After conducting a field density test in Road Lot 1 and 2, the results of Sand Cone Method (Ysand = 16.353 kN/m³) are as follows: Location Total Weight of Retained Mass Sand (kg) 7.40 7.40 Moisture Content (%) Weight of Soil Sample _(kg) 1.39 of Sand (kg) 6.2 Road Lot 1 20% Road Lot 2 6.3 19% 1.30 Properties of Soil base on Soil Investigation Result: Specific gravity of Soil Particles - 2.75 Weight of Soil Sammple 1.6309 kg Volume of Soil Sample - 0.0009 cu.m. Determine the following: a. Maximum dry unit weight (kn/m^3) of soil sample if optimum moisture content is 22% b. As Civil Engineer, will you allow concrete pouring in Road Lot 1 base on FDT result? (Relative compaction should be equal or higher than 95%) c. As Civil Engineer, will you allow concrete pouring in Road Lot 2 base on FDT result? (Relative compaction should be equal or higher than 95%)

Please answer the following questions. In solving the problems, you should use stored values to get the exact values.
Pampanga sand with Gs =2.41 is mixed 16% by weight of water and compacted to produce a cylindrical sample of 50 mm diameter and 100 mm long with 2% air porosity. Calculate the void ratio of the sample.
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
Note) For soil sample in Table 2, initial thickness of sample = 14.31 mm, sample area = 2827.433 mm^2, dry weight measured at the end of test = 52.53 g, specific gravity = 2.7 Also, Determine the compression index and expansion index Please show graph
