7. The following table shows a data set from a sieve analysis. (a) Plot the grain size distribution curve. (b) Compute Cu and Ce. (c) Report the percentage gravel, sand, silt, and clay according to AASHTO. US Sieve No. Opening (mm) Weight Retained (gî) 4 4.75 15.6 10 2.0 35.4 20 0.85 121.8 40 0.425 102.3 60 0.25 82.8 100 0.15 50.4 140 0.106 37.8 200 0.075 30.6 Pan 56.7

A 627-g sample of sand was found to have the following amounts of material retained on each sieve/pan: 3/8 in. = 22 g, No. 4 = 45 g, No. 8 = 96 g, No. 16 = 122 g, No. 30 = 163 g. No. 50 86 g, No. 100 = 51 g, No. 200 = 30 g, pan = 11 g a. Calculate the fineness modulus of the sand. b. Is this sieve analysis valid for acceptance purposes? Explain why. c. Does the sand meet the particle size criteria of ASTM C 33. Fully justify your answer (list and check all relevant criteria from ASTM C33)

Kindly answer all of the questions in this problem. Thank you so much.

As part of a quality controlprogram, the field inspection engineer conducted a sand cone test to determine the field density. The following data were recorded using the sand cone method. • Calibrated dry density of Ottawa sand = 1667 ??/?3• Mass of Ottawa sand to fill the cone = 0.117 kg• Mass of jar + cone + sand (before use) = 6.1 kg• Mass of jar + cone + sand (after use) = 2.83 kg• Mass of moist soil from hole = 3.35 kg• Moisture content of moist soil = 16.1%a. Determine the dry unit weight of compaction in the field. (ANS: 14.97kn/m3)   PLS ANSWER NUMBER 2 WITH COMPLETE SOLUTION 2. What is the relative compaction in the field if the maximum dry unit weight in the laboratory is 15.93 ??/?3?

The coefficient of permeability (K value) of a soil describes how easily a liquid will move through a soil. True )False Permeability measurement is used to: calculation of seepage through earth dams calculation of seepage under sheet pile walls estimating the seepage rate from waste storage O all of the answers are correct Which state describes soil that does not show cracks when deformed (choose correct state that applies). A) Plastic state B) Liquid State C) Semisolid state D) Solid state

If after completing a Sieve Analysis lab, I notice that the stack of sieves was not arranged in the order of progressively smaller openings from top to bottom. I noticed that two sieves in the middle of the stack had their order reversed; the sieve with a tinier opening was on top of a sieve with a larger opening. How will this mistake affect my results and can my results still be used for obtaining the soil’s grain-size distribution curve? Please help me in figuring this out, I believe that it will affect the soil’s grain-size distribution curve's accuracy, but I am not sure why or in what capacity.

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

From the results of a sieve analysis, shown below, determine: (a) the percent finer than each sieve (prepare table) and plot a grain-size distribution curve (use the gradation curve, template   (b) D10, D30, D60 from the grain-size distribution curve, (c) the uniformity coefficient, Cu, and (d) the coefficient of gradation, Cc.
