The Fineness test of cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose size greater than 90 microns is determined and the percentage of retained cement particle are calculated. This is known as Fineness of cement.

What is the fineness of the cement? A Fineness of Cement is Measure of the size of Cement Particle, and it is described in terms of the specific surface area of Cement particle. The Fineness of cement can be Calculated by particle size analysis, by using the air permeability method, by using sedimentation method.

Cement Cement Cement testing Various tests to which cements must conform are laid down in national cement specifications to control the fineness, soundness, setting time, and strength of the cement. These tests are described in turn below. Fineness was long controlled by sieve tests, but more sophisticated methods are now largely used.

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.

In the early 1900s, cement fineness was expressed as the mass of cement per fractional size percent weight retained on specific sieve sizes. Now a days fineness is usually measured by the Blaine airpermeability test that indirectly measures the surface area of the cement particles per unit mass. Cements with finer particles have more

Procedure to Determine Fineness of Cement. Stir the sample of cement to be tested by shaking for 2 minutes in a stoppered jar to disperse lumps. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement. Attach a pan under the sieve to collect the cement passing the sieve.

2. Increasing the fineness of cement from 2700 to about 4000 cm2g reduces the water requirement of concrete. Increasing the fineness of cement beyond an optimum limit increases the water requirement of concrete. 3. The workability of non airentrained concrete is increased by increasing the cement fineness. In airentrained concrete the effect
