In an ongoing land development project, a Contractor requested for a concrete pouring request. 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: Total Weight of Retained Mass Sand Weight of Soil Sample (kg) 1.39 Location Moisture of Sand Content (%) (kg) 7.40 (kg) 6.2 Road Lot 1 20% Road Lot 2 7.40 6.3 19% 1.30 Properties of Soil base on Soil Investigation Result: Weight of Soil Sammple - 1.631 kg Volume of Soil Sample – 0.0008 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%)
