Apr 06, 2018· Bleeding can be reduced by increasing fineness. However, increased fineness can also lead to the requirement of more water for workability, resulting in a higher possibility of dry shrinkage. Fineness test is used to check the proper grinding of cement and measures the surface area of the cement particles per unit mass. FINENESS LIMIT:

Note 2: Keene''s cements are generally available as quicksetting and standardsetting types. However, various grades of gypsum Keene''s cement of different fineness and setting time are available. Grades intended for use in scagliola castings and other special purposes should conform to the requirements of this specification in all respects except fineness and setting time.
Fineness Standard EN 1966 describes two methods of determining the fineness of cement: sieving method air permeability method ( Blaine) Sieving Method This method serves only to demonstrate the presence of coarse cement particles. This method is primarily suited to checking and controlling production process.

Test To Check Fineness Of Cement ... 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.
In the present study, the rheology test was used to determine the influence of gypsum fineness in the first few hours of cement hydration. The analysis of the hydration and rheological behaviour of cement pastes with the addition of fine, medium, and coarse gypsum made it possible to measure the influence of gypsum fineness on the cement paste. 2.

1. Fineness test The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain of strength and also on the rate of evolution of heat. Finer cement offers a greater surface area for hydration and hence faster the development of strength, fig. below. Different cements are ground to different fineness.
Although the test method may be, and has been, used for the determination of the measures of fineness of various other materials, it should be understood that, in general, relative rather than absolute fineness values are obtained. This test method is known to work well for portland cements.
May 02, 2013· Overview Fineness of cement is measured by sieving it on standard sieve. The proportion of cement of which the grain sizes are larger than the specified mesh size is thus determined. Apparatus Measuring Instruments NAME CAPACITY / RANGE / SIZE ACCURACY / LEAST COUNT Sieve 90 micron mesh — Balance 10g (max.) 10 mg Supplementary accessories [.]
The presence of gypsum limits dispersion of soil colloids. In the traditional procedures for particlesize analysis of gypsiferous soils, gypsum present in small amounts is leached by using distilled water (Baldwin et al. 1938, Barzanji 1973). Solutions of strong electrolytes can be used to increase the solubility of gypsum and shorten the leaching time (Abrukova and Isayev 1983, Agboola and ...
The fineness of a given sample of cement is _ _ _ _ % 2. Report the value of R, to the nearest percent, as the residue on the 90 micron sieve for the cement tested. The standard deviation of the repeatability is about percent and of the reproducibility is about percent. Fineness of .
