Aggregate is classified into two general sizes: coarse grained and fine grained. Coarse aggregate is rock retained on a 3/8-inch (#4 U.S. sieve). Fine aggregates pass the 3/8-inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination.
Most specifications require coarse and fine aggregate to conform to the requirements, including the gradation, of ASTM C33. Concrete producers then use that …
1. Grading. The fine aggregate shall not pass 45% from a single sieve and retained on the next consecutive sieve as shown in table-1. The fineness modulus of the fine aggregate shall be not less than 2.3 and more than 3.1. The …
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed …
In general, ACI recommends that maximum aggregate size be limited to 1/3 of the slab depth and 3/4 of the minimum clear space between reinforcing bars. Aggregate larger …
The standard ASTM C33 specifies that fine aggregate should pass through a sieve with openings of 9.5 mm (3/8 inch) and be retained on a sieve with …
ASTM C33. This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.
ASTM C33. This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, …
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, …
Fine aggregate can be found in four different moisture conditions namely: oven-dry (OD), air-dry (AD), saturated-surface dry (SSD) and wet. Only OD and SSD correspond to a specific moisture state and can be used as …
Aggregates may be broadly classi fied as natural or artificial, both with respect to source and to method of preparation. Natural sands and gravels are the product of weathering and the action of wind or water, while manufactured crushed fine aggregate and crushed stone coarse and fine aggregate are produced by crushing natural stone.
This specification defines the requirements for grading and quality of fine and coarse aggregate for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Fine aggregate shall be free of injurious amounts of organic impurities.
Most specifications require coarse and fine aggregate to conform to the requirements, including the gradation, of ASTM C33. Concrete producers then use that material to make concrete, the properties of which are quite dependent on the aggregate gradation, both coarse and fine.
1. Grading. The fine aggregate shall not pass 45% from a single sieve and retained on the next consecutive sieve as shown in table-1. The fineness modulus of the fine aggregate shall be not less than 2.3 and more than …

ASTM C 33-13 specification covers the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete. Fine aggregate shall consist of natural sand, manufactured sand, or a combination thereof. Grading requirements of fine aggregates shall be as given in the adjoining input ...
Fine aggregate can be found in four different moisture conditions namely: oven-dry (OD), air-dry (AD), saturated-surface dry (SSD) and wet. Only OD and SSD correspond to a specific moisture state and can be used as reference states for calculating moisture content.
The standard ASTM C33 specifies that fine aggregate should pass through a sieve with openings of 9.5 mm (3/8 inch) and be retained on a sieve with openings of 75 μm (No. 200). In general, fine aggregates include particles that …
In general, ACI recommends that maximum aggregate size be limited to 1/3 of the slab depth and 3/4 of the minimum clear space between reinforcing bars. Aggregate larger than these dimensions may be difficult to consolidate and compact resulting in a honeycombed structure or large air pockets.
