Fineness Modulus of Fine Aggregate

Fineness Modulus of Fine Aggregate:

Sieve Analysis

The test sample is dried and measured at a steady weight at a temperature of 110 + 50 A set of IS sieves is used to sieve the sample. The substance on each sieve is weighed upon completion of the sieve. As a proportion of the overall sample weight, the average weight moving through each sieve is measured. The fineness module is obtained by applying to each sieve the total percentage of aggregates maintained and by dividing the sum by 100. Read more

Sieve Analysis of Fine Aggregate:

Well graded means the sizes are in nearly equal proportions across the whole range, although the largest and smallest particles would be very different. Uniform gradation means that the particles have a significant proportion of the same dimension. Gap graded or skip graded means that with a few particles of an intermediate scale, most particles are high in size or tiny in size. Targets: The whole sieve analysis technique is to determine the distribution of the particle size of the fine aggregates and to determine if it is appropriate for use in concrete mixing. Read more

Equipment for Testing

Calculation of Sieve Analysis Test

Calculate passing ratios, cumulative percentage held, or percentages to the nearest 0.1 percent in separate scale fractions on the basis of the total weight of the original dry sample. Calculate the fineness modulus (FM) by applying to the sample the average amount of content that is coarser than any of the normal flowing sieves (Cumulative percentage retained) and by dividing the number by 100:150-m (No. 100), 300-m (No. 50), 600-m (No. 30), 1.18-mm (No. 16), 2.23-mm (No. 8), 4075-mm (3/8-in), 37.5-mm (1.5-in) and wider (3 in or 6 in). If any non-standard sieve is used, apply the total percent retention of this sieve during FM measurement to the next lower-sized standard sieve. Read more

Sieve Analysis of Sand

Step 1: Take a representative oven-dried sample that weighs approximately 500g. Step 2: If particles are lumped or conglomerated, crush the lumps but not the particles using the pestle and mortar. Step 3: Determine the mass of the sample accurately – Weight (g). Step 4: Prepare a stack of test sieves . Step 5: Weigh all the sieves and the pan separately. Step 6: Pour the samples from step 3 into the top of the stack of sieves and put the lid on, place the stack in the sieve shaker and fix the clamps, adjust the timer to between 10 and 15 minutes, and switch on the shaker. Step 7: Stop the sieve shaker and measure the mass of each sieve and retained soil/material. Read more
