This section describes the laboratory procedure for determining the liquid limit of soils using the device specified in Sectionsecuring the results of at.
The liquid limit (LL) is conceptually defined as the water of the liquid limit is based on standard test procedures described below. The precise definition of the liquid limit is based on standard test procedures. Liquid Limit can be determined using the Casagrande cup method, which is widely.
Soils when wet retain water, and some expand in volume. Soils with high activity are very reactive chemically.
To Determine Liquid Limit of Soil & Plastic Limit of Soil Lab Experiment Method
Slope analysis mass wasting landslide Deformation monitoring automated. Engineering Properties of Silt and Clay. Container number.
Take a representative slice of the soil sample, about the width of the spatula, at right angles to the groove.
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. This test method covers the determination of the liquid limit, plastic limit and plasticity index of soils.
Liquid Limit Test of Soil by Casagrande Method.
The liquid and plastic limits of soils are often referred the as.
The device may be operated by either a hand crank or electric motor. The precise definition of the liquid limit is based on standard test procedures described below. Take a representative slice of the soil sample, about the width of the spatula, at right angles to the groove. As the moisture content falls due to evaporation, the thread will begin to break apart at larger diameters.
Soils with high activity are very reactive chemically.
Depending on its water contenta soil may appear in one of four states: solid, semi-solid, plastic and liquid.
