Specific gravity is easily calculated by determining the densities by the displacement of water All aggregates contain some porosity and the specific gravity value depends on whether these pores are included in the measurement There are two terms that are used to distinguish this measurement absolute specific gravity and bulk specific gravity

in aggregate by washing Procedure A shall be used unless otherwise specified When accurate determinations of material finer than the No 200 in fine or coarse aggregate are desired this test method is used on the aggregate sample prior to dry sieving according to ND T 27 The results of this procedure are included in the calculations for ND

Whereas bulk specific gravity (BSG) is a measure of the weight/volume of solids and pores of a material ASG BSGSSD BSGOD However since the porosity of most rocks used in concrete is 1 to 2% the values of all specific gravities are approximately the same in the range of 2 5 to 2 8 Unit Weight

Overview The Los Angeles (L A ) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing degradation and disintegration in order to produce a high quality HMA Figure 1 L A abrasion testing equipment

FA used in the present research are included in table 1 For all mixtures well graded sand finer than 2 36 mm was used Normal natural course aggregate that is a crushed stone of maximum nominal size 20 mm and 10 mm was selected as coarse aggregate Course aggregate passing through 20 mm 12 5 mm

Properties of concrete aggregates

Typically coarse aggregate sizes are larger than 4 75 mm (5 mm in British code) while fine aggregates form the portion below 4 75 mm A maximum size up to 40 mm is used for coarse aggregate in most structural applications while for mass concreting purposes such as dams sizes up to 150 mm may be used
