A plot of plasticity index against liquid limit is known as the plasticity chart, and on it a large number of soils plot on or near to a line, known as the. A-line, cutting
10 Oct 2014 6.1 The soil is classified as clayey gravel, GC, or clayey sand,. SC, if the pair of values (wL, IP) in the plasticity diagram is situated above the A line casagrande-plasticity-chart. The A – line in the chart has the equation Ip = 0.73 ( WL – 20). This A – line generally separates the more clay-like materials from 10 Jul 2019 Key words: plasticity of clays; base hardness; cone penetration method of high plasticity dispersed around the A line of the Casagrande chart. A new line on plasticity chart was e hundred plasticity tests. The swelling characteris system developed by Savage (2007).

Unified Soil Classification System (USCS) Plasticity Chart Note: If the results of your soil tests fall above the U – line on the plasticity chart, you should be suspicious of your results and repeat your tests.
Clays generally plot above the plasticity chart’s A-Line, whereas silts generally plot below it. Notable exceptions are the kaolinitic and allophanic clays which plot below (Casagrande, 1948; Wesley, 2009). The A-line on the Plasticity Chart separates the clays from the silts. Any material whose values of PI vs. A consideration of the A-line in the plasticity chart by casagrande [1990] Komoto, T. (Saga Univ. (Japan). Faculty of Agriculture) The chart is divided into two ranges of liquid limit, low (L) and high (H). The A-line may be mathematically repre-sented by Equation 1.5: Ip = 0.73(w L – 20) SILT (M) plots below the A-line and CLAY (C) above the A-line on the plasticity chart, i.e. silts
The loss in weight of the soil in each tare, due to drying, is recorded as the weight of water. (1) A desiccator is used to cool the dried soil samples before weighing. The hot samples, if placed immediately on the balance, cause convection currents in the air which can cause serious weighing errors.

1 Oct 2009 plasticity chart as straight lines parallel to the ¶A· line. Fat or plastic clays plot above the line. Organic soils, silts and clays containing a large Originally all soils that plotted below the A-line of the plasticity charts were classified as silts. The term 'M-soil' has been introduced to classify soils that plot below the A-line but have particle size distributions not wholly in the range of silt sizes. Clays generally plot above the plasticity chart’s A-Line, whereas silts generally plot below it. Notable exceptions are the kaolinitic and allophanic clays which plot below (Casagrande, 1948; Wesley, 2009). The A-line on the Plasticity Chart separates the clays from the silts.
