Specific gravity of coarse aggregates: its importance. the specific gravity of aggregates normally ranges from about 2.5 to 3.0. according to ‘ a. m. neville ’ (author of the properties of concrete), the majority of natural aggregates have a specific gravity of between 2.6 and 2.7.
The fine aggregate specific gravity test (figure 1) is used to calculate the specific gravity of a fine aggregate sample by determining the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. it is similar in nature to the coarse aggregate specific gravity test.
The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates. in normal concrete the aggregate weighs 1,520 – 1,680 kg/m 3 , but occasionally designs require either lightweight or heavyweight concrete.
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.
Fine aggregate consisting of natural or manufactured sand including high-density minerals. coarse aggregate may consist of crushed ore, crushed stone, or synthetic products, or combinations or mixture thereof. aggregates shall meet the required uniformity of specific gravity and fixed water content.
Calculate the void content in the aggregate using the bulk density determined by either the rodding, jigging, or shoveling procedure, as follows: %voids= 100[(sxw)-m]/ (sxw) equation 6. where: m: bulk density of the aggregate, kg/m^3, s: bulk specific gravity . w: density of water, 998 kg/m^3. read more:

Specific gravity of soil is a very important parameter which is used to determine particle size and void ratio. the usual values of specific gravity of soils lie in between (2.65-2.80). this is a …
Relative density can be calculated by simply multiplying the specific gravity of the coarse aggregate, whose typical range is 2.4 to 2.9 and the density of water.
Aggregate. various tests, including quality, freeze-thaw, and alkali-silica reactivity (asr) are performed on aggregates used for road and bridge construction in illinois. these tests quantify the physical characteristics of each aggregate product from each source.
Feb 15, 2019 the concrete density is greatly depending on the specific gravity. a porous nature (i.e. those which increase in weight exceeding 10% of dry weight after immersion for 24 hours) should not be permitted, unless specified. the range of specific gravity for aggregates should be between 2.4 and 2.9. soundness of aggregate

Aggregates generally occupy 70 to 80% of the volume of concrete and therefore have a significant effect on its properties. strength of concrete and mix design are independent of the composition of aggregate, but durability may be affected. aggregates are classified based on specific gravity as heavyweight, normal-weight, and lightweight.
