What Is the Difference Between Liquid Limit and Plastic Limit?
Liquid Limit Is the Water Content at Which Soil Changes from a Plastic to a Liquid State, When the Soil Specimen Is Just Fluid Enough for a Groove to Close...
.
Considering this, why are plastic limits and liquid limits important?
It is the water content at which a soil changes from plastic to liquid behavior. Those limit of soil are very important property of fine grained soil and its Value is used to classify fine grained soil and calculate activity of clays and toughness index of soil.
Furthermore, what is meant by liquid limit? The liquid limit is the moisture content at which the groove, formed by a standard tool into the sample of soil taken in the standard cup, closes for 10 mm on being given 25 blows in a standard manner. This is the limiting moisture content at which the cohesive soil passes from liquid state to plastic state.
what is plastic limit?
Plastic limit is the water content in clay soil below Which it stop to behave like a plastic material. it starts to crumble when rolled in threads of 3 mm diameter. At this water content, the soil losses its plasticity.
Why is liquid limit important?
Value of liquid limit is used to classify fine grained soil. It gives us information regarding the state of consistency of soil on site. Liquid limit of soil can be used to predict the consolidation properties of soil while calculating allowable bearing capacity & settlement of foundation.
