fineness test of concrete

Fineness Test of Cement; Its Apparatus, Procedure.

And after testing, you found the retained weight of cement on the sieve, Let it be 65 grams (w2). Now put the values in the formula; % of retained weight of cement = (65/1000) x 100. SO, the result of a fineness test of cement will be 6.5 % which is below the IS value (10%) and hence cement is in good condition.

Fineness test for cement, its Procedure & Apparatus

Sep 01, 2020· Degree of fineness for cement is the measure of size of grain in it, there are three methods of testing of fineness of cement: 1) Sieve methods using 90 micron sieve, 2) Air permeability methods Nurse and Blaines method and 3) Sedimentation method Wanger turbidimeter method. Sieve method measure grain size where as their permeability and sedimentation method measure

Fineness test of cement Formula with Table of Calculation

What is fineness test of cement? The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement.

Fineness Test of Cement by Dry Sieving or Sieve Analysis

Mar 27, 2020· Fineness test is used in checking the proper grinding of cement and measuring the surface area of the cement particles per unit mass. As well as fineness of cement increases, the requirement of water for workability also increases which results in a higher possibility of dry shrinkage.

Fineness of Cement Construction How

Dec 23, 2020· However, the sieve test gives no information on the size of grains smaller than 45 μm (No. 325 ASTM) sieve, and it is the finer particles that play the greatest part in the early hydration.; For this reason, modern standards prescribe a test for fineness by determination of the specific surface of cement expressed as the total surface area in square metres per kilogram.

Cement Fineness| Concrete Construction Magazine

Aug 01, 1970· 6. For concrete containing no entrained air, there is a slight decrease in the static modulus of elasticity at 28 days' age as the fineness is increased. The modulus of elasticity of concrete determined by sonic methods decreases as the fineness of the cement increases. 7. The fineness of cement influences the drying shrinkage of concrete. When

Effects of cement fineness on cement properties

Effects of cement fineness on cement properties. Q. How does the fineness to which the clinker is ground affect the properties of the cement? A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150).
