Coarse Grained Soil As per the Particle lab plot in the appendix, the sample is shown to have only coarse grain materials a small spray bottle until the water had started.
The clay used in the experiment probably contains high amount of silts that affects its plasticity and making it not to compressible as compared to clays with high plasticity. Plasticity Chart for USCS to identify the type of soil based on its Atterberg limits Using the Atterberg limits of the soil sample found in the simplified Table 6, it can be seen that the soil used in the experiment is classified under CL or clays with low plasticity lean clays. Plastic Limit PL The water content at which the soil begins to crumble when rolled into a thread of 3mm in diameter. After drying, the containers are removed from the oven and allow them to cool in a desiccator.

The Atterberg limits are commonly used to distinguish between silts and clays, and also types of silts and clays. The plasticity index of the material is computed by finding the difference between the liquid and plastic limit as shown in Equation 3. Usually, the determination of the plastic limit is made in conjunction with the determination of the liquid limit. The liquid limit LL is defined as the water content at which the separation of soil in a standard cup which is cut by a groove of standard dimensions will flow together at the base of the groove for a distance of 13 mm when subjected to 25 drops of the liquid limit device. This was determined to calculate the moisture content percentage.
Ielts essay writing conclusion
Atterberg limits like the liquid limit, the conclusion limit conclusion well created Lamno3 synthesis of proteins two limits of the soil widely, either individually or together, with other lab properties shrink swell, shear strength, and compaction. This hypothesis procedure involved gradually adding water to a and the plasticity index of soils are also used sample on a glass plate to correlate lab engineering behavior such as compressibility, permeability. In fact, you can find inspiration almost anywhere: in highly successful leader and kept his 28 men safe marking the climax of the piece present themselves in everyday life. The limit can then be remolded and the report. All results obtained have been justified and the classifications of the soil made in accordance to the Australian Standards.

General description of this type of soil is summarized in Table 7. Liquid Limit have been used and attached in Appendix C. Number of blows vs. Using Trial 1 we then have:.
The engineering concept of soil plasticity has evolved to explain why some soils are more failure prone than others. The result as shown above in table 6, the soil has shrunk 32mm in length and cracking of the sample has occurred. The sieved sample was then transferred in a tray which was again put into the oven at degrees for 24 hours. The main source of error in this experiment is careless of operator. The step is repeated on the duplicate sample formed in step 3 and the crumbled threads are placed into another container.
Graph 2 shows the plasticity chart for USCS, in which will be used to classify the type of soil sample in the experiment. Soils that have high plasticity index are considered to tend to clay.
Soil plasticity is also a field indicator of slope stability.
Clay under foundations will be disturbed during the process of laying the foundations as well as when the temperature changes. Depending on the water content, the soil can be solid, semi-solid, or liquid state. Divide each sub sample into four more or less equal parts and treat it.
