IS 2720 : Part 41 : 1977 : Methods of test for soils: Part 41 Measurement of swelling pressure of soils

1. SCOPE

1.1 This standard covers the laboratory method of conducting onedimensional swelling pressure test using either fixed or the floating rings on both undisturbed or remoulded soils in the partially saturated condition to determine thtloSwelling pressure of the soil. Two methods, namely, consolidometer method in which the volume change of the soil is permitted and the corresponding pressure required to bring back the soil to its original volume is measured and the constant volume method in which the volume change is prevented and the consequent pressure is measured are covered.
