Determine at leats four points at different moistire content and plot a curve.
Maximum value of dry density of river sand is 1.7 gm/cc
The water content corresponding to the maximum dry unit weight or maximum dry density is know that as optimum moisture content.(o.M.c.) or optimum water content (o.w.c) maximum dry density is achieved at higher O.M.C.for cohesive soils or fine grained soils s compared to cohesionless soils.(sand 6-10%0
i have bulk desity of soil and have natural moisture how can i get unit weight of soil
That depends on the type and grade of the sand
The weight of 1 cubic meter (cum) of dry sand is typically around 1,600 to 1,700 kilograms, depending on the specific density of the sand.
sand replacement method is used for determining the dry density of soil
The density of sand varies depending on what minerals the grains of sand are made of, and wet sand is denser than dry sand. As a rough rule of thumb, a litre of dry sand weighs about 1500 grams.
It depends on the density of the sand, between about 1.4 tons dry, 1.7 tons rammed, dry. Wet sand will be heavier.
Proctor NumberThe maximum dry density of a sample of material
It will depend on (a) the bulk density of the dry sand and (b) the moisture content of the wet sand.
The dry sand density refers to the mass of sand per unit volume when it is not saturated with water. It affects the stability of structures built on sandy terrain because denser sand can provide better support and stability for the structures. Structures built on sand with higher density are less likely to settle or shift, reducing the risk of structural failure.
Density of sand can vary depending on the grain size and moisture content and how tightly it is compactedIf you dont need very accurate densities the following should helpSand, wet 1922 Sand, wet, packed 2082 Sand, dry 1602 Sand, loose 1442 Sand, rammed 1682 Sand, water filled 1922 Sand with Gravel, dry 1650 Sand with Gravel, wet 2020density of sand will vary depending upon the condition.that is for wet,dry,gravel..
