Bulk density of coarse aggregate procedure

METHOD B9 THE DETERMINATION OF THE BULK DENSITY OF COARSE AND FINE AGGREGATE SCOPE The bulk compacted and uncompacted density of an aggregate as defined below is calculated from the mass of compacted or uncompacted aggregate that fills a measure of known volume. Definition The bulk density of an aggregate is the mass of

ar However, as the void content in aggregate is calculated from bulk density and bulk specific gravity, the precision of the nd voids content reflects the precision of these measured param- 15.2 Coarse Aggregate (bulk density): eters given in 15.2 and 15.3 of this test method and in Test 15.2.1 Single-Operator Precision—The single-operator

Jan 03, 2021 Bulk density of aggregates is the mass of aggregates required to fill the container of a unit volume after aggregates are batched based on volume. It depends on the packing of aggregate i.e. Either loosely packed aggregates or well dense compacted aggregates. In case, if the specific gravity of a material is known, then it

Raj et al. (2014) found the optimum bulk density at proportion of 42% coarse aggregate of 20 mm down size, 18% coarse aggregate 12.5 mm down size

Jun 11, 2021 Procedure: The following procedures is adopted which vary with the type of soil sample. Sample (Coarse): The vacant container is weighed attributed with W 1. The sample is taken roughly half of same container and its mass is determined later attributed by W 2. Now fill up the bottle with water until the coarse aggregates level

5.4.1 Determine the density of the coarse aggregate extracted from the RAP using duplicate samples. Calculate the density of the coarse aggregate in the asphalt mixture by using a calculation based on the density of the virgin coarse aggregate determined following 5.1 or 5.2 and the density of the RAP coarse aggregate

This test method determines the specific gravity of coarse aggregates that have been soaked for a period of 15 hours (Figure 1). There are four determinations that may be made from this procedure. They are as follows: Figure 1 Coarse Aggregate Gravity Apparatus A. Bulk Specific Gravity (Gsb) (also known as Bulk Dry Specific Gravity)

Jan 13, 2021 Bulk Density and Voids in Aggregate asper IS: 2386-3 (1963) Hi friends, you are welcomed in the world of Civil Allied Gyan. “Read here definition, apparatus, IS code, test procedure, formula, result and lab report for bulk density and voids in aggregate as per IS: 2386-3 (1963).”. Important:-This method of test covers the procedure for determining unit

This test method is used to determine the bulk density of the given fine grained specimen. During the concrete mix design, when the aggregate is to be batched by volume or by weight, then it becomes necessary to know the mass of the aggregates that will fill the container of unit volume. If we know the bulk density of the aggregate material

Jul 16, 2017 For this test procedure, it is sufficiently accurate to accept the density of water at room temperature to be 998 kg/m 3. Rodding the aggregates: Fill the bucket one third full and rod the aggregate layer with 25 strokes of the tamping rod, evenly distributed over the surface

Further, aggregates in hauling units and stockpiles usually contain absorbed and surface moisture (the latter affecting bulking), while this test method determines the bulk density on a dry basis. A procedure is included for computing the percentage of voids between the aggregate particles based on the bulk density determined by this method

This Standard sets out the method for determining the bulk density of fine, coarse, or mixed aggregates. The bulk density is determined in the uncompacted, compacted, or uncompacted and compacted states. The test is normally performed on material dried to constant mass, but may be performed at other moisture conditions if specifically required

IN-PLACE DENSITY T85_short_10.docx E&B/ID 16-1 Pub. October 2012 SPECIFIC GRAVITY AND ABSORPTION OF COARSE AGGREGATE FOP FOR AASHTO T 85 Scope This procedure covers the determination of specific gravity and absorption of coarse aggregate in accordance with AASHTO T 85-10. Specific gravity may be expressed as bulk

Feb 15, 2022 This method is based on determining the coarse aggregate content, dry rodded coarse aggregate bulk density, and fineness modulus of sand. Thus, this method takes into account the actual voids in compacted coarse aggregates

Where Gs = specific gravity of coarse aggregate and their value is 2.65. R = loose bulk density of coarse aggregate = 1.337 kg/L. Putting all this values in formula we get. % of voids = { (2.65 _ 1.337)/2.65} 100. % of voids = (1.313/2.65) 100. % of voids = 0.495 100. Hence % of voids of fine aggregate = 49.5%

Dec 18, 2019 Bulk density of calculated as, Bulk density ϒ= weight of aggregate in kg capacity of the container in liter Percentage of voids={1-ϒ}x100 Where ϒ=bulk density of aggregate in kg/liter G=specific gravity of aggregate 7
