New Type of Dam-Cemented Material Dam and Current Research Progress Related
CSG dam (Cemented Sand and Gravel dam), Hardfill dam, masonry dam, and etc.are dam types developed for many years.Cemented Material Dam (CMD) is proposed as a new type of dam based on summarizing previous experience and promote safer, quicker construction, lower investment and environment-friendly technologies based on new understanding from studies and project application.CMD is constructed with Cemented Material under new concept of optimizing dam structure to make better use of local materials, comprising CSG dam, hardfill dam and Rockfilled Concrete (RFC) dam.Cemented material is a composite construction material with certain compressive strength and shear strength composed primarily of aggregate (including nature or man-made sand, coarse gravels, crushed rocks, rocks and etc.), cement materials (including cement and fly ash or slag cement, mortar, concrete and etc.) and water.The diameter of aggregate used for CMD can be from very fine material like soil to large rock with diameter more than 30 cm.Material used for CMD can be treated with simple screened, simple gradation, simple mixed but compacted with roller like RCC.Studies on design and construction of CMD are introduced in this article.
