Aug 08, 2017· 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 the following sieve numbers are recommended by ASTM. Cement by wet process = # 300 sieve Cement by dry process = # 200 sieve 3.
The fineness of cement influences the drying shrinkage of concrete. When the water content is increased because of fineness, the drying shrinkage is increased. However, if excessive bleeding due to coarseness of the cement takes place, a reduction in the drying shrinkage occurs. 8. The resistance of airentrained concrete to deterioration ...

Oct 17, 2017· 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 mesh size is thus determined. APPARATUS: 1) 90μm IS Sieve 2).
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 .
Abstract. This test method covers hydraulic cement fineness tests performed using a sieve. The sieve frame should be made of a circular metal matching the specified dimensions, fitted with either a stainless steel wovenwire sieve cloth or an electroformed forced nickel sieve sheet.

offers 134 cement fineness sieve analysis test products. About 26% of these are testing equipment, 2% are vibrating screen. A wide variety of cement fineness sieve analysis test options are available to you, such as free samples.
Sieve shown in pic below is not the actual 90µm just for reference. Procedure to determine fineness of cement i) Weigh approximately 10g of cement to the nearest and place it on the sieve. ii) Agitate the sieve by swirling, planetary and linear movements, until no more fine material passes through it.
for 8 X 8 X 16 inch. Concrete block, of % core space, made on a power tamping block machine at a yield of to block per bag of cement. The aggregate was blended from fine (No. 4 to 0) and coarse (3/8 inch to No. 4) materials in proportions to yield the desired fineness modulus. It should be noted that the strengths given in Fig. 2

The size of the particles of the cement is its required fineness of good cement is achieved through grinding the clinker in the last step of cement production hydration rate of cement is directly related to the cement particle size, fineness of cement is very important.
However, in this article, we''ll only discuss about the sieving method of determining the Fineness of Cement. Because this is the most common and easiest method to test fineness of cement. As per Indian Standard, the cement particle more than 10% shall not retain on the sieve (90 µm).
