mixtures. The aggregate blends included: coarse, fine, and medium gradations and two poorly graded. From this investigation, they concluded that: Variations in gradation have the greatest effect when the general shape of the gradation curve is changed (i.e., coarse-to-fine & fine-to-coarse gradations).

For fine aggregate, no weight shall be in excess of 4 gm/in. 2 (7 kg/m 2). 3. Coarse Aggregates After the material has been sieved, remove each tray, weigh each size, and record each weight to the nearest 0.1 g. Be sure to remove any aggregate trapped within the sieve openings by gently working from either or both sides with a trowel or

Fine Gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly above the 0.45 power maximum density line. The term generally applies to dense graded aggregate. Coarse Gradation. A gradation that, when plotted on the 0.45 power gradation graph, falls mostly below the 0.45 power maximum density line.

A sieve analysis (or gradation test) is a practice or procedure used in civil engineering and chemical engineering to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

aggregate per unit volume of concrete is selected, for the particular maximum size of coarse aggregate and fineness modulus of fine aggregate. The weight of C.A. per cubic meter of concrete is calculated by multiplying the bulk volume with bulk density. From Table 11.4, for 20 mm coarse aggregate, for fineness

Opening sizes and mesh diameters for test sieves are often duplicated between these two standards, making it easier to select the proper sieve size for your material. The above table is a list of all available sieves in U.S. and metric sizes for both ASTM E11 and ISO 565/3310-1. Sieve mesh opening sizes range from 5in (125mm) down to #635 (20µm).

An example provided in the ACI 211 standard states that, "For a fine aggregate having a fineness modulus of 2.8 and a 37.5mm nominal maximum size of coarse aggregate, the table indicates that 0.71m3 of coarse aggregate, on a dry-rodded basis, may be used in each cubic meter of concrete. The required dry mass is, therefore, 0.71 x 1600 = 1,136kg."

aggregate size numbers. Fine aggregate or sand has only one range of particle sizes for general construction and highway work. The grading and grading limits are usually expressed as the percentage of material passing each sieve. Fig. 5-6 shows these limits for fine aggregate and for one size of …

This specification covers fine aggregate for use in bituminous paving mixtures. The aggregate shall be sampled to meet the requirements prescribed. Grading, fineness modulus and plasticity index shall be tested to meet the requirements prescribed. This abstract is a brief summary of the referenced standard.

According to size the aggregates are classified as: Fine Aggregate Coarse Aggregate All in Aggregate Fine Aggregate It is the aggregate most of which passes 4.75 mm IS sieve and contains only so much coarser as is permitted by specification.

All Aggregates pass IS 4.75 mm sieve is classified as fine Aggregates. All aggregate technicians use the sieve analysis (gradation test) to determines the gradation (the particle size distribution, by size, within a given sample) in order to determine compliance with design, production control requirements, and verification specifications.

FM & Gradation are NOT the SAME 30 Fine Aggregate Gradation • Fineness Modulus (FM) should be between 2.3 and 3.1 • FM is empirical # determined by dividing the sum of percent retained on a standard series of sieves by 100 (No. 4, 8, 16, 30, 50, 100) • Coarser fine aggregate has a higher FM Sieve Percent Passing 3/8 in 100 No. 4 95-100

Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates. Following are the classification of aggregates based on size: Aggregates are classified into 2 types according to size. Fine aggregate
