Chapter 5, Problem 5.17QP
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
Mass of dry sand = 495.5 g
Calculate the specific gravity values (dry bulk, SSD, and apparent) and the absorption of the fine aggregate.
