A 1,000 cc container was just filled with sand in its loosest possible state and then the container was filled at the densest possible state. The dry masses of sand occupying the container space were 1,520 g and 1,830 g respectively. The sand in-situ has a void ratio of 0.64. If the specific gravity of solids is 2.65, find the relative density.

Q: A loose uncompacted sand fill 5 ft in depth has a relative density of 40%. Laboratory tests…

A:

Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.
