If your teacher is asking you to write a lab report, it’s an excellent concept to read over this page, too. Representative sample was chosen by quartering (according to BS 812: Part 102: 1984) or by use of a sample splitter (Fig. It assumes that dispersed soil particles of various shapes and sizes fall in water under their own weight as non-interacting spheres. The hydrometer analysis is anchored on Stoke’s Law, which states that the particle size is directly proportional to the settling velocity in a fluid. Test Procedure The hydrometer test is performed by testing a soil sample that was allowed to pass through a … Standard sieves for grading coarse aggregates- 1 ½ in., 1 in., ¾ in., ½ , 3/8 in., 4 in, plus a 4.75 mm(#4 sieve) The larger the particle, the quicker it will fall out of sedimentation. No Digital File | -10 | | Thus, this entails the acquisition of the percentage of particles of a certain equivalent particle diameter was calculated. For analysis of more silt and clay size fractions (i.e., 50–20, 20–10, 10–5, 5–2, 2–1, <1μ), this study showed no difference between the two methods.  It consists of four major components: air, water, organic matter, and mineral matter. The samples was dried to constant weight in the furnace at a temperature of 105° ±5° C. The density of a soil-water suspension depends upon the concentration and specific gravity of the soil particles. For this experiment, about 500 grams of fine aggregate was weighed. 2:Read the temperature of the liquid by the thermometer Tactual . SUMMARY OF METHOD .................................................................................................3 Materials and Method: ANALYSIS OF GRANULAR SOIL MATERIALS 200 sieve). Save my name, email, and website in this browser for the next time I comment. This experiment involves the hydrometer analysis of fine soil which passes through the No. What do I do now I’ve written my laboratory report? Procedure | 1.0 | | (79.4kg) Set includes: (1) H-4239 Hydrometer Jar Bath (6) H-4244 Hydrometer Jars (1) H-4241 Soil Hydrometer A (1) H-4242 Soil Hydrometer B (1) H-4260 Soil Dispersion Mixer (1) H-4247 Sodium Hexametaphosphate, 1 lb. A lab report is generally utilized for interacting the findings of laboratory studies. Hydrometer Analysis Set Determines the distribution of soil particles smaller than No. The hydrometer test is a grain size distribution test used to characterize fine-grained soils. Date Assigned: 10/17/2011 The analysis measures the rate of sedimentation. TEST METHOD FOR THE GRAIN-SIZE ANALYSIS OF GRANULAR MATERIALS SO-Sieve – Sieve Analysis, Hydrometer And Atterberg Limits … – Hydrometer Test For Soil Lab Report. Hydrometer Analysis: (1) Take the fine soil from the bottom pan of the sieve set, place it into a beaker, and add 125 mL of the dispersing agent (sodium hexametaphosphate (40 g/L)) solution. 2. Written by: Jon Leyba It ought to also be complete and helpful.  Clay is any soil particle below 0.002 millimeters, including colloidal clay so small it does not settle out of suspension in water. SA-1 Soil Hydrometer, ASTM 151H is graduated to read specific gravity. Another thing is to ensure that the language used is accurate, accurate and proper. The procedure used followed ASTM standard D422, Standard Test Method for Particle-Size Analysis of Soils. Dry sieve analysis will allow for the separation of grain sizes between 4.0Φ at the smallest and -4.0Φ at the largest, the pipette method and the laser granulometer methods will allow for the analysis and sorting of the pan fractions of the dry sieve experiments, between 5.0Φ-10.0Φ, and therefore provide a precise representation of the distribution of grain sizes at the field sites. Equipment | 1.0 | | It has a range of 0.995—1.038 in 0.001 divisions at 68°F (20°C). Data Sheet | 1.0 | | ...Title Page / Objective | 0.5 | | Here are some of the subjects to look for on the cover of a laboratory report: What are the other pages in laboratory report sample? Plain form hydrometer has an approximate length of 280 mm. APRIL 2007  Silt is any soil particle from 0.002 - 0.06 millimeters. Page 1 of 13 Particle Size Distribution Please join StudyMode to read the full document. 4. Lab Report Sample is frequently followed by a last paragraph. During the actual sedimentation test, the readings should be taken at the bottom of the meniscus but since the soil … The hydrometer analysis doesn’t require the soil to be passed through a series of sieves like in the sieve analysis. Because the dispersion mixture increases the specific gravity of the resulting liquid, a composite correction for the hydrometer reading must be applied. EB 07-039 Analysis The sediment to be analyzed is thoroughly dispersed in 1000ml solution of distilled water and dispersing agent. Introduction | 1.5 | | At about the same time as each soil suspension hydrometer reading, take a hydrometer The method is based on Stoke’s law governing the rate of sedimentation of particles suspended in water. Oven-dry wt. 4. Van Joseph E. Casalme 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 samples for the experiments in this lab report were collected from fieldwork conducted at Clarach,... StudyMode - Premium and Free Essays, Term Papers & Book Notes. viscosity must be known. The hydrometer analysis is a process of grain size determination that usually takes 78 hours. more ». The analysis measures the rate of sedimentation. Mechanical Analysis of Soil 2C1-2). Mechanical Analysis of Soil A standard test method for soil particle analysis was carried out for the ASTM Standard D422 hydrometeorological test. Fine Aggregate  There are two methods generally used to find the particle– size distribution of soil: They are utilized to sum up and translate the information collected. For example, if the trainee’s instructor needs him or her to compose a thesis statement (a research study paper), you can put that here. This includes the basic details about the experiment, such as the name of the experiment, the name of the scientist carrying out the experiment, the name of the group doing the experiment, the name of the chemical compound that is being tested, and the date of the experiment. The hydrometer analysis is used to determine the specific gravity of density of the suspension. 5. The dispersing agent, such as sodium Hydrometer analysis can be combined with the sieve analysis to determine the amounts (percents) of fines (silts and clays) in a sample. the soil. The following steps were used for the hydrometric test: the method of testing and discussing the analysis of soil particulate matter by hydrometer... revision of #2 For fine aggregate, standard sieve size of 10 mm, 5.00 mm, 2.36 mm, 1.18 mm, 600m, 300 m and 150 m (Fig. Naturally. 200 sieve size (.075 mm). Finally, ensure that you check the scientific precision prior to publishing or sending the paper for publication. The sample to be tested should be the approximate weight desired when dry. Introduction:  The structure of soil determines its suitability for concrete, road subsurface, building foundation, or filter media. Shipping wt. Objective: Stir the mixture until the soil is thoroughly wet. The hydrometer analysis is an application of Stokes’ 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.
