Fineness Modulus of Cement by Dry Sieving

Sep 26, 2018· 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 []

What is meant by fineness of cement, and why it is necessary?

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. 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

What is Fineness of Cement? Importance & Test Procedure

It should not be greater than 90-microns when sieved as per IS standard. Importance of fineness of cement. More cement coarse particles affect and reduce the rate of hydration. If the hydration rate decreases, then it impacts the strength development of concrete or mortar. More fineness induces dry cracks on concrete surfaces. Fineness cement

Fineness of Cement

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 of evolution of heat. Wait 2 min. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. Check the sieve after every 100 sieving as per para 4.4.2
