C 128-88 SCOPE 11 This method covers the determination of bulk and apparent specific gravity 2323C734734F and absorption of fine aggregate. 1The specific gravity of aggregates normally used in construction ranges from about 25 to 30 with an average value of about 268. 2Specific gravity of aggregates is considered as an indication of strength.
Material having higher Specific Gravity is generally considered as having higher strength. Water absorption of aggregate is a measure of porosity. 51 Relative density specific gravity is the ratio of mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles also referred to as the absolute volume of the aggregate.
It is also expressed as the ratio of the density of the aggregate. Reading time. 1 minuteContentsProperties of Aggregates and its Values for use in Construction1.

Specific Gravity Relative Density. Is the ratio of the mass of an aggregate to the mass of a volume of water equal to the volume of the aggregate particles. Specific gravity is a fundamental property of aggregates that are used in many different calculations and.
Specific Gravity the ratio of the mass in air of a volume of a material to the mass of the same volume of gas-free distilled water at a stated temperature. Apparent Specific Gravity Gsa the ratio of the mass in air of a volume of the impermeable portion of aggregate to the mass of an equal volume of gas-free distilled water at a stated temperature. Bulk Specific Gravity Gsb the ratio of the mass in air of a volume of aggregate.
As preconized by Siddique 2010b the bulk specific gravity values of the MSWI ash ranges from 15 to 22 for the sand-size or fine particles and 19 and 24 for the coarse particles compared to approximately 2628 for conventional aggregate materials. Specific gravity the bulk specific gravity on the basis of weight of saturated surface-dry aggregate and the absorption as defined in AASHTO M 132. 13 The values stated i n SI units are to be regarded as the standard.

Neville Author of the Properties of Concrete the majority of natural aggregates have a specific gravity of between 26 and 27. However high specific gravity is considered as an indication of high strength. Learn to find Specific gravity of Fine Aggregates with detailed procedure tabulation columnTHEORY.
Aggregates are divided into two categories based on cons. The relative density specific gravity of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density Mass of the Aggregate Mass of equal volume of water.
Most aggregates have a relative density between 24-29 with a corresponding particle mass density of 2400-2900 kgm 3 150-181 lbft 3.
