Sep 19, 2019 As per the definition given in the ‘IS: 2386 (Part III) 1963’, (Indian Standard- Methods of Test for Aggregates for Concrete Specific Gravity, Density, Voids, Absorption and Bulking), the specific gravity of coarse aggregates is the weight of the aggregates dried to constant weight in an oven at 100°C divided by its absolute volume including the natural voids within the aggregate

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.

The aggregate is placed in a shallow tray and heated to about 110 0 C in the oven for 24 hours. Later, it is cooled in an airtight container and weighed. Procedure for Specific Gravity determination of Aggregate finer than 6.3mm. A clean, dry pycnometer is taken and its empty weight is determined.

Specific gravity and Water Absorption Test of Aggregates major important tests to be performed on aggregate. These two parameters or property of aggregate play an important role in the mix design of concrete.As we know that aggregate occupies 70 to 80% volume of concrete, its testing becomes essential before use.

Specific Gravity Test Procedure for Fine Aggregate Sand. The Steps should follow be followed for determination: Calibrate the pycnometer. Weigh a clean, dry pycnometer to the nearest 0.01 gram. Fill the pycnometer with room-temperature distilled water. Ensure that the bottom of the meniscus is even with the calibration mark.

Jan 11, 2017 The specific gravity of aggregates usually applied in construction of roads varies from about 2.5 to 3.0 with a standard of about 2.68. Although high specific gravity is normally taken as a signal of high strength and quality, it is not wise to determine the appropriateness of a example road aggregate exclusive of discovering the mechanical

5.1 Density and specific gravity are cornerstone terms that help define many useful properties of wood and wood-based materials. These terms designate concepts that have distinct definitions though they relate to the same characteristic (mass in a unit volume). Generally, in the US and Canada, density of wood is measured in terms of specific gravity, or relative density.

5.2 Relative density is used to calculate the volume occupied by the aggregate in various mixtures containing aggregate, including hydraulic cement concrete, bituminous concrete, and other mixtures that are proportioned or analyzed on an absolute volume basis. Relative density (specific gravity) is also used in the computation of voids in aggregate in Test Method C29/C29M.
