DETERMINATION OF THE ATTERBERG LIMITS USING A FALL CONE DEVICE ON LOW PLASTICITY SILTY SANDS

The Fall cone liquid limit testing procedure for low plasticity soil mixtures with sand, including the sample preparation and implementation of plastic determination suggestions are covered within this research. A apparatus was used in order to determine limits types, which Casagrande cup thread rolling methods proved inapplicable. Several issues addressed concerning standardized mixture filling procedures testing, as well applicability single measurements per moisture content effect curing time on data gain quality. Both results show a solid expected linear trend high precision. Liquid correlate existing suggests method unique clays sand. Plastic deviation from values obtained classical Casagrande’s could be caused by bias tested type or apparatus. Test presented numerically graphically discussed focus given determining Atterberg
