ARDEX COARSE AGGREGATE is a dry, prepacked 3mm graded aggregate for use with ARDEX Subfloor Smoothing Compounds where thicker applications are required. ARDEX FINE AGGREGATE is a dry, prepacked 1 to fine aggregate used for fully blinding ARDEX R 3 E, R 5 E or R 6 E and ARDEX PSRS, to give a 'sand paper' finish.

Crushed Sand (Fine Aggregate) 0 – 5 mm (9% to 11% filler) Classified Crushed Sand (Fine Aggregate) 0 – 5 mm (less than 3% filler) Crushed Aggregate (Coarse Aggregate) 5 – 10 mm; Crushed Aggregate (Coarse Aggregate) 10 – 20 mm; Crushed Aggregate (Coarse Aggregate) 20 – 25 mm; Crushed Aggregate (Coarse Aggregate) 20 – 32 mm
This procedure covers sampling of coarse, fine, or a combination of coarse and fine aggregates (CA and FA) in accordance with AASHTO T 2. Sampling from conveyor belts, transport units, roadways, and stockpiles is covered.
Aggregate and supplementary granular material shall consist of sound durable particles of crushed rock, gravel, stone, sand and fines free from sod, roots and organic material. The crush count is the percentage by weight of aggregate particles retained on a sieve
Coarse aggregates are materials having a nominal size greater than 5 mm and consisting of crushed rock gravel or metallurgical slag that is clean, dry, hard, tough, sound and free from dust, clay, dirt or other deleterious matter.
Water Absorption. It is the ratio of weight of water absorbed to the weight of dry sample expressed as a percentage. It will not include the amount of water adhering to the surface of the particles. COARSE AGGREGATES. Any material which is retained on BS sieve #4 .
Hanson can supply a wide range of aggregates which are suitable for use as fill materials in a variety of construction applications. Hanson has extensive experience in supplying high quality aggregates for concrete and readymixed concrete across the UK. We can supply a wide range of coarse,...
Coarse material washers are used to remove a limited amount of dirty material from a coarse aggregate. They are often used as a final wash following a wet screen and are designed to scrub and clean gravel and crushed stone up to 75mm (3'') in size.
Coarse segregation. Occurs when gradation is shifted to include too much coarse aggregate and not enough fine aggregate. Coarse segregation is characterized by low asphalt content, low density, high air voids, rough surface texture, and accelerated rutting and fatigue failure (Williams et. al., 1996b [5] ).
Aggregate base course is an engineered mixture of coarse and fine aggregate designed to support heavy loads and is used in many applications such as foundations for highways and buildings as well as support of equipment on unpaved surfaces such as job site roads and oil well pads.
Revision History and Document Control. The Manual of Aggregate Quality Test Procedures will be reviewed by the Aggregate Technology Coordinator for adequacy and updated as necessary to reflect the current policies and technology changes. Updates are made to the electronic file as needed and hard copies are uncontrolled.
This procedure covers sampling of coarse, fine, or a combination of coarse and fine aggregates (CA and FA) in accordance with AASHTO T 291. Sampling from conveyor belts, transport units, roadways, and stockpiles is covered.
Splitting of aggregates shall be controlled such that the coarse aggregate fraction, before crushing, shall contain no more than 5% passing the 5000 sieve for mix types 1, 2, 3 and 4. In Department sources, the fine fraction shall contain no more than 20% of material retained on the 5000 sieve size.
Seven mixtures of concrete were prepared with coarse aggregate containing two types of coatings: natural fieldcoated aggregates, and manufactured coated samples of dust and clay fines.
Aggregates are basic materials intensively used in civil engineering works and transport infrastructures construction. These materials could be used on their own nature or .
Jun 06, 2014· The use of recycled concrete represents an environmentally friendly solution for minimizing the impact of construction and demolition wastes. In many countries, the incorporation of recycled coarse aggregate (RCA) is a common practice because the maximum contents of RCA are usually limited to approximately 25% of the total coarse aggregate content.
Aggregate Specific Gravity • Bulk specific gravity used to calculate voids in mineral aggregate – critical • Apparent always largest, then effective, bulk gravity always smallest • Gravity can change between ledges in a quarry or if material blended between two aggregate types • Correction factor, between effective and
Washed, coarse sand Applications: Fine Aggregate for Concrete, Bedding Sand for Pavers, Sand Drainage Filters, Landfill Construction, Dam Construction Class I Rip Rap, 517 inches
The petrographic number of a stockpile of coarse aggregate varies by up to 20 on either side of the mean (19 times out of 20). Ministry of Transportation, Ontario Test Method LS609, Rev. No. 23
The density of the recycled coarse aggregate is lower than natural aggregate. When compared with natural aggregate, recycled coarse aggregates have lower density because of the porous and less dense residual mortar lumps that is adhering to the surfaces. When the particle size is increased, the volume percentage of residual mortar will increase too.
The seashells were utilised as partial or total replacement of fine and coarse aggregates in concrete. This paper is a literature review of seashell aggregate concrete.

Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in construction of roads and pavements.
