Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4°F (23°C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates.
Specific Gravity is defined as the ratio of Weight of Aggregate to the Weight of equal Volume of water. The specific gravity of an aggregate is considered to be a measure of strength or quality of the material.
Sep 25, 1970 · 2.2 Coarse Aggregate -- Aggregate most of which is retained on 4*75-mm IS Sieve and containing only so much finer material as is permitted for the various types described in this standard. NOTE -Coarse aggregate may be described as: a) uncrushcd gravel or stone which results from natural disintegration of
This procedure covers the determination of specific gravity and absorption of coarse aggregate in accordance with AASHTO T 85-10. Specific gravity may be expressed as bulk specific gravity (G. sb), bulk specific gravity, saturated surface dry (G. sb. SSD), or apparent specific gravity (G. sa). G. sb. and absorption are based on aggregate after ...
Water absorption, ideally, shouldn’t be more than 0.6%. Summing up, the specific gravity of coarse aggregates is indicative of its basic and fundamental quality. The specific gravity and porosity of aggregates greatly influence the strength and the water absorption capacity in concrete.
This test method determines the specific gravity and absorption of coarse aggregates through four determinations: bulk specific gravity, bulk saturated surface dry (SSD) specific gravity, apparent specific gravity, and percent absorption.
The document details an experiment to determine specific gravity and absorption values of various fine and coarse aggregates. Specific gravity values measured include bulk dry, apparent, and bulk saturated surface dry specific gravities.

the quality of aggregates used therein. The test methods given in this standard are intended to assist in assessing the quality of aggregates. In a given situation, for a particular aggregate, it may not be necessary to assess all the qualities and therefore it is necessary to determine before-
Apr 26, 2020 · Determine the specific gravity expressed as bulk specific gravity, bulk (saturated-surface-dry) specific gravity, as well as apparent specific gravity for three different samples of fine and coarse aggregates.
