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
