12. TESTING OF CEMENT – PART 1.

Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1. Sieving Method. 2. Air Permeability Method (Blaine Method).

Fineness of cement test - LinkedIn SlideShare

Apr 06, 2018· Fineness of cement affects hydration rate hence the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume ratio, and thus, the more area available for water-cement interaction per unit volume. Therefore finer cement reacts faster with water and the rate of development of strength and corresponding heat of ...

Determination of Fineness of Cement by Sieving - L & T ...

The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process. As hydration rate of cement is directly related to the cement particle size, fineness of cement is very important. Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength ...

Standard Test Methods for Fineness of Hydraulic Cement by ...

In this experiment, the fineness of cement is to be determined by Sieve Method. By doing so, the cement produced by an industry can be checked for its quality because t he fineness of cement is responsible for the hydration rate and hence on the rate of gain of strength and also on the rate of evolution of heat. In order to determine the fineness of the cement, a 100 g sample of cement …
