46.5 kg (102.3 lb) of fine aggregate is mixed with 72.3 kg (159.1 lb) of coarse aggregate. The fine aggregate has a moisture content of 2.0% and absorption of 3.4%, whereas the coarse aggregate has a moisture content of 1.3% and absorption of 3.8%. What is the amount of water required to increase the moisture contents of both fine and coarse aggregates to reach absorption? Why is it important to determine the amount of water required to increase the moisture content of aggregate to reach absorption? Use one system of units only as specified by the instructor. Problem 8 - 9. 5.16 Students in the materials lab performed the specific gravity and absorption test (ASTM C127) on coarse aggregate and they obtained following data: 3862.1 g Dry weight SSD weight = 3923.4 g Submerged weight 2452.1 g Calculate the specific gravity values (dry bulk, SSD, and apparent) and the absorption of the coarse aggregate. = 5.17 The specific gravity and absorption test (ASTM C128) was performed on fine aggregate and the following data were obtained: Mass of SSD sand = 500.0 g Mass of pycnometer with water only = 623.0 g Mass of pycnometer with sand and water = 938.2 g 495.5 g Mass of dry sand = Calculate the specific gravity values (dry bulk, SSD, and apparent) and the absorntion of the fine aggregate 46.5 kg (102.3 lb) of fine aggregate is mixed with 72.3 kg (159.1 lb) of coarse aggregate.
