• ### Aggregate Properties The Concrete Portal

The grading of the aggregate can be distinguished based on the sieve analysis. 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 ...

• ### Sieve Analysis, Particle Size Analysis Civil Engineering

Sieve analysis is used to determine the grain size distribution of coarsegrained soils. For the particle size distribution of finegrained soils, a hydrometer analysis is used. Particle size distribution is represented on a semi logarithmic plot of % finer (ordinate, arithmetic scale) .

Jan 23, 2018· Sieve analysis of Aggregates. iii) On completion of sieving, the material on each sieve is weighed. iv) Cumulative weight passing through each sieve is calculated as a percentage of the total sample weight. v) Fineness modulus is obtained by adding cumulative percentage of aggregates retained on each sieve and dividing the sum by 100.

• ### ASTMC136 | Standard Test Method for Sieve Analysis of ...

Some specifications for aggregates which reference this test method contain grading requirements including both coarse and fine fractions. Instructions are included for sieve analysis of such aggregates. The values stated in SI units are to be regarded as the standard. The values in parentheses are provided for information purposes only.

• ### Sieving methods of sieve analysis

Tap sieve shakers are specified in various standards for particle size analysis. The number of comparisons between particles and sieve apertures is substantially lower in tap sieve shakers than in vibratory sieve shakers ( s1 as compared to ~50 s1) which results in longer sieving times.

• ### Sieve Analysis Test Of Aggregates Engineering Discoveries

Aim. To determine the particle size distribution of fine and coarse aggregates by sieving as per IS: 2386 (Part I) – 1963. Principle. By passing the sample downward through a series of standard sieves, each of decreasing size openings, the aggregates are separated into several groups, each of which contains aggregates in a particular size range.

Percent Passing values for the sieve below it in the analysis table. Example: Find the % Passing for the No. 100 sieve for the No. 8 aggregate (above). % passing #100 = % retained on #200 + % passing #200 = + = Example: Find the % Passing for the No. 4 sieve for the No. 8 aggregate (above).
