F.M.:Fineness Modulus of AggregatesThe Fineness modulus (FM) is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100.
14.08.2020· FM is an index of the fineness of an aggregate – the higher the FM, the coarser the aggregate; The FM can be looked upon as a weighted average size of a sieve on which the material is retained, the sieves being counted from the finest. Different aggregate grading may have the same FM; FM of fine aggregate is useful in estimating proportions ...
cumulative percentages of aggregate retained on each of the standard sieves ranging from 4.75mm to 150 microns and dividing the sum by an arbitrary number 100. The larger the value, the coarser is the material. Fine aggregate is classified as coarse sand, medium sand and fine sand based on the fineness modulus (IS 2386 - PART III 1963) as shown ...

Fineness modulus - WikipediaFine aggregates range from a FM of 2.00 to 4.00, and coarse aggregates smaller than 38.1 mm range from 6.75 to 8.00. Combinations of fine and coarse aggregates have intermediate values. Fineness modulus of combined aggregates Fineness ... is proportion of fine aggregate in combined aggregate.
A Study of Concrete Made with Fine and Coarse .This paper deals with the possibility of using fresh concrete waste as recycled aggregates in concrete. An experimental program based on two variables (proportion of fine aggregates replacement and proportion of coarse aggregates replacement) was implemented. The proportions of replacement were 0%, 50%, and by mass of aggregates.
Sieve Analysis of Fine Aggregates || Procedure .Aggregates size varies from several inches to the size of the smallest grain of sand. The Aggregates(fine + coarse) generally occupy 60% to 75% of the concrete volume or 70% to 85% by mass and strongly influence the concrete's freshly mixed and hardened properties, mixture proportions.
The proportions of cement, sand, coarse aggregate and water plays an important role in determining the fresh and hardended properties of concrete. So care should be taken while calculating the amount of Cement, Sand and Aggregate required for 1 Cubic meter of Concrete.Study on Tests Fine and Coarse Aggregate .Fine and coarse aggregate is very necessary target result for every RCC and road side Department. 2. Must be tests Fine aggregate and coarse aggregate. 3. It's should be necessary to test of aggregate from used materials. 4. It must be quality control fine aggregate and coarse aggregate. 5. Skilled work are need in use fine aggregate and ...CHAPTER 3 PROPERTIES OF MATERIALS - Shodhgangacumulative percentages of aggregate retained on each of the standard sieves ranging from 4.75mm to 150 microns and dividing the sum by an arbitrary number 100. The larger the value, the coarser is the material. Fine aggregate is classified as coarse sand, medium sand and fine sand based on the fineness modulus (IS 2386 - PART III 1963) as shown ...Effect of Sand Fines and Water/Cement Ratio on Concrete ...of coarse aggregate was 0.5% which was within the normal range from0.1 to 0.6%.The fineness modulus obtained suggest that, the aggregates used had an approximately average sizes of 600µm and 12.5mm for fine and coarse aggregates respectively. Thus, the sand used was normal sand since it lies within Zone II of geological grading.
