Review of Research on Properties of Cemented Sand Gravel Materials
Cementitious sand and gravel is a new type of dam cementing material between concrete and rockfill.It has the advantages of saving resources,reducing cost and protecting environment.The study of the characteristics of cementitious sand and gravel materials is the key to the design of dam structure.At present,there is a lack of comprehensive understanding of the characteristics of cementitious sand and gravel materials.In order to make the cementitious sand and gravel material better applied to practical engineering,through literature review,this paper summarizes the mechanical properties of cementitious sand and gravel materials and the durability of materials under freeze-thaw environment are summarized,and the characteristics of cementitious sand and gravel materials are comprehensively analyzed by the influence of various parameters such as rubber dosage,unit water consumption,water-glue ratio,sand rate,age,etc.,so as to provide a theoretical basis for further research and application of cementitious sand and gravel damming materials.
