ii) the percentage by weight of the total sample passing through one sieve and retained on the next smaller sieve, to the nearest 0.1 percent. The results of the sieve analysis may be recorded graphically on a semi-log graph with particle size as abscissa (log scale) and the percentage smaller than the specified diameter as ordinate.
2009-12-20 · Aggregates that predominantly show size fractions in a limited range of sizes (such as the 20 mm and 10 mm aggregate in Figure 1) are called ‘uniformly’ graded, while aggregates that show a continuous gradation of size (sand in Figure 1) are called ‘well’ graded or continuously graded.
sample. Sieve analysis provides the basis for obtaining the specific grading of aggregate as provided in the specifiions of a job. Fineness Modulus (F.M.) is an index of coarseness or fineness of the material. F.M. is obtained by adding the cumulative percentages of aggregate retained on each sieve ranging from 80 mm
2018-11-29 · A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil 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

2013-3-16 · Pan: a metal or plastic pan of sufficient size to contain the funnel stand and to prevent loss of material. The purpose of the pan is to ch and retain fine aggregate particles that overflow the measure during filling and strike off. 6. Metal Spatula: a spatula with a blade approximately 100 mm in length and at least 20 mm wide with straight
The aggregates used for making concrete are normally of the maximum size 80 mm. the particle size distribution in a sample of aggregate is found. 10 mm. Aggregates from 80 mm to 4.36 mm.47 mm.M is an index of coarseness or fineness of the material. a term known as “fineness modulus” (F. with the larger sieve on top.75 mm are termed coarse
2016-7-31 · Fineness modulus of coarse aggregates represents the average size of the particles in the coarse aggregate by an index nuer. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fine aggregate.
6.4 Preparation of the Test Sample — The amount of aggregate available shall be sufficient to provide, after separation on the appropriate pair of sieves, at least 10 kg of the predominant size, as determined by the sieve analysis on the 20-mm, 16-mm, 12*5-mm; 10-mm, 6''3-mm and 4*75-mm IS Sieves.
