Specific Gravity: "Specific Gravity is defined as the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water." The specific gravity is usually showed the strength and quality of the material. The specific gravity test is usually use to identification of stones or aggregates.Construction Aggregate Calculator - Vulcan Materials CompanyConstruction Aggregate Calculator.

The specific gravity of an aggregate is considered to be a measure of strength or quality of the material. Aggregates having low specific gravity are generally weaker than those with high specific gravity.Test Equipment for Determining Specific Gravity of AggregateSpecific Gravity and Fine Aggregate Kit, 230V 50/60Hz— H-3373A.4F 230V 50/60Hzl version of H-3373A Specific Gravity and Fine Aggregate Kit: Conical Mold and Tamper— H-3360 Used for determination of bulk and apparent specific gravity and absorption of fine aggregate, brass mold is 40mm ID at top, 90mm ID at bottom, 75mm high.Standard Test Method for Bulk Density ("Unit Weight") and ...1.1 This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.CHAPTER 3 - PHYSICAL PROPERTIES OF LIGHTWEIGHT .kg/m³), as well as aggregate that meets the requirements of ASTM C 330 and ASTM C 331. This chapter primarily addresses structural lightweight aggregates and does not include cellular or foam concrete, where lighter weight is developed primarily by inclusion of large amounts of air or gas through foaming-type agents. Requirements for structural

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft. Note, kg/cu.m divided by 16.02 = lbs/cu.ft ...Specific Gravity & Absorption of Coarse Aggregate Set ...Specific Gravity & Absorption of Coarse Aggregate set includes the SG-7A Wire Basket with handle and the SG-8 polyethylene 24qt Water Container for weighing coarse aggregate samples while suspended in water.

SCOPE AASHTO T 19 NOTE: 2 2.1.tamping rod to just penetrate the previous layer of the aggregate placed in the measure. 6.2. Determine the net mass of the aggregate in the measure to the nearest 0.1 lb (50 g). 6.3. Calculate the unit weight of the aggregate by multiplying the net mass of the aggregate by the factor found as described in Section 4 of this test method. 7.Fundamentals of ConcreteFor example, the specific gravity of a dry coarse aggregate (Gs) is 2.65. The unit weight of water is 62.4-lb/cu ft. The absolute volume of a 90-lb sample of the aggregate is: Absolute Volume = 90 lb / (2.65 x 62.4 lb/cu ft) = 0.544 cu ft.Density of Aggregate - Bulk and Relative Density - Civil ...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 .

The specific gravity of a blended aggregate is not simply the weighted average of the specific gravities of the individual components. To derive an appropriate equation, let's assume a blend of two aggregates (A and B). The weight of the blend is given by WWWblend A BDensity of Cement Sand and Aggregate | Cement Density ...The approximate apparent density of the aggregate that is commonly used in normal-weight concrete is between kg / m3 (75-110 lb / ft3).
