Sep 17, 2019·Sieve Analysisof Fine Aggregates – Introduction.Sieve analysisof fine aggregates is one of the most importanttestsperformed on-site. Aggregates are inert materials that are mixed with binding materials such ascementor lime for the manufacturing of mortar or concrete. It is also used as fillers in mortar and concrete. Aggregates size varies from several inches to the size of the smallest grain of …

Rotary Kiln
A rotary kiln is a device that supplies tremendous amounts of heat in order to change the chemical composition of an object.
Cement Mill
A cement mill is the equipment used to grind the hard, nodular clinker from the cement kiln into the fine grey powder that is cement.
Coal Mill
In coal-fired power plants coal mills are used to pulverize and dry to coal before it is blown into the power plant furnace.
Sand Maker
Sand maker is suitable for the crushing of soft, hard and extremely hard material and reshape of those products.
Put thecementin thesievecarefully and close thesievetightly. Start shaking thesievehorizontally, keep on shaking thesievefor 10 to 15 minutes regularly. After 15 minutes take the residue left in thesieve, put it in a pre-weighed plate and note the weight w 2 of the residue with the help of triple beam balance.
Finenesstestofcementis done to determine the particle size ofcement. As, the rule of thumb, the finer thecementparticle the best will be thecementand on the other hand the coarser the particle it will not be that good. The fineness ofcementis determined by two methods; 1.
Apr 12, 2020· First, take thecement sampleof 100 grams ‘W1’ Second, Then add thiscementin the 90 usieveand close thesievewith the cap. Third, thensievethecementsample for 15 min to 20 min in clockwise, anti-clockwise direction, forward and backward direction. Fourth, then record the weight of the retainedcementin thesieveas ‘W2’.
1.1 Thistestmethod covers the determination of the particle size distribution of fine and coarse aggregates bysieving. 1.2 Some specifications for aggregates which reference thistestmethod contain grading requirements including both coarse and fine fractions. Instructions are included forsieveanalysis of such aggregates.
Procedure to Determine Fineness ofCementStir the sample ofcementto betestedby shaking for 2 minutes in a stoppered jar to disperse lumps. Stir the resulting powder gently using a clean dry rod in order to distribute the fines throughout thecement. Attach a pan under thesieveto collect thecementpassing thesieve.
For particle size analysis, the test sieve remains a cost effective and precise measuring instrument for dry non-agglomerated particles. Test sieve analysis is widely used for quality control in many industries worldwide, the test sieve process is a simple and common practice to measure particles size and dry relatively free flowing materials.

Types ofSieves: There are different types ofsievessuch as # 10, # 100,# 200,# 300 etc. The number of thesieveindicates the number of holed present in a linear inch of thatsieve. For finding the fineness of Wet or Drycement, following numbersieveis recommended by ASTM.Cementby wet process = # 300sieve.Cementby dry process = # 200 ...
To determine the fineness ofcementby dry sieving as per IS: 4031 (Part 1) – 1996. Principle. The fineness ofcementis measured by sieving it through a standardsieve. The proportion ofcement, the grain sizes of which, is larger than the specified mesh size is thus determined. Apparatus. i) 90μm ISSieve.

Sieve test[IS: 4031 (Part 1)] It is not a moderntest. In thiscementis passed through 90-micronsieveand the residue left on thesieveshould not be more than 10 percent. Air permeabilitytest[IS: 4031 (Part 2)] Thistestis better thansieve testand gives an idea of uniformity of fineness.
The Fineness modulus ofcementis an empirical figure obtained by adding the total percentage of the sample of an aggregate retained on each of a specified series ofsieves, and dividing the sum by 100. The proportion ofcementof which the grain sizes are larger than the specified mesh size is thus determined. Contents:Fineness Modulus […]
Sieve: Size of 12.5 mm, 10 mm and 2.36 mm; The crushing mould is filled in three layers with aggregates. Then the weight (W1) of the aggregate in the crushing mould is noted. After that, the mould is placed in the compressiontestingmachine and loaded at gradually applied load …

TestProcedure – Fineness Modulus of Sand. Take thesievesand arrange them in descending order with the largestsieveon top. If mechanical shaker is using then put the orderedsievesin position and pour the sample in the topsieveand then close it withsieveplate.
The fineness of grinding is an important feature and one not properly determined by the standardsieve test; although three-quarters of thecementmay pass the 200-meshsieve, the bulk of it may be, and frequently is, too coarse for efficient work, especially if it is …
