  • Maximum Dry Density of Soil and Optimum Moisture Content Test

    2020-02-09  Compaction Curve of Soil – Maximum Dry Density and Optimum Water Content. The compaction curve is the curve drawn between the water content (X-axis) and the respective dry density (Y-axis). The observation will be initially an increase of dry density with an increase in the water content. Once it reaches a particular point a decrease of dry density is observed. The maximum peak point

  • Determine The Maximum Dry Density And The Optimum

    The percentage moisture content corresponding to the maximum dry density on the moisture content/dry density curve should be reported as the optimum moisture content and quoted to the nearest 0.2 for values below 5 percent, to the nearest 0.5 for values from 5 to 10 percent and to the nearest whole number for values exceeding 10 percent.

  • Soil Moisture Content-Dry Density Relationship

    At one point of time, the volume of air in the soil sample becomes minimum and dry density of soil becomes maximum. This is called maximum dry density point at this point the addition of water should be stopped. The moisture content corresponding to the maximum dry density of soil is called as “ Optimum moisture content ”.

    This specification is usually that a certain percentage of the maximum dry density, as found from a laboratory test (Standard or Modified) must be achieved. For example we could specify that field densities must be greater than 98% of the maximum dry unit weight as determined from the Standard Compaction Test.

    Crushed rock is generally more stable than natural rounded stone. A 36% increase in rock size is recommended for rounded rock. The rock should be durable and resistant to weathering, and should be proportioned so that neither the breadth nor the thickness of a single rock is less than one-third its length. In most situations the nominal rock size is usually between 100 mm to 450 mm. Maximum ...

    Above this height, the density of air no longer works as effectively to remove heat. As a result the functional kVA of the transformer must be reduced at higher altitudes, typically about .3% for every 100m/330′.
