DETERMINATION OF FINE NESS OF CEMENT BY SIEVING
Aim: To determine fineness of cement sample.
Scope: This procedure covers all relative activity for the project site.
- Weight accurately 100 gm of cement (W1) and place it on a standard IS sieve 90 microns.
- Break down the air set lumps in the sample with finger.
- Continuously sieve the sample given circular & vertical motion for a period of 15 minutes. Mechanical sieving devices may also be used.
- Weight the residue left on the sieve (W2) .This weight shall not exceed 10% for ordinary cement.
Fineness of Cement (%) = W2/W1 x 100
