What is Specific Gravity and Water Absorption of Aggregates about?

This document describes an experiment to determine the specific gravity and water absorption of aggregates. It defines bulk specific gravity, bulk SSD specific gravity, and apparent specific gravity. The procedure involves weighing aggregates dry, saturated surface dry (SSD), and submerged to calculate these values. For fine aggregates, about 250g are soaked, weighed SSD, and tested in a pycnometer. For coarse aggregates over 4.75mm, about 1000g are soaked, weighed SSD in air and water, then dried and weigh
