Test To Check Fineness Of Cement ... Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest 0.01g and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.
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 cement?

WT-23ESB Fineness Test Sieve is a one-piece brass frame with No. 325 stainless steel wire cloth. The 2in (50.8mm) dia. the frame is 3in (76.2mm) deep from rim to cloth and can be verified to ASTM E11 Calibration or Inspection Grade. User-calibration is required with BS-50 No. 114 NIST Portland Cement.
The fineness of cement has an important bearing on the rate of hydration and hence onthe rate of gain of strength and also on the rate of evolution of heat. Finer cement offers agreater surface ...
Oct 17, 2017· 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.
Apr 12, 2020· Blaine air permeability test of cement. 2. Wagner's turbidimeter test. 3. Particle size distribution method. 4. Lea & nurses air permeability test of cement. Blaine air permeability test of cement. Aim: To determine the fineness of cement by determining specific surface by Blaine's air permeability method (IS 4031 – 1958).

Nov 27, 2015· Cement fineness test procedure by sieving 90 micron as per IS 4031, Quality control test for cement - Duration: 7:48. Constructiontest org .
A Minimum quantity of water required to initiate the chemical reaction between water and cement to form a paste is known as consistency of cement. By Standardising the consistency of cement, we know that how much of water is required to produce an effective cement which will eventually produce good quality of concrete.
Jun 18, 2014· In the early 1900s, cement fineness was expressed as the mass of cement per fractional size (percent weight retained on specific sieve sizes). Now a day's fineness is usually measured by the Blaine air-permeability test that indirectly measures the surface area of the cement .

Aug 01, 1970· 6. For concrete containing no entrained air, there is a slight decrease in the static modulus of elasticity at 28 days' age as the fineness is increased. The modulus of elasticity of concrete determined by sonic methods decreases as the fineness of the cement increases. 7. The fineness of cement influences the drying shrinkage of concrete.
Total weight of residue = w 2 = 13.4 gram % age of fineness = 86.6 %. COMMENTS: "The fineness of cement is not according to the ASTM standard, so the cement is not perfectly fresh therefore it should not be used for making concrete .
> Cement Tests > Portland Cement Fineness. Portland Cement Fineness. Fineness, or particle size of portland cement affects hydration rate and thus the rate of strength gain. The smaller the particle size, the greater the surface area-to-volume ratio, and thus, the more area available for water-cement .
The Fineness Modulus (FM) 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.Sieves .
