density of crush sand and coarse aggregate

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, ... Fine aggregate. Coarse sand. Fig. 5-6. Curves indicate the limits specified in ASTM C 33

Aggregate density:- density of coarse sand/ gravel/ aggregate is ranging between 1450 – 2082 kg/m3 in metric system or 75 – 110 lb/ ft^3 based in Imperial and US customary measurement system depending on different condition like wet, dry, loose, dry packed and wet packed

Essential Points. 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 relative density (specific gravity) of an aggregate is the ratio of its mass to the mass of an equal volume of water. Relative Density = Mass of the Aggregate / Mass of equal volume of water. Key Features: Most aggregates have a relative density between 2.4-2.9 with a corresponding particle (mass) density of 2400-2900 kg/m3 (150-181 lb/ft3)

Coarse aggregate is having a particle size of more than 4.75 mm as per IS. Coarse aggregate is used to form a main body of concrete along with sand and cement mix with water in concrete. The maximum size of coarse aggregate used for concrete making is 20 mm. Aggregates used for construction must be chemically inactive in nature

Fine Aggregate Sand and/or crushed stone. 4.75 mm. F.A. content usually 35% to 45% by mass or volume of total aggregate. Coarse Aggregate Gravel and crushed stone. 4.75 mm. Typically between 9.5 and 37.5 mm

2.1.2 Crushed Stone Sand - Fine aggregate produced by crushing hard stone. 2.1.3 Crushed Grace1 Sand - line aggregate produced by crushing natural gravel. . 2.2 Coarse Aggregate -- Aggregate most of which is retained on 4*75-mm IS Sieve and containing only so much finer material as is permitted for

The density of crushed concrete aggregate is smaller than natural aggregate density. 4. Water Absorption ... However, concrete produced from coarse recycled aggregate and natural sand provide approximately the same flexural and tensile strength as concrete made from natural aggregate. The standard size of beams for flexural tests according to

Density of coarse Aggregate. Following are the density of coarse aggregate. Broken stone ballast. Dry well shaken=1600—1870 kg/cum. Perfectly wet =1920—2240 kg/cum. Shingles 3-38mm=1460 kg/cum. Gravel. Loose = 1600 kg/ cum. Un disturbed =1920-2160 kg/cum

An estimated density factor should then appear in the above density field. Geology: Traprock Limestone Granite Sand & Gravel Sandstone Other Product: Screenings Crushed Stone Base / Crusher Run Coarse Aggregates Sand Riprap Other

This density for practical purposes has to be determined at site for arriving at the exact quantities. We can also assume the following dry loose bulk densities for calculation. DLBD of Sand = 1600 kgs/cum. DLBD of Aggregate = 1450 Kgs/Cum. So, Sand required = 0.072*1600 = 115 kgs. and Aggregate required = 0.144*1450 = 209 kgs

When sand is in wet condition, water is present in sand particles that change material quantity in the volume. The average density of sand in a different state are as follows: Loose Sand Density: 1442 Kg/m3. Dry Sand Density: 1602 Kg/m3. Packed Sand Density: 1682
