Please understand question properly and answer correctly.... Question: You suspect that a fine-grained soil sample contains kaolinite, illite, and smectite minerals. Describe in logical sequence the tests you would do to verify that these clay minerals are present. Indicate the reasons why you choose these tests and the criteria for distinguishing among the minerals

The properties of seven different clayey soils are shown below. Investigate the relationship between the strength and plasticity characteristics by performing the following tasks: Soil Beauharnois Detroit I Horten Gosport Mexico City Shellhaven St. Thuribe Mineral % Clay fraction (<2 μm) Kaolinite Illite 79 36 40 55 90 41 36 Montmorillonite Halloysite (hydrated) Halloysite (dehydrated) Attapulgite Allophane Activity, A 0.52 0.36 0.42 0.89 4.5 1.33 0.33 Liquid limit, LL 35-100 60-120 100-900 Undisturbed shear strength (kN/m²) 50-70 40-55 150-250 200-250 18 17 41 29 46 36 38 a.

The particle size analyses for four clay soils particles conducted ingeotechnic laboratory are shown in Table Q1(a)(i) and Table Q1(a)(ii).Using to the American Society for Testing and Materials (ASTM) methodanalysis; (i) With the plot of graph, find the value of Cu and Cz for all types ofsoil (i) With the plot of graph, find the value of Cu and Cz for all types ofsoil

In a sieve analysis test, 95.5% of the sample is passing the 5mm sieve and 5.13% is passing sieve #200, which of the following is correct about this sample: O There is no clay in the sample ) the percent of silt and clay is: 5.13% There is 4.5% Sand and Gravel in the sample O 95.5% of the sample is Sand and Silt O O

The dry unit weight of a sand sample in the loosest state is 13.34 kN and in the densest state, it is 21.19 kN. Its grain specific gravity is 270 and has a porosity of 33% P.S. Sorry for the question can’t fully grasp what was written

Discuss your results and compare your results with any published data. For the bulk density test, obtain the value of dry density. How does the values of (i) void ratio (ii) porosity influenced your results? How will these values differ if the soil is fully saturated, partially saturated or submerged? Support your assertions using relevant phase relationship equations. Whatwill happen to the values of particle density (specific gravity) obtained if the soil sample contain large quantities of peat or organic material? How will the results be used in specific practical conditions in the construction industry? Explain any source(s) of error in your experiment and state how it affected your result.

The identification of clay minerals requires special techniques and equipment and trained personnel. Explain different techniques and equipment’s are there for identification.
