surfacedry basis is used if the aggregate is wet, that is, if its absorption has been satisfied. Conversely, the bulk specific gravity determined on the ovendry basis is used for computations when the aggregate is dry or assumed to be dry. Apparent specific gravity pertains to the relative density of the solid material making up the

· Specific gravity of coarse aggregates is measured at the bulk dry, saturatedsurface dry and apparent conditions. The Gsb (dry) is the specific gravity when water is considered to have penetrated all the effective voids in the coarse aggregate while the apparent specific gravity (Gsa) determines the specific gravity without factoring any penetration of .
coarse aggregate. The specific gravity may be expressed as bulk oven dry (OD) specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. The bulk (SSD) specific gravity and absorption are based on aggregate after 15 to 19 hours soaking in water. This method is not intended to
The volume of coarse aggregate would be Coarse Aggregate = 1674 lb/(( + ) à pcf) = ft3 The volume of fine aggregate would be ( + + + ) = ft3 When the specific gravity of the fine aggregate was changed by the withinlab D2S, the batch weight of fine aggregate would be cu. ft à ( = ) à pcf = 1266 lb (an .
· The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity. This property helps in a general identifiion of aggregates. The specific gravity of aggregates normally used in construction ranges from about to .

For example, the specific gravity of a dry coarse aggregate (Gs) is The unit BULK SPECIFIC GRAVITY (Gs) The bulk specific gravity of a material is the ratio volume of the container to yield the dry rodded unit weight in terms of weight per volume modulus of the fine aggregate should range from to . From these values calculate the (cumulative) percentage of material that would .

· Aggregate specific gravity is needed to determine weighttovolume relationships and to calculate various volumerelated quantities such as voids in mineral aggregate (VMA), and voids filled by asphalt (VFA). AASHTO T 85 and ASTM C 127: Specific Gravity and Absorption of Coarse Aggregate.
Where: G = Specific gravity of the combined aggregate. P 1,P 2,P 3, etc. = Percentage by weight of aggregates No. 1,2,3, etc. in the mixture. G 1,G 2,G 3, etc. = Specific gravity (BulkSaturated Surface Dry) of aggregates No. 1,2,3, etc. Example: % in Mix Specific Aggregate by Weight Gravity Crushed Stone 45 Sand 40 Mineral Filler 15 G = 100 = .
specific gravity, bulk saturated surface dry (SSD) specific gravity, or apparent specific gravity. The bulk (SSD) specific gravity and absorption are based on aggregate after 15 to 19 hours soaking in water. This method is not intended to be used with lightweight aggregate. The specific gravity and absorption of coarse aggregate is normally

Procedure for Specific Gravity determination of Aggregate finer than A clean, dry pycnometer is taken and its empty weight is determined. About 1000g of clean sample is taken into the pycnometer, and it is weighed. Water at 27 0 C is filled up in the pycnometer with aggregate sample, to just immerse sample. Immediately after immersion the entrapped air is .
· The specific gravity most frequently required and easily determined, known as ''gross apparent specific gravity'', is based on the saturated and surfacedry condition of the aggregate because the water absorbed in the pores of the aggregate does not take part in the chemical reaction of the cement and can, therefore, be considered as a part of the aggregate. .
Specific Gravity and Water Absorption Test Aggregates The surface dried aggregate is then weighed =W3 g (vi) The aggregate is now kept in a hollow tray and put in an oven whose temperature is maintained at 110° C for 24 hrs It is then detached from the oven, let chilled in an air tight vessel and weighted=W4 g (1) Specific gravity = (dry weight of the aggregate .
