Apparent Specific Gravity of Aggregates: It is calculated by measuring the weight of the oven-dry aggregate divided by its absolute volume excluding the natural voids in the aggregate particles. It is the realistic quantified data validated to use for the calculation of concrete mix proportioning.

The Fine Aggregate Test (ASTM C128 and AASHTO T 84) is a comparison of sample masses in oven-dry, saturated surface-dry (SSD), and immersed conditions. This test method offers alternate procedures to determine specific gravity. Either a volumetric flask or a simple pycnometer can be used for the gravimetric procedure. For the volumetric procedure, a special Le Chatelier flask is needed.

But sometimes it should take 23°C. This test is similar in nature to the coarse aggregate specific gravity test. How to Calculate Sand Specific Gravity? The fine aggregate specific gravity test measures its weight under three different sample conditions: Oven-dry (no water in the sample). Saturated surface dry (water fills the aggregate pores).

What is specific gravity and water absorption of fine aggregate, hi guys in this article know about what is specific gravity and water absorption of fine aggregate. as you know bulk density of fine aggregate coarse aggregate and cement and their specific gravity and water absorption capacity have an important role in designing of mix like M20 m25 M30 and so more—–.

Relative density (specific gravity) (SSD) is used in the determination of surface moisture on fine aggregate by displacement of water in Test Method C70. Relative density (specific gravity) (SSD) is used if the aggregate is in a saturated surface-dry condition, that is, if its absorption has been satisfied.

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. It is the measure of strength or quality of the specific material. Aggregates having low specific gravity are generally weaker than those with higher specific gravity values.
