Fineness • Fineness, or particle size of Portland cement affects Hydration rate and thus the rate of strength gain, The smaller the particle size, the greater the surface area-to- volume ratio, and thus, the more area available for water- cement interaction per unit volume, The effects of greater fineness on strength are generally seen during the first seven days. When the cement

23.10.2015 FINENESS So we need to determine the fineness of cement by dry sieving as per IS: 4031 (Part 1) – 1996.The 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 Sieve, Balance capable of weighing 10g to the nearest 10mg, A nylon or pure bristle brush, preferably with 25

by grinding the cement to a very high fineness: 7000 to 9000 cm. 2/g. Because of this, the gypsum content has to be higher (4 percent expressed as SO3). Because of its high fineness, it has a low bulk density. High fineness leads to rapid hydration, and therefore to a high rate of heat generation at early ages and to a rapid strength development ( 7 days strength of rapid

Fineness of Cement - Civil Engineering

Importance of Cement Fineness. The fineness of cement affects hydration rate, and in turn, the strength. Increasing fineness causes an increased rate of hydration, high strength, and high heat generation. 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

What Is Fineness Of Cement? - Importance Test Procedure

Fineness of cement = (W2/W1) x 100. The test has to be done with at least three samples from the same batch. The average value is the fineness of the cement. The ratio between the test samples should not be greater than 0.2% if else then repeat the test. The retaining cement particles in sieve should not be more than 10%.
