Types of Sieves: There are different types of sieves such as # 10, # 100,# 200,# 300 etc. The number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement, following number sieve is recommended by ASTM. Cement by wet process = # 300 sieve. Cement by dry process = # 200
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 []
The fineness of cement is a measure of the size of particles of cement and is expressed in terms of specific surface area of cement. Fineness can be calculated from
What is meant by fineness of cement, and why it . Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass. FINENESS LIMIT: It should not exceed the following percentage by weight for different types of cement. Ordinary Portland cement =10%; Rapid hardening cement =5%; Low
The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate :1996 Methods of Physical Tests for Hydraulic Cement: Determination of Fineness by Dry Sieving (second Check the sieve after every 100 sieving as per
#0183;#32;To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) 1996. Principle. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) 90m IS Sieve.
