Apr 07, 2020 · An increase in fineness increases the amount of gypsum required for proper retardation because, in a finer cement, more C3A is available for early hydration. The water content of a paste of standard consistency is greater the finer the cement, but conversely an increase in fineness of cement slightly improves the workability of a concrete mix… Read more

fineness modulus of cement bydry sieving

The Fineness modulus of cement 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. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Contents:Fineness Modulus […]… Read more
