MoreFineness of cement is tested in two ways : (a) By sieving. (b) By determination of specific surface (total surface area of all the particles in one gram of cement) by air-permeability apparatus. Expressed as cm 2 /gm or m 2 /kg. Generally Blaine Air permeability apparatus is used. 2. Apparatus Required Fig. 2: Cement

MoreFineness 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.

MoreExperiment 1: Fineness of Hydraulic Cement Discussion and Elaboration: The experiment was conducted to measure the fineness of the sample cement after sieving in a certain period. For the experiment, the researchers used Type 1P Eagle Cement. As indicated in the procedures, the cement was sieved with the use of a #200 sieve. The primary function of the instrument is to aid the

More27-03-2020 Procedure of Fineness Test of Cement by Sieve Analysis:-. Agitate the representative sample of the cement to be tested by shaking for 2 minutes in a stoppered jar to disperse agglomerates (lumps).Wait for 2 minutes and stir the resulting cement powder gently using a clean dry rod in order to distribute the fines throughout the cement.

MoreFineness test indirectly measures the surface area of the particles of cement per unit mass. 5. Fineness increases the strength development in the cement principally during its first seven days. 6. It increases the rate of hydration. More is the fineness of cement particles more will be the rate of hydration.

MoreFineness 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%.

More17-10-2017 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.

MoreCalculation. Ravg = (R 1 +R 2 +R 3) / 3 Fineness modulus of cement = Ravg / 100 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.
