the most of natural sand in iraq contains high sulfur trioxide (so3) which is results show the effect river sand on the mechanical properties positively until 25
the aggregate characteristics are influence the workability bleeding and segregation and durability of concrete. fine aggregates may be natural sand, crushing
the properties and chemical content of sand and water are important characteristics that govern the development of the compressive strength and durability of
cement concrete and mortar. usually, natural sand, which is made by natural enduring of rocks over many years, is preferred as fine aggregate. the economic
concrete contains natural sand obtained from riverbeds as fine aggregates. in recent times with a boost in construction activities, there is a significant increase in
sand derived from a rock, in which the grains separate along their natural boundaries. this includes unconsolidated sand or a soft sandstone where little
concrete with manufactured and natural sand in varying now-a-days due to constant sand mining the natural sand is table1: physical properties of cement.
volume of concrete consumed by the construction industry is very large. in india, conventional concrete contains natural sand obtained from riverbeds as fine
properties of m sand the bulk density of crushed sand is 1.75 gm/cm3. the specific gravity of crushed sand is 2.5 to 2.9 and it depends on the parent rock. while
the natural sand particles are well-rounded and are usually nearly spherical. spherical particles decrease the percentage of voids within the
partial replacement of natural river sand with crushed rock sand in concrete production. global engineers & technologists review , 3(4), 7-14.
the availability of natural sand for concrete production is facing perform as well or better than natural sand by utilizing its intrinsic properties.
the results show the effect river sand on the mechanical properties positively until 25 but this this behavior becomes negatively when this value becomes higher
molding sand should have ample strength so that the mould does not collapse or get partially destroyed during conveying, turning over or closing. this property
