2021-8-11 · Fineness Modulus. Fineness modulus (FM) is a numerical index obtained from the sieve analysis test result. The FM is the sum of the total percentages coarser than each of a specified series of sieves, divided by 100. In the figure-3, the sum of total cumulative percentage retained divided by 100 gives the fineness modulus.Solved Answer with( True or False) with explanation:1) The ...Answer with ( True or False) with explanation: 1) The larger the fineness modulus the finer is the grading. 2) Gray cement color is achieved from Ferrous clay minerals. 3) The surface area increases as the max aggregate size increase. 4) Fineness of cement accelerate strength development. 5) Air entrained admixture is more useful in hot climate.

What is the effect of fineness of cement?

What is the effect of fineness of cement? Increasing fineness causes an increased rate of hydration, high strength, and high heat generation. Bleeding can be reduced by increasing fineness. However, increased fineness can also lead to the requirement of more water for workability, resulting in a higher possibility of dry shrinkage neness test of cement | Formula with Table of CalculationThe proportion of cement size greater than 90 microns is considered as fineness cement.
