Test Procedure for Fineness Modulus of Coarse Aggregates. Arrange the sieves in descending order and put the arrangement on mechanical shaker. It is suggested that, to know the exact value of fineness modulus for coarse aggregate, mechanical shaker will give better value than hand shaking because of more no. of sieves and heavy size particles.Get Price
Grading of aggregates is aimed at determining the mean size of the particle in a given batch of aggregates. This is commonly found by the Method of Fineness Modulus. The method can be used to determine fineness modulus of coarse aggregates, fine aggregates, and allin aggregates, i.e., mixed aggregates.
Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods 1. Sieving Method. 2. Air Permeability Method Blaine Method.

Ravindra K. Dhir OBE, Chao Qun Lye, in Sustainable Construction Materials Copper Slag, 2017. 3.4.3 Fineness Modulus. The significance of fineness modulus FM is in specifying the proportions of fine and coarse aggregates when designing concrete mixes. The higher the value of FM, the coarser the aggregate. Generally, a lower FM results in more paste, making the concrete easier to finish.
Test Procedure for Fineness Modulus of Coarse Aggregates. Arrange the sieves in descending order and put the arrangement on mechanical shaker. It is suggested that, to know the exact value of fineness modulus for coarse aggregate, mechanical shaker will give better value than hand shaking because of more no. of sieves and heavy size particles.
Calculating Fineness Modulus. The simple procedure to compute FM requires performing an accurate particle size analysis as detailed in ASTM C136, Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates. In addition to the sizes needed for particle sizing, specific to the FM calculations must be included as well.

The object of this experiment is to determine the fineness modulus and hence to plot the particle size distribution curve for the sample of fine aggregate supplied. Theory The fineness modulus of a sample of aggregate is an index number which is roughly proportional to the average size of particle in the aggregate, that is, coarser the
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. More fineness modulus value indicates that the
SIEVE ANALYSIS OF FINE AND COARSE AGGREGATES AASHTO T 27 SCOPE The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation the distribution of aggregate particles, by size, within a given sample in order to determine compliance with design
