And percentage of voids present in fine aggregate is calculated with the help of specific gravity of fine aggregate and their Loose bulk density by the following formula. % of voids = { (Gs _R)/Gs}×100. Where Gs = specific gravity of fine aggregate and their value is 2.62. R = loose bulk density of fine aggregate = 1.398 kg/L.

The bulk density of crushed sand is 1.75 g/cm 3. The basic gravity of the crushed sand is 2.5 to 2.9 which varies on the parent rock. There is no need to correct bulking during the mixing design by using Crushed Sand in concrete. Ability of old surface moisture Crushed sand is up to 10%. It has less adulteration than the sand of the river

the oven-dry specific gravity may be directly computed. This representative coarse lightweight aggregate with a measured dry loose bulk unit weight of 714 kg/m3 ( 44.6 pcf) and com puted oven-dry specific gravity of 1.38 results in the aggregate particle occupying 52 percent of the total bulk volume, with

Clearly, the definition also covers a vast range of materials. The lightest manufactured aggregates have a loose bulk density below 60 kg/m 3, though a range of 400–1150 kg/m 3 is more typical for use in concrete. Table 15.1 gives a classification based upon the raw material source and loose bulk density.

For this, 30 samples of crushed sand were procured from different sources. In addition, few alternative sands were also considered for the analysis which included copper slag, Ennore sand and two types of cinders. The parameters tested are flow time based on New Zealand flow cone, loose bulk density, uncompacted voids and specific gravity.

The loose bulk density and water absorption varied between 765 and 936 kg/m 3 and 1–34%, respectively. The density of the concrete produced using sintered fly ash aggregates varied from 1650 to 2010 kg/m 3. Also from the studies, it is found that the compressive strength is between 24 and 74 MPa.

But when the sand is in wet condition then water is presented in the sand particles and changes the quantity by volume. In wet condition, the volume of the sand density is increased. In a different state the average density of sand are: Loose sand density: 1442 kg/m 3. Dry sand density: 1602 kg/m 3. Packed sand density: 1682 kg/m 3.
