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. ... Precautions to be taken while performing sieve analysis: 1. The cement sample ...

The test is conducted on a sample of sieved mortar. The time at which cement begins to harden and lose its plasticity is called the initial setting time of cement. However, the final setting time begins when concrete loses its plasticity completely and hardens. According to ASTM C403M-16, the initial and final time of concrete can be determined ...

Take 400g of cement and place it in a tray or bowl. Now let us assume the standard consistency of cement is 26% and add the same percentage of water into the cement and mix it. Now mix thoroughly the cement paste within 3-5 minutes and the time taken for obtaining cement paste from which water is added is known as gauge time.

If the test result is not in range of acceptance criteria, then you should find the reason. There are many reasons behind it, i.e. cement may be very fine, some chemical properties might have changed due to any reason, there may be defect during a manufacturing process, cement might have absorbed moisture from the atmosphere, etc. In that case ...

Here we take 100g of cement sample for test. Therefore, W1 = 100g. Now, Let assume 5g of cement sample is retained on 90 micron IS sieve after the sieving process. Therefore, W2 = Weight of cement which is retained on sieve = 5g. Fineness % of cement = (W2/W1)*100 = (5/100)*100 = 5%. To eliminate the errors, repeat the process 3 times and take ...

Fineness of cement Definition. Fineness of cement is an important physical property of cement that defines the particle size and the surface area of cement particles. It is expressed in %age when determined as a modulus with sieving or units of cm2/gm or m2/kg in case when determine by Blaine air permeability apparatus.

The final setting of time is the time from the addition of water in cement to when the cement has completely lost its plasticity. During this period, the cement paste becomes a hard mass and reach its optimum strength. Initial and final setting time of cement test can be determined with a simple experiment using the Vicat apparatus.

Appartus used for fineness test of cement. Sieve method test procedure: Collect a sample of cement and rub with your hands. The Fineness test sample should be free of lumps. Take 100 gm of cement sample and note its weight as W1. Drop 100 gm of cement in 90 µm sieve and close it with the lid.

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

The proportion of cement size greater than 90 microns is considered as fineness cement. In other words, the fineness of the cement is the particle size of cement. The maximum residue after the sieving in standard sieve should be limited to 10% by weight for OPC, and 5% by weight for rapid hardening cement. Why is fineness test of cement done ...
