Jun 01, 2012· The number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement, following number sieve is recommended by ASTM. Cement by wet process = # 300 sieve. Cement by dry process = # 200 sieve.

MoreJul 08, 2017· Fineness of Cement is measured by sieving cement on standard sieve. The proportion of cement of which the cement particle sizes are greater than the 90 micron is determined.

MoreFeb 11, 2019· 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. Sieving Method. 2. Air Permeability Method (Blaine Method).

MoreFeb 02, 2018· 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.

MoreSieve shown in pic below is not the actual 90µm seive.Its just for reference. 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.

MoreSieve Analysis Aggregate gradation (sieve analysis) is the distribution of particle sizes expressed as a percent of the total dry weight. Gradation is determined by passing the material through a series of sieves stacked with progressively smaller openings from top to bottom and weighing the material retained on each sieve.

MoreThe cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus. Fine aggregate means the aggregate which passes through 4.75mm sieve. To find the fineness modulus of fine aggregate we need sieve sizes of 4.75mm, 2.36mm, 1.18mm, 0.6mm, 0.3mm and 0.15mm. Fineness modulus of finer aggregate is lower

MoreJan 29, 2019· Fineness can be calculated from particle size analysis (sieve analysis) or by using air permeability method or by using sedimentation method. Sieve analysis measures the cement particle size whereas air permeability method & sedimentation method measures specific surface area.

MoreEffects of cement fineness on cement properties. Q. How does the fineness to which the clinker is ground affect the properties of the cement? A. Increasing the fineness increases the rate of hydration of cement, which increases the rate of gain in strength and also the rate at which heat is liberated as in Type III compared with Type I cement (ASTM C150).

MoreOct 19, 2020· 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. Apparatus. i) 90μm IS Sieve.

MoreSieve shown in pic below is not the actual 90µm seive.Its just for reference. 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.

MoreThe 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 cement is very important. Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength

MoreFineness modulus is determined using percentages of the size fractions from the sieve analysis and calculated for any designated series of sieve sizes. When designing concrete mixes, the FM of the fine aggregate is required for the effective proportioning of mixes.

MoreASTM C 430: Fineness of Hydraulic Cement by the 45-mm (No. 325) Sieve. In sieving test, a sample of having 100mg is taken and it is continuously passing for 15 minutes through standard BIS sieve no. 9.

MoreTYPES OF SEIVES: There are different types of sieves such as # 10, # 100,# 200,# 300 etc. the number of the sieve indicates the number of holed present in a linear inch of that sieve. For finding the fineness of Wet or Dry cement following number sieve is recommended by ASTM. Cement by wet process = # 300 sieve Cement by dry process = # 200 sieve

MoreFineness test of cement is performed to check the fineness of cement according to standard specifications. The fineness of cement can be measured either by the grain size of cement or by the surface area of cement. Followings methods are used to determine the fineness of cement. The sieve Test- Measures a grain size of cement.

MoreSep 01, 2014· Following procedure is adopted to calculate fineness modulus of aggregate. Procedure Sieve the aggregate using the appropriate sieves (80 mm, 40 mm, 20 mm, 10 mm, 4.75 mm, 2.36 mm, 1.18 mm, 600 micron, 300 micron & 150 micron)

MoreFor any type of mix proportioning sieve analysis results and fineness modulus is required. here is the excel sheet which includes calculations of fineness modulus. Hope it will consume less time in case of repetitive calculations. Excel Sheet For Sieve Analysis Of Aggregate And To Calculate Fineness Modulus- engineeringcivil

More9 Procedure To check if the less than 0.1% passed the sieve, do the following: a. Hold the sieve in slightly inclined position over a white clean and dry paper. b. Strike the side of the sieve with the palm in an upward stroke at the rate of 25 strokes per 10 seconds for a total of 150 strokes per 1 minute. Remember to rotate the sieve about 60 degrees on its plane for every 10 seconds.

MoreSieve Analysis.As we know that the Fineness modulus is a measurement of the coarseness or fineness of a given aggregate, higher the FM the coarser the aggregate. The above table is showing us that the Laurence pure sand is coarser then Chenab sand
