This document was uploaded by user and they confirmed that they have the permission to share it. Even though sieve analysis is mainly targeted to coarse grained soils, it could also be used to determine the total amount of fine particles presented in a soil sample. Hydrometer analysis of soil lab report.

Hydrometer analysis lab report discussion TITLE Particle size distribution of fine soil (hydrometer test) 1.1 Introduction In this laboratory activity, students will be exposed to the usage of hydrometer to determine the particle size distribution of a given soil sample. Hydrometers work according to the Archimedesâ Principle; a solid in a liquid feels a buoyancy force equal to the mass of the liquid displaced. The hydrometer analysis per ASTM D422 was conducted to determine the distribution of the finer soil particles of the soil sample. It is important to know that most hydrometers are calibrated on 15 0 C. For example: Total mass = 500 g Mass retained on No. Immediately, start the stop watch, and remove the top cover from the cylinder. (5.4), the variation of L with hydrometer reading is shown in Table 5-1. Here is a link to the Hydrometers Assignment webpage.

At the conclusion of the final hydrometer readings, the entire Hydrometer analysis of soil lab report conclusion. Download Sieve Analysis And Hydrometer Tests Lab Report. Note that because of the laboratory constraints, the hydrometer analysis which is used in order to identify the particle size distribution of the soil was not performed and thus the particle size distribution that was generated in this experiment is not complete. For example: Total mass = 500 g Mass retained on No. Conclusion By performing ASTM standard D422 the grain size distribution for the fine portion of a soil from Burleson, Texas was able to be determined. The sieves used in the process are the standard sieves of the US. Step 10: Tabulate the ⦠Conclusion By performing ASTM standard D422 the grain size distribution for the fine portion of a soil from Burleson, Texas was able to be determined. The hydrometer analysis is an application of Stokesâ law that per- mits the calculation of the grain size distribution in silts and clays, where the soil particles are given the sizes of equivalent spherical particles. 6. This therefore means that the acquisition of a percentage of particles of a certain equivalent particle diameter has been calculated. Here is a link to the Hydrometers Assignment webpage. The cumulative relief of the conclusions is to be described in the table µ ³ FDA. Determination of rotten particle size distribution PSD by sieving hydrometer. 2.11 Stirring Rod: A glass stirring rod for each beaker for mixing the hydrometer analysis sample in the dispersing agent.

