high-density aggregate. In addition, the relative density of the aggregate is used in calculating the absolute or solid volumes of materials in a concrete mix and thus the yield. The apparent relative density of aggregate generally varies between 2.5 and 3.0. Water absorption The extent to which pores in the aggregate structure can

Slag, crushed 1/4 inch weighs 1.185 gram per cubic centimeter or 1 185 kilogram per cubic meter, i.e. density of slag, crushed 1/4 inch is equal to 1 185 kg/m³. In Imperial or US customary measurement system, the density is equal to 73.98 pound per cubic foot [lb/ft³], or 0.685 ounce per cubic inch [oz/inch³] .
The particles formed are round in shape and generally range in size from 0-30 mm. Expanded Clay Aggregate (ECA) are up to 6 times lighter than traditional aggregates. Expanded Clay Aggregate ( ECA ) is a preferred material due to its ability to reduce earth pressure up to 75% compared to conventional materials in the market.
The approximate bulk density of aggregate that is commonly used in normal-weight concrete is between 1200-1750 kg/m 3 (75-110 lb/ft 3). Here, Standard test method for determining the bulk density of aggregates is given in ASTM C 29 (AASHTO T 19).

Granular soils range in particle size from .003" to .08" (sand) and .08" to 1.0" (fine to medium gravel). Granular soils are known for their water-draining properties. Characteristics Sand and gravel obtain maximum density in either a fully dry or saturated state. Testing curves are relatively flat so density can be
Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural gravel and sand are:J Singletongreen:Fineness · Bulk density · Absorption · Impurity · Grading · Specific gravity
Crushed stone may be made from granite, limestone, dolomite, and other rocks. Also known as "crusher run", DGA (dense grade aggregate) QP (quarry process), and shoulder stone. Fine gravel: gravel consisting of particles with a diameter of 2 to 8 mm.
Properties of Aggregates and its Values for use in Construction Home / How To Guide / Properties of Aggregates and its Values for use in Construction Properties of aggregates such as bulk density, specific gravity, voids, water absorption and its values are presented in this article.
Jun 09, 2005· Aggregate Base Density Data. However, since the aggregate is made up of particles, it is reasonable that the compacted density of the aggregate is between (150-180 lb/ft^3). If you consider an entire road bed compacted at 95%, would it be reasonable to estimate that the density of the aggregate road bed is 165REVISED POST (Revision two the second to last paragraph in the above post) I am converting (CY) of aggregate (for a road construction project) tYou need to talk to someone with experience in doing this calculation. For example, the weight of poured in place concrete, with reinforcement, isJedClampett sorry, but we have compacted crushed stone coming in at over 150pcf. Why? Our specific gravity is 3.0. I agree with you. M076 canHere in Washington the state DOT provides guidance for engineer's to prepare their estimates that includes unit densities for different materials,It depends on the gradation of the rock and the compative effort being put into the rock. In the Midwest for a material with some fines, the maximthis is standard information that can be obtained from your geotech, your highway department, your local material supplier or your favorite contracI my region (the Atlanta, GA area), most of the granite quarried has a density of around 150 pounds per cubic foot (pcf) Most pavers use 110 pound1I agree, call the local quarries and contractors for your best guess.

upon density, Listed below are some of the factors that affect the density of dense graded aggregate base constructed from crushed limestone. 1. Specific Gravity and ;Porosity of Solid Stone. The specific gravity usea-is termed "bulk specific gravity (SSD basis)" by ASTM and is the saturated surface dry weight divided by the bulk:William B Drake:Aggregate base

This weight is greatest within 5 to 8 percent moisture content. Thus the Maximum Density of aggregates is determined at a moisture content ranging from 5 to 8 percent, as follows: 1) Run a series of cone tests with moisture content of the aggregate at different points within the 5 to 8 percent range.
