What is the definition of fineness modulus?
Fineness Modulus is a measurement of the coarseness or fineness of a given aggregate.
How does fineness modulus of aggregates affect the strength of concrete?
how does the fineness modulus of aggregate affect the strength of concrete
Why fineness modulus of coarse aggregates is more than that of fine aggregates?
how does the fineness modulus of aggregate affect the strength of concrete
What is the significance of fineness modulus?
Fineness Modulus is used to know the size of aggregate grains (Particles) for various measurements used in Civil Engineering. To characterize the overall coarseness or fineness of an aggregate, a concept of fineness modulus is developed. The Fineness Modulus is defined as Fineness Modulus = Σ(Cumulative Retained Percentage) 100 To calculate the fineness modulus, the sum of the cumulative percentages retained on a definitely specified set of sieves needs to be determined, and the result is then divided by 100. The sieves specified for the determination of fineness modulus are No. 100, No. 50, No. 30, No. 16, No. 8, No. 4, 3/8", 3/4", 1.5", 3", and 6". Mirza Usman http://www.facebook.com/Mirza.Usman.Blogger

What is the fineness modulus of sand?
The Fineness Modulus (FM) is an index number which is roughly proportional to the average size of the particles in an aggregate sample. It is obtained by adding the cumulative percentages coarser than each of the standard sieves used for segregating sand and dividing the cumulative percentage by 100.

What is Significance of fineness modulus?
Optimum for grading of aggregates and for surface texture of constructions.
What is the practical use of controlling the grading of concrete aggregate?
Fineness modulus defines the size of the of the aggregates on concrete mix design. There area some limits on it though. If you have high modulus of fineness, the tendency of mixture is to have less pores as possible. The less pores you have, the good is your bonding between each elements. However,less pores means less breathing space for your concrete. This inhibits hydration. Once moisture doesnt escape from concrete, then the strength is very difficult to achieve. On the other hand, low modulus of fineness tend to have lower bonding between concrete elements. However, you can have better curing condition of you have optimum pores on your concrete. The strength can be achieve quickly.
