Nov 03 2017 · 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 µmGet A Quote
of retained weight of cement 651000 x 100 SO the result of a fineness test of cement will be 65 which is below the IS value 10 and hence cement is in good condition Thanks for reading this article Please don’t forget to share itGet A Quote
The fineness of cement is controlled by a minimum specific surface area defined as the surface area of cement particles per gram of cement For ordinary Portland cement the specific surface area should not be less than 2250 centimeter square per gramGet A Quote
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 isGet A Quote

Fineness of Cement The size of the particles of the cement is its fineness The required fineness of good cement is achieved through grinding the clinker in the last step of cement production process As hydration rate of cement is directly related to the cement particle size fineness of cementGet A Quote
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 SieveGet A Quote
Jun 18 2014 · Coarse cement particles settle down in concrete which causes bleeding Approximately 95 of cement particles are smaller than 45 micrometers with the average particle around 15 micrometers In the early 1900s cement fineness was expressed as the mass of cement per fractional size percent weight retained on specific sieve sizesGet A Quote
Mar 06 2020 · Fineness of cement increases with the increase of grade Grade of cement is chosen as per the one requirement and type of work Different grades of Cement No matter whats the brand of cement is There are three different grades of Ordinary Portland cement which are available in the market 33 Grade 43 Grade 53 Grade 33 Grade of CementGet A Quote
Finer cement deteriorates more quickly when exposed to air and likely to cause more shrinkage but less prone to bleeding The fineness of cement is controlled by a minimum specific surface area defined as the surface area of cement particles per gram of cementGet A Quote
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 The residue is then weighed and this weight should not be more than 10 per cent of original weightGet A Quote
