défini comme une série de nouveaux types de barrages utilisant un liant cimentaire ainsi que divers matériaux naturels ou manufacturés dans la construction d'un barrage. Les principes utilisés pour concevoir la section du barrage sont différents de ceux utilisés dans les barrages-poids, en enrochement et en remblai conventionnels. Les barrages CMD offrent la possibilité de construire des barrages de manière sûre, rapide et économique dans le respect de l'environnement, de réduire autant que possible le risque de rupture de franchissement et les inondations associées provoquées, ainsi que de s'adapter, dans certains des types de CMD. Pour les barrages, la
