500 gm oven dry fine aggregate was tested to find its physical properties. The output from the test was as follows: SSD = 510 gm, mass of the vessel full of water = 1200 gm, mass of vessel plus sand and topped up with water= 1500 gm, mass in wet condition 518 gm, Apparent specific gravity= 2.5 . The grading of the fine aggregate is in the table below. Answer the followings: 1-Moisture content % is 2- The mass of oven dried sand is
A sample of lightweight coarse aggregate weighs 532.3 g when oven-dried, 615.7 g when saturated surface-dried, and 191.3 g when submerged. Calculate the bulk specific gravity, apparent specific gravity, and percent absorption.
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…
