2. Increasing the fineness of cement from 2700 to about 4000 cm2/g reduces the water requirement of concrete. Increasing the fineness of cement beyond an optimum limit increases the water requirement of concrete. 3. The workability of non airentrained concrete is increased by increasing the cement fineness. In airentrained concrete the effect ...

Dec 16, 2017· Soundness test of cement: The change in volume of cement after setting or hardening is caused due to the "unsoundness of cement." The expansion of cement after setting causes disruption of the hardened mass and create severe difficulties concerning strength and durability of the structure.
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.
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 ...
B. Fineness Modulus Purpose of Procedure The fineness modulus is an indicator of the fineness of the fine aggregate. As the fineness modulus increases the material will tend to be coarser. The fineness modulus is also used to monitor the uniformity of the fine aggregates. For the purposes of this test fine aggregate is defined as that material
Test the Fineness of Cement By Sieve Analysis Method. June 2, 2012. Engineering 0. 49099. 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 posses that much strength.
Really thankfull for explaing the testing the fineness testing of cement by sieve method, Can you please tell the acceptable limits as per CPWD specifications or civil engineering of fineness of cement using the sieve method Is there any corelation between the results obtained by the sieve method and the results obtained by Blains method

Fineness of cement is the direct indication of its particle size. Generally, it is measured on a scale of 1–10. Lower the fineness of the cement / aggregate finer is the particle size. And finer the particle size, greater will be the surface area ...
Chapter 12Testing of Cement – Part 1 page 61 A bed of cement is prepared in special permeability cell and have exact porosity e = 0,500 weight a quantity of cement. The weight of the cement is calculated from where ρ is the density of the cement [] V volume of the cement .
Cement fineness play a major role in controlling concrete properties. Fineness of cement affects the place ability, workability, and water content of a concrete mixture much like the amount of cement used in concrete does. Test Method: IS: 4031 (P2)1990. Heat of Hydration: When cement is mixed with water, heat is liberated.
It is an indirect test of fineness of cement. What is fineness? Cement is in the form of powder, which is obtained by grinding the various raw materials after calcimining. The grinding produces finer particles of cement. The degree to which the cement is ground to smaller and smaller particles is called fineness of cement
Fineness Test on Cement Fineness of cement particles may be determined either by sieve test or by permeability apparatus test. In sieve test, the cement weighing 100 gm is taken and it is continuously passed for 15 minutes through standard BIS sieve no. 9.
retests of the reference portland cement. Q: ASTM requires reporting values of total alkalies, fineness, and potential compound composition for the reference portland cement used for SAI testing. Can I use the values provided with the common reference portland cement? A: Yes, these values can be used as long as the common reference cement
Nov 24, 2017· consistancy,initial final setting time test of cement in Hindi Duration: ... Cement fineness test procedure by sieving 90 micron as per IS ... Determination Of Shrinkage Limit Duration: 14 ...
C430 Test Method for Fineness of Hydraulic Cement by the 45 ... Request Quotation. LAB II: CEMENT TEST Test 1.

Aug 08, 2017· 7 Discussion By this experiment we know the grinding or fineness of cement and its useful to checked the strength of cement by rate of fineness, standard range of cement for use it must be greater than 90% if its smaller than this range it can''t use, we do this test three times and get average result, without errors result must be don''t ...
Nov 03, 2017· 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.
Fineness Test Sieve consists of a onepiece brass frame and stainless steel wire cloth. Calibration is verified in accordance with ASTM and AASHTO standards with use of BS50 NIST Portland Cement. 2in TwoPiece NickelPlated Wet Wash Sieve Frame is used with No. 325 Mesh disc in performing fineness test.
Blaine Air, Fineness, continued Two test methods are given: test method A is the reference test method using the manually operated standard Blaine apparatus, while test method B permits the use of an automated apparatus, which has demonstrated acceptable performance.
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 airpermeability test that indirectly measures the surface area of the cement .
