SPECIFIC GRAVITY OF COARSE AGGREGATE AASHTO T 85. 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 °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 are porous, and posses a number of voids, some of which are penetrable and some impenetrable. This nature of aggregate makes it difficult to describe one value for its specific gravity. Based on the test methods used, three types of specific gravity are calculated – Bulk, Saturated surface dry, and Apparent.
Normal weight aggregate produces concrete with unit weight ranging from 23 to 26 KN/m3 with a specific gravity between and The crushing strength at 28 days of these aggregates ranges between 15 to 40 MPa.
For aggregates, density is determined by multiplying the relative density (specific gravity) of the aggregate times the density of water. Bulk Density of Aggregate [1] The bulk density or unit weight of an aggregate is the mass or weight of the aggregate that required to fill a .

· The specific gravity of aggregates generally ranges between For recycled aggregates the specific gravity may be less than Lesser specific gravity indies the low strength (weaker aggregates) and more porosity. Higher specific gravity indies more strength of aggregates and less porosity (which increases the durability of ...
Its specific gravity was having initial and final setting times of 70 minutes and 480 minutes, respectively. For fine aggregate, natural sand was used, having a maximum size of mm. Its specific gravity was, conforming to ZoneIII, and having a fineness modulus of
Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately. That portion of an aggregate passing the mm (No. 4)
AASHTO T 85 Specific Gravity and Absorption of Coarse Aggregate ASTM C127 Standard Test Method for Density, Relative Density (Specific Gravity), and Absorption of Coarse Aggregate 3. DEFINITION Coarse aggregate: For the purpose of this test, coarse aggregate is all aggregate material retained on the mm sieve.
Apparent specific gravity is intended to only measure the specific gravity of the solid volume, therefore it will be the highest of the aggregate specific gravities. It is formally defined as the ratio of the mass of a unit volume of the impermeable portion of aggregate (does not include the permeable pores in aggregate) to the mass of an equal volume of gasfree distilled water at the stated ...

The specific gravity of most of the natural aggregates ranges from – It may be below this range in the case of lightweight aggregates. Specific gravity can be used to determine the suitability and quantity of the aggregates for the given volume of concrete. Generally, aggregates with a higher value of specific gravity are compact ...
Bulk specific gravity of aggregate (Gbam) Since the aggregate mixture consists of different fractions of coarse aggregate, fine aggregate, and mineral filler with different specific gravities, the bulk specific gravity of the total aggregate in the paving mixture is given as bmf mf bfa fa bca ca ca fa mf bam G P G P G P P P P G ...
Absolute specific gravity (ASG) refers to the solid material excluding the pores, and bulk specific gravity (BSG), sometimes called apparent specific gravity, includes the volume of the pores. For the purpose of mixture proportioning, it is important to know the space occupied by the aggregate particles, including the pores within the particles.
· Water Absorption and Specific Gravity of Aggregate < 10 mm _ test Procedure Pycnometer Method Sample size: Kg – for Aggregates to 10 mm and ). Kg – for aggregates finer than mm. Put the sample for 24 hours in water at 22 to 32 degree C temperature. The sample is taken out and drained and is put to SSD conditions and weighed.

The objective of this paper is to determine the specific gravity and absorption of coarse aggregates using a new proposed approach utilizing vacuum saturation. In lieu of the conventional soaking period of 24 ± 4 h, this proposed research approach employs the use of 10, 20 and 30 min of vacuum saturation at 30 mm Hg ( kPa) pressure.
