Conclusion After the experiment, our group was able to determine the fineness of the cement by sieve method. Based on our results, we have observed that sieving process should be done properly and carefully. In our data, the average fineness of the fineness of the cement is 97.62% which means it passed the standard because it is clearly not less than 78%.

There are three method of checking fineness of cement. 1. By dry sieving as described above, 2. Blaine air permeability method and 3. By wet sieving.
Get PriceFineness test of cement is a simple test that involves the determination of the fineness of the cement simply by sieving the cement. In general, the test includes determination of the weight of the cement particles whose size is greater than 90 microns and thus the percentage retained is computed.

Get PriceCement: Fineness Test . The degree of fineness of cement is the measure of the mean size of the grains in it. There are three methods for testing fineness: the sieve method-using 90 micron (9 No.) sieve, the air permeability method-Nurse and Blains method and the sedimentation method-Wagner turbidimeter method. The last two methods measure the surface area, whereas the first measures
