As there are many correlations linking the liquid limit directly or indirectly with various engineering properties of the soil, the accurate determination of the liquid limit is quite essential. Generally, two methods, i.e. Casagrande’s and fall co

The controlling factors of the swelling of bentonites and its effects on the hydraulic conductivity of soil-bentonite mixtures were investigated using fifteen types of bentonites with a wide range of swelling capacity. The free swell of the bentonite

A mixture of bentonite and locally available soil is used as a clay liner material in the waste disposal site. Due to the high swelling and low hydraulic conductivity capacity, bentonite is preferred as a liner material. Since bentonite is available
