Test To Check Fineness Of Cement. FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size.
Fineness test indirectly measures the surface area of the particles of cement per unit mass. 5. Fineness increases the strength development in the cement principally during its first seven days. 6. It increases the rate of hydration. More is the fineness of cement particles more will be the rate of hydration. Apparatus. 1. IS Sieve (90 µm ...

1.1 This standard (Part 1) covers the procedure for determining the fineness of cement by dry sieving as represented by the mass of residue left on a standard 90 w IS Sieve. 2 REFERENCES 2.1 The following Indian Standards are necessary adjuncts to this standard: IS No. 460 ( Part 1 ) : 1985 ( Part 3 ) : 1985
What Is Fineness of Cement. The fineness of cement is a measure of cement particle size and is denoted as terms of the specific surface area of cement.. The Fineness Test of Cement is done by sieving cement sample through standard IS sieve. The weight cement particle whose size greater than 90 microns is determined and the percentage of retained cement …
This test is conducted to find the setting times of cement using a standard consistency test apparatus, Vicat's apparatus. Standard consistency of cement paste is defined as that water content which will permit a Vicat plunger of 10 mm diameter and 50 mm length to penetrate depths of 33-35 mm within 3-5 minutes of mixing.
Excessive fine cement requires more water for hydration, resulting reduced strength and durability. Fineness of cement affects properties like gypsum requirement, workability of fresh concrete & long term behavior of structure. Coarse cement particles settle down in concrete which causes bleeding. Test Standard Reference
The fineness 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 the determination of the weight of the cement particles whose size is greater than 90 microns and thus the percentage retained is computed.
1 Test Fineness of Cement by Sieve Analysis Method THEORY& IMPORTANCE This experiment is carried out to check the proper grinding of cement. The cement which is produced by an industry is checked for its quality, that either it is good for certain type of construction or it doesn't possess that much strength.
What is fineness test of cement? The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement.
Fig 1: Fineness of cement test apparatus. Procedure to Determine Fineness of Cement. Stir the sample of cement to be tested by shaking for 2 minutes in a stoppered jar to disperse lumps. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout the cement.
The following 8 Types of cement test are usually conducted in the laboratory, this is also known as a physical test of cement: 1. Fineness Test. 2. Normal consistency test. 3. Initial and final setting time test. 4. Soundness test. 5. Compressive Strength Test. 6. Chemical composition test. 7. The heat of hydration test. 8. Tensile Strenght ...
1. The fineness of a given sample of cement is _ _ _ _ % 2. Report the value of R, to the nearest 0.1 percent, as the residue on the 90 micron sieve for the cement tested. The standard deviation of the repeatability is about 0.2 percent and of the reproducibility is about 0.3 percent. 6.Video Fineness of Cement
How to Check Quality of cement on Site Fineness test of Cement:-As per IS: 4031 (Part 1) – 1996. The cement of good quality should have less than 10% of wt of cement particles larger than 90 µm. (micron) To determine the number of cement particles larger than 90 µm. or Fineness test of cement. The following apparatus is used.
