The Liquid Limit (LL or w LL), also known as the upper plastic limit, is the water content at which the soil changes from the liquid state to a plastic state. It is the minimum moisture content at which a soil flows upon application of very small shear force.
Liquid limit is the water content where the soil starts to behave as a liquid, measured by a standard cup and spatula. Learn how to perform the liquid limit test, its significance, and its relation to other soil properties and engineering problems.
The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit. Depending on its water content , soil may appear in one of four states: solid, semi-solid, plastic and liquid.
Liquid limit. The liquid limit corresponds to a water content at which soil material begins to flow and closes a groove of standard width. The liquid limit is determined with a cup that is filled with soil paste. The cup is lifted and dropped from a specified height.
1 Ιαν 2018 · Definition. The water content at which a soil-water paste changes from a plastic to a liquid-like consistency as indicated by the behavior of a standard groove carved into a pat of soil molded into a round-bottomed brass cup which is part of a standard liquid limit test device.
Liquid Limit (LL) 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 when jarred in a specified manner. Plastic Limit (PL) is the water content at the change from a plastic to a semi-solid state.
7 Μαρ 2015 · Liquid limit is the minimum water content at which soil is in liquid state and has a small shearing strength. Learn how to determine liquid limit of soil using casagrande or cone penetrometer apparatus and why it is important for soil classification and analysis.
