Apparatus Required
- 90-micron sieve
- Weigh balance
- Tray
The procedure of the test
- Weigh accurately 100gms of Cement in a tray.
- Place on a standard IS Sieve 90 microns, breaking down any air set lumps in cement samples if any.
- Continuously sieving the sample by holding the sieve in both hands with gentle wrist motion for a period of 15 minutes continuously with the underside of the sieve should be lightly brushed with a small brush after every 5 minutes of sieving.
- Weigh the residue retained on a 90-micron sieve after 15 minutes of sieving.
- Calculate the percentage of fineness – weight retained on 90micron sieve divided by the weight of total cement taken for the test.
