The fineness of cement is a measure of the size of particles of cement and is expressed in terms of specific surface area of cement. Fineness can be calculated from
The Fineness modulus of cement is an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series of sieves, and dividing the sum by 100. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Contents:Fineness Modulus []
In permeability apparatus test, specific surface area of cement particles is calculated. This test is better than sieve test and it gives an idea of uniformity of fineness. The specific surface acts as a measure of the frequency of particles of age size. The specific surface of cement should not be less than 2250 cm2/gm.

The test used for determining soundness of cement is known as "Le chatelier apparatus test." By soundness of cement, it is understood that, its capacity to form a nondisintegrating, hard uniformly strong mass on the setting. This depends on its original composition, proper burning, and grinding. Presence of lime in the free state, an excess of sulfate or magnesia and a very fine size may
Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass. FINENESS LIMIT: It should not exceed the following percentage by weight for different types of cement. Ordinary Portland cement =10%; Rapid hardening cement =5%; Low heat cement =5% ←
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 particle are calculated. This is known as Fineness of cement.

Fineness 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 % if else then repeat the test. The retaining cement particles in sieve should not be more than 10%.

Test To Check Fineness Of Cement Posted in Civil Engineering Tests | Email This Post | FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – principle of this is that we determine the proportion of cement whose grain size is larger then specified mesh size. The apparatus used are 90µm IS Sieve, Balance capable of weighing 10g to the
IS 4031(Part 1):1996 Methods of Physical Tests for Hydraulic Cement: Determination of Fineness by Dry Sieving (second revision). Reaffirmed May 2016 4. procedure. Agitate the sample of cement to be tested by shaking for 2 min in a stoppered jar to disperse agglomerates. Wait 2 min. Stir the resulting powder gently using a clean dry rod in
Test for fineness of cement is carried out for proper grinding of cement and to measure the mean size of the grains in it. METHOD OF TESTING FINENESS OF CEMENT : Sieve Analysis Method. Weighing a 100 g of cement with accuracy of g as a sample and if any airset lumps present in the sample are broken with finger. The sample is placed on a 90 micron sieve and continuously sieved for 15
1. Fineness Test. Fineness is the mean size of cement grain. It is done to measure the mean size of cement grain. The finer the cement the surface area for hydration will be large and it increases the strength of cement. But the fineness varies in different types of cement. One of the Following three methods can be applied to test the fineness
Fineness Test of Cement. AASHTO T 98 and ASTM C 115: Fineness of Portland Cement by the Turbidimeter. AASHTO T 128 and ASTM C 184: Fineness of Hydraulic Cement by the 150mm () and 75mm (No. 200) Sieves; AASHTO T 153 and ASTM C 204: Fineness of Hydraulic Cement by AirPermeability Apparatus o AASHTO T 192 and
· Fineness Test of Cement. February 2, 2018 October 3, 2018 by Kathir Leave a Comment. Aim. To determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996. Principle. The fineness of cement is measured by sieving it through a standard sieve. The proportion of cement, the grain sizes of which, is larger than the specified mesh size is thus determined.
Chapter 12Testing of Cement – Part 1 page 59 12. TESTING OF CEMENT – PART 1. Density The density is the fundamental physical characteristic of the material. Density is defined by mass of a unit volume of a material substance, expressed as kilograms per cubic metre. where ρ is density in () m mass of the material sample in kg (g) Vh volume of the specimen in m 3 (cm 3
Fineness Test On Cement The Construction Civil. Fineness Test on Cement. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9. The residue. read the rest
Fineness test of cement is done to determine the particle size of cement. As, the rule of thumb, the finer the cement particle the best will be the cement and on the other hand the coarser the particle it will not be that good. The fineness of cement is determined by two methods; 1.
LAB II: CEMENT TEST Test 1. Cement fineness test (ASTM C 184 94) Procedures Place 50 g sample of cement on a clean and dry # 100 (hole size of Request Quotation. Test To Check Fineness Of Cement – Civil Engineering Portal. FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) Request Quotation
Soundness Test of Cement What is soundness of cement? The ability of cement to retain its volume after it gets hardened is known as Soundness of Cement. That means the cement should be at minimum volume change after it gets hardened. The test conducted to identify the excess amount of lime in cement is known as soundness test of cement. Significance – Why are we calculating this value for
· Procedure for finding Fineness test of cement: Take a sample of cement and rub the cement with your hands. The test sample should be free of lumps. Now Take 100g of cement and note it as W1. Pour 100g of cement in 90 µm sieve and close it with the lid. Now place the sieve in Sieve shaking machine for two minutes. You can also shake the sieve with your hands by Agitating the sieve
The laboratory test are conducted based on the standards published by the Indian standard. The quality of cement is found by conducting the fines of cement. Which is conducted at certain test is performed unless otherwise having the temperature of 27+ or 2 0 C and 65+ or 5% of relative humidity of the laboratory.
· Aim: To determine the fineness of cement by Wagner''s turbidimeter test. Apparatus: Beaker, kerosene, light bulb, photoelectric cell. Procedure: Initially clean the beaker with a dry cloth. Then add kerosene in the beaker. Add cement in the beaker and stir it well. Due to which the turbidity of kerosene increases.
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. The maximum residue after the sieving in standard sieve should be limited to 10% by weight for OPC, and 5% by weight for rapid hardening cement. Why is fineness test of cement done?
