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

How the soil which can be compacted be brought to its optimum moisture content?
Add water in the soil and make it wet uniformly.Now by the hand test squeeze the soil in your handThe soil should retain the shape and when its dropped it'll break down in three or four pieces.Soil is now at the optimum moisture content and is ready to be compacted.
Optimum moisture content of different soils?
the water which is added in the soil should be usefull for compaction of soil to know the dry density of the soil
What is the optimum moisture content in clay?
It depends on the type of clay.
What is the optimum moisture content in polyester yarn?
Polyester holds on to only about 0.4 percent of moisture; cotton just 7 percent.
What is the main purpose of compaction testing in geotechnical engineering?
The main purpose of compaction testing is to find the optimum moisture content of a soil. The optimum moisture content is that which will give the maximum dry density (and hence maximise shear strength and bearing capacity, as well as reducing settlement, porosity and permeability).** This reduction in permeability will effect the time taken for excess pore pressures to dissipate and so will have an effect on the time taken for consolidation to occur.Source:Craig, R.F. (1997). Soil Mechanics. Sixth Edition. Chapmen & Hall, London.
How much does 1 cup of Potting soil weigh in grams?
That depends greatly on the moisture content of the soil.
What are the variables used in growing a plant?
sunlight, soil mineral content, humidity, soil moisture level, altitude.
How much top soil can a semi dump trailer hold?
It depends on the moisture content of the soil. However, typical DOT permitting for a semi is 80,000 lbs gross. So it depends on the tare weight of the rig and moisture content of the soil. For sandy soil with moisture contents around 15-20%, you will average about 27 tons or 54,000 lbs pounds US.
What is the volume of one ton of topsoil?
Depends on the moisture content and the type of soil.
How do you say soil has water content in?
The water content of soil is expressed as a percentage, i.e. the percentage of the soil that is water. To calculate, weigh the mass of a sample of soil. Let this be W. Then dry the soil in an oven (be careful not to burn it) and weigh the dry soil. Let this be D. The soil moisture content, M = W-D/W x 100.
What is the weight of a unit of soil?
You need to know the soil type, moisture content, density. There is no standard unit. Find an average density first.
Why is moisture content of soil important in construction?
water content is an important property to establish relationship between the how soil behaves and its properties.consistency largely depends upon water content.also it helps in phase relationship.
