FINNESS OF CEMENT TEST BY DRY SIEVE METHOD
FINNESS OF CEMENT TEST BY DRY SIEVE as per IS 4031 Part - 1 1. Scope : This procedure covers the test method for determining the fineness of cement by dry sieving as represented by the mass of residue left on a standard 90 micron IS Sieve. 2. APPARATUS : Sieve - 90 micron IS Sieve Balance - Balance - The balance shall be accurate to 0.1 percent of the weight of the test sample. Brush - A nylon or pure bristle brush, preferably with 25 to 40 mm bristle, for cleaning the sieve. 3. Test Procedure : Weigh accurately 100gm of cement (Wc) and place it on a 90 micron IS sieve. Break down any air lumps in a sample with fingers without rubbing them on sieve. Place it on the sieve, being careful to avoid loss. Disperse any agglomerates. Fit the lid over the sieve. Continuously sieve sample by holding the sieve in both hand & Giving wrist motion until no more fine material passes through it. Weight the residue left on the sieve after sieving as (W1). Repeat the procedure for second sampl...
