we are selling Natural River Sand in Bangalroe
Sand, as one of the most accessible natural resources, has been used mostly as a constructionmaterial since the earliest days of civilization. It is defined as “continuously graded unconsolidated material (sediment) present on the earth's surface as a result of the natural disintegration of rocks. The top most mantle of earth, which was once rock, has been transformed to soil by natural forces of weather .Texturally soil is not one material but a compound of three ingredients, derived from the same parental rock . They are sand, silt and clay. Though mostly soil occurs as a combination of the three materials, there are places where stretches of sand do occur alone where building activity has to be carried out.
River sand is used in the construction industry mainly for concrete production and cement-sand mortar production. River sand is obtained by dredging from river beds. It has the major
characteristics that since it has been subjected to years of abrasion, its particle shape is more or less rounded and smooth, and since it has been subjected to years of washing, it has very low silt and clay contents.Research to use sea sand for construction, especially, using sea sand to make the cement concrete is aimed to exploit maximally the potential of a local material being available, cheap for socioeconomic developing and prevent from its harmful impaction.
However the study to use sea sand cement concrete is a big problem of civil engineering field. In many countries sea sand have been using for making cement concrete since long time ago, naturally, its technology depends on the research achievement and specific conditions of each country. When sea sand is mixed with cement in place of normal river sand to make concrete for buildings, the high content of chloride in sea sand leads to structural integrity problems. This composition absorbs humidity with causes erosion and rusting in the steel rods used in reinforced concrete. The building structural integrity is therefore damaged.Buildings made with reinforced concrete containing sea sand can only last 6-10 years before they must be abandoned. The root cause of structural failure is the high chloride content in the sand. Only with costly special treatment of sea sand can chloride be reduced to a safe level. Because of the chloride content in sea sand reinforced concrete.
