Aggregates for Concrete - Memphis
aggregates—sand, gravel, crushed stone, and air-cooled blast-furnace slag—produce freshly mixed normal-weight concrete with a density (unit weight) of 2200 to 2400 kg/m. 3 (140 to 150 lb/ft. 3). Aggregates of expanded shale, clay, slate, and slag (Fig. 5-3) are used to produce struc-tural lightweight concrete with a freshly mixed density
Aggregates for Concrete
with “density” when used in reference to the absolute volume aggregates occupy in concrete, and with “bulk density” when used in reference to aggregates, such as the mass per unit volume of a collection of graded aggregate particles as compacted in a volumetric bucket or the relation of mass to volume of aggregates in a stoc kpile or bin.
Fine Aggregates: Types, Properties & Uses in construction
The specific gravity of aggregates is the ratio of the density of water to its density. It is used for concrete mix design and if not specified the specific gravity is taken as 2.7 because the specific gravity of most aggregates obtained from different sources falls between 2.6 and 2.8. 5.Surface Texture of fine aggregates:
Lightweight Aggregate - an overview | ScienceDirect Topics
Lightweight aggregates (LWA) are defined as construction materials that have a bulk density lower than that of common construction aggregates (Choudhry and Hadley, 2009). It is possible to manufacture LWA and ultra LWA from gasification slag and fly ash, according to Choudhry and Hadley (2009) and Sloss (1996) .

Aggregatesare the most mined materials in the world. Due to the relatively high hydraulic
Properties of aggregates- Physical properties, Chemical,
The bulk density of an aggregate sample is determined by filling a unit volume cylindrical container with aggregates at a specific degree of compaction. Thus it depends on the degree of compaction of aggregates during filling of the container and accordingly has been divided into categories of loose and compact bulk density.

Packing Density - an overview | ScienceDirect Topics
It also seems that the particle’s angularity has a strong influence on packing density: de Larrard (1999) reported that rounded aggregates give a packing density close to 0.60 while crushed aggregates packing gives values between 0.50 and 0.57. Such results suggest that packing density can be related to a ‘roundness’ factor and some attempts to do this have been

Most of the aggregates possess a relative density within 2.4 – 2.9 with a similar particle density about 2400-2900 Kg/m 3 (150-181 lb/ft 3). Hereabouts, for coarse aggregates, the standard test process has been described in ASTM C 127(AASHTO), and for fine aggregates, the standard test practice has been described in ASTM C 128 (AASHTO).
The Effect of Aggregate Properties on Concrete
The density of the aggregates is required in mixture proportioning to establish weight-volume relationships. 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.
Classification of Aggregates
Classification of Aggregates. The variability in density can be used to produce concrete of widely different unit weights, see Table (1). The most common classification of aggregates on the basis of bulk specific gravity is lightweight, normal-weight, and heavyweight aggregates.
