2.1 The liquid limit of a soil is the moisture content, expressed as a percentage of the weight of the oven-dried soil, at the boundary between the liquid and plastic states of consistency. The moisture content at this boundary is arbitrarily defined as the water content at which two halves of a soil cake will flow together, for a distance of

Atterberg limits include liquid limit, plastic limit, and shrinkage limit. The standard method of determination of Atterberg limits are stated in BS 1377 : Part 2 : 1990. According to BS, the soil tested by Atterberg limits should not be oven dried, it is because drying the soils in different degree will alter their properties significantly.

For all the Atterberg limits tests, soil samples consist of material passing a No. 40 (425m) test sieve and are prepared for each test using wet or dry methods described in the standards. Moisture in Test specimens is adjusted by adding water, mixing with a spatula, and allowing to condition for at least 16 hours.

Mar 14, 2012 The variation of limits of air dried and oven dried soils is shown in Fig. 7. It is observed that there is very little effect of drying on the plastic limit and shrinkage limit of soils. A larger reduction in liquid limit and small change in plastic limit due to drying resulted in decreases of plasticity index as shown in Fig. 7.

Mar 23, 2017 A. Atterberg defined the boundaries of four states in terms of limits. A fine-gained soil can exist in any of several states; which state depends on the amount of water in the soil system. When water is added to a dry soil, each particle is covered with a film of adsorbed water. If the addition of water is continued, the thickness of the water film on a particle increases.

Plastic Limit is the soil water content at the boundary between the semi-solid state and plastic (flexible) state. It is determined as the gravimetric water content at which a soil sample can be rolled by hand into a thread of 3.2 mm diameter without breaking. Moisten the sieved soil sample so that it can be easily rolled between your hands.

The shrinkage limit is determined as follows. A mass of wet soil, m 1, is placed in a porcelain dish 44.5 mm in diameter and 12.5 mm high and then oven dried. With oven-dried soil still in the dish, the volume of shrinkage can be determined by filling the dish with mercury. The volume of mercury that fills the dish is equal to the shrinkage volume.

The shrinkage limit is less frequently used than the liquid and plastic limits. The shrinkage limit is determined as follows. A mass of wet soil, M 1, is placed in a porcelain dish 44.5 mm in diameter and 12.5 mm high and then oven-dried. The volume of oven-dried soil is determined by using mercury to occupy the vacant spaces caused by shrinkage.
