A saturated aggregate sample with an absolute volume of 5.05x10^-5 m^3 has a mass of 178 g before drying and 139 g after drying in an oven. Assume the water absorption by volume to be 59.18%. Determine the following: a. Specific gravity of the solid particles b. Mass specific gravity c. Void Ratio d. Porosity
TEST PROCEDURE: 1. Dry the aggregate test sample to a constant weight at a temperature of 110 ± 5°C, then cool to room temperature. 2. Select suitable sieve sizes to furnish the information required by the specifications covering the material to be tested. Common sieves in millimeters are 37.5, 25, 19, 12.5, 9.5, 4.75, 2.36, 1.18, 0.6, 0.3, 0.15, and 0.075 mm (11 2 in., 1 in., 3 4 in., 1 2 in., 3 8 in., No. 4, No. 8, No. 16, No. 30, No. 50, No. 100, and No. 200). 3. Nest the sieves in order of decreasing size of opening, and place the aggregate sample on the top sieve. 4. Agitate the sieves by hand or by mechanical apparatus for a sufficient period. The criterion for sieving time is that, after completion, not more than 1% of the residue on any individual sieve will pass that sieve during 1 minute of continuous hand sieving. 5. Determine the weight of each size increment. 6. The total weight of the material after sieving should be compared with the original weight of the sample placed…
