Oct 01, 2016 · Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Fineness modulus is generally used to get an idea of how coarse or fine the aggregate is.

Standard Specifiion for Fine Aggregate for Portland Cement Concrete AASHTO Designation: M 603 1. SCOPE 1.1. This specifiion covers the quality and grading of fine aggregate for portland cement concrete used in pavements or bases, highway bridges, and incidental structures.
The standard fine aggregate specific gravity and absorption test is: AASHTO T 84 and ASTM C 128: Specific Gravity and Absorption of Fine Aggregate Background. Specific gravity is a measure of a material''s density (mass per unit volume) as compared to the density of water at 73.4°F (23°C). Therefore, by definition, water at a temperature of
Dec 01, 2014 · Fine aggregates pass the 3/8inch sieve and are retained on a #200 U.S. sieve. 6. Fine Aggregate. Fine aggregate consists of natural sand, manufactured sand, or a combination. The ASTM C33 specifiions for fine aggregates for concrete are given in Table 1. 3. Table 1 3 ASTM Gradation Specifiions for Fine Aggregates for Portland Cement Concrete
recommends that if fine aggregates have a high proportion of fine material (manifested by a low fineness modulus), then the amount of coarse aggregate should be increased, thereby indirectly decreasing the quantity of fine aggregate in the concrete mixture. WG combined aggregate obtained % NWG WG NWG WG %
Specifiion of Fine Aggregate/Coarse Sand . Fine Aggregate Fine aggregate/ coarse sand consists of natural sand, crushed stone sand or crushed gravel stone dust. It should be hard, durable chemically inert, clean and free from organic matter, not containing any appreciable amount of clay balls or pellets and other harmful impurities i. e
Jan 15, 2016 · Aggregate serves as a reinforcement to add strength to composite materials such as concrete. Aggregates can be egorized into three groups: fine aggregate, coarse aggregate, or allin aggregate. Fine aggregate, such as concrete or masonry sand is defined as material that mostly passes through a 4.75 mm IS sieve.
scope: This specifiion defines the requirements for grading and quality of fine and coarse aggregate (other than lightweight or heavyweight aggregate) for use in concrete. 2 This specifiion is for use by a contractor, concrete supplier, or other purchaser as part of the purchase document describing the material to be furnished.
May 17, 2017 · Concrete Mix Design:Concrete is a composite mixture which consists of Cement, Sand and Aggregate. Concrete mix design is the procedure for finding the right quantities of these materials to achieve the desired strength.
Jun 01, 2019 · Aggregates are the major constituent (ingredient) in concrete, making up 60% to 70% of the volume of concrete. Aggregates influence the workability of plastic concrete and also the durability, strength, thermal properties, and density of hardened concrete. Particle size divides aggregates into two egories: fine and coarse. Most fine aggregates are sand and contain particles smaller than 3/8

Fine aggregate should fall within gradation limits provided in ASTM C 33, Section 6. If there is a deficiency in a locally available fine aggregate, concrete may benefit from the addition of air entrainment, additional cement, or a supplemental cementitious material (SCM) to
1102 AGGREGATES FOR CONCRETE SECTION 1102 AGGREGATES FOR CONCRETE 1102.1 DESCRIPTION This specifiion is for coarse aggregates, intermediate aggregates, fine aggregates, mixed aggregates (both coarse and fine material) and miscellaneous aggregates for use in all types of concrete construction. 1102.2 REQUIREMENTS a. Coarse Aggregates for
Jun 02, 2012 · This experiment is carried out to find and check the gradation of the fine aggregate i.e. sand. The concrete consists of three basic solid materials, one is the sand whose fineness is checked by experiment no 1, the other two materials are the coarse aggregate that is the crush while the third is the fine aggregate that is the sand.
Fine aggregate is the essential ingredient in concrete that consists of natural sand or crushed stone. The quality and fine aggregate density strongly influence the hardened properties of the concrete.. The concrete or mortar mixture can be made more durable, stronger and cheaper if you made the selection of fine aggregate on basis of grading zone, particle shape and surface texture, abrasion