Hydrometer analysis is governed by the principal of sedimentation of At no time should read specimen extend anywhere the mouth ring or extension collar. This experiment involves the hydrometer analysis of fine soil which passes through the No. CONCLUSION As a conclusion based on my experiment, the hydrometer analysis is used to determine the grain size distribution for the fraction of soil that is smaller than 0.063mm of diameter from sieves analysis. You should consider the last section of each lab experiment as well as 1.5 Report Preparation part when writing a lab report. Hydrometer test lab report conclusion ... Canadian metric sieves⢠Water bath or constant room temperature â to keep soil suspension at or near 20°C during analysis. Sieve analysis can be performed in order to determine the grain size distribution and classify the soil according to the Unified. 200 sieve size (.075 mm). hydrometer, rinse it with distilled water and allow it to stand in a jar containing distilled water at the same temperature as that of the test cylinder. (fine-grained soils with grain size smaller than 0.075 mm) A sedimentation procedure (e.g., hydrometer, pipette, buoyancy analysis) is used for fine grained soils. Hydrometer test lab report. 4.3 Sedimentation test with hydrometer. Lab 2 Sieve and Hydrometer Analysis StuDocu. A soil sample of known weight was placed into a 1000mL-graduated cylinder with tap water, was shaken by a lab technician to uniformly suspend the soil particles, and set up right when uniform density was achieved as ⦠Here are the instructions of what you need to do for your project, listing the three sections to include, with the points that should be in each section. Dr. George Mylonakis 2005, à ¢ â ⬠Analysis â ⬠Hydrão ', The Lab Manual, The City College of New York. Soil and water are mixed ⦠The hydrometer analysis is an application of Stokesâ law that per- mits the calculation of the grain size distribution in silts and clays, where the soil particles are given the sizes of equivalent spherical particles. Hydrometer is can be used to measure fluid density and it floats due to buoyancy. (3) Calculate the percent passing (or percent finer) by starting with 100 percent and subtracting the percent retained on each sieve as a cumulative procedure. 1 0.55~ 2.3) x (hydrometer reading) L2 =14cm VB = volume of the hydrometer bulb = 67.0 cm3 Ac = cross-sectional area of the hydrometer cylinder = 27.8 cm2 Based on Eq. After the experiment, this report concludes that the soil sample that was analyzed is uniformly distributed after it passed the Unified Soil Grading Criteria. Composite correction as before 12 PROCEDURE 121 Hydrometer Analysis 1211 Use soil binder prepared. Sieve analysis can be performed in order to determine the grain size distribution and classify the soil according to the Unified. 3.The hydrometer is re-inserted in the suspension and readings are taken after periods of 8, 15 and 30 minutes; 1, 2 and 4 hours after shaking. Stop shaking and allow it to stand. Tables 1 and 2 both show the raw and processed data for sieve and hydrometer analysis. This investigation will review the volume of passengers using the Monash University Clayton-Caulfield inter-campus bus in order to recommend adjustments to the service if needed. This A hydrometer analysis is a measurement method used to determine soil particle size in a sample. Alexa Paige Oscar Martinez CE 3211 â 006 February 7, 2019 Hydrometer Analysis. The hydrometer is gently lowered into the liquid until it floats freely. Hydrometer Test for Grain Size Analysis on soil from Burleson, Texas. In this experiment, we will investigate the specific gravity of liquids via construction of a hydrometer.

The density of a liquid is to be measured using a hydrometer. The hydrometer analysis per ASTM D422 was conducted to determine the distribution of the finer soil particles of the soil sample. The hydrometer should float freely and not touch the wall of the sedimentation cylinder. (2) Calculate the percent retained on each sieve by dividing the weight retained on each sieve by the original sample mass. A hydrometer is a device designed to measure the relative density of a liquid which refers to the ratio of the actual density of the substance to the density of the water. Insert a rubber ball or any other suitable cover on the top of the 1000 ml measuring cylinder containing the soil suspension and shake it vigorously end over end. Hydrometer analysis can be combined with the sieve analysis to determine the amounts (percents) of fines (silts and clays) in a sample. The hydrometer analysis doesnât require the soil to be passed through a series of sieves like in the sieve analysis. (3) Calculate the percent passing (or percent finer) by starting with 100 percent and subtracting the percent retained on each sieve as a cumulative procedure. NOTE 4: It is important to remove the hydrometer after each reading. 4.3 Sedimentation test with hydrometer. (Repeat 7.8 â 7.9 for each sample) 7.10 Record the hydrometer reading again after 6 hours, 52 minutes. This assignment helped me communicate effectively because I had to write a technical report including definitions, the history about hydrometers, equations, calculations, explanations, and answers to discussion questions.

This sample paper on Sieve Analysis Of Fine Aggregate Lab Report Conclusion offers a framework of relevant facts based on recent research in the field. The density of a soil-water suspension depends upon the concentration and specific gravity of the soil particles. 7. To perform the test, a hydrometer is placed in a container filled with a water and soil mixture and measurements are taken over time. Sieve analysis and hydrometer test lab report. Technical Report. For actual calculation purposes we al~o need to know the values of A given by Equation (5.3). The mechanical or sieve analysis is performed to determine the distribution of the coarser, larger-sized particles, and the hydrometer method is used to determine the distribution of the finer particles. Little or filter paper cage or sieve analysis lab report conclusion it is possible dry densities by calculation.
