contact usFineness of cement = (W2/W1) x 100. The test has to be done with at least three samples from the same batch. The average value is the fineness of the cement. The ratio between the test samples should not be greater than 0.2% if else then repeat the test. The retaining cement particles in sieve should not be more than 10%.
contact usFineness 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.
contact usConclusion 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%.
contact usWe know that cement hydrates with the presence of water. When cement is mixed with the water, a thin layer is formed around the particle. This layer grows bigger and makes cement particles to separate. Due to this, hydration process slows down. Th...
