4) High strength concrete was developed by using the same brand of cement available in market (having fineness value of 2975 cm2/g).Six trials were made to design the concrete mix. Concrete with water cement ratio, 0.28 and mix proportion of 1:0.75:1.75 with 1.7% by weight of cement super plasticizer was selected. 5) 6 concrete mixes were prepared by …
The fineness of cement refers to the particle size distribution of the powder and has a direct impact on the speed of hydration, the rate of strength development, and the ultimate strength of the hardened concrete. ...

FINENESS OF CEMENT The fineness of cement has an important bearing on the rate of hydration and hence on the rate of gain ... Gently brush all the fine material off the base …
Cement fineness plays a crucial role in defining the factors that influence strength and quality. Cement fineness influences and controls various cement properties. This includes the rate of evolution of heat, the rate of gain of strength, and the rate of hydration. The common value of the fineness of the cement is around 300–400 cm2/kg.
Fineness Test of Cement. Fineness 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 following proportions are usually maintained in Cement: About 10% of the cement of fine particles is smaller than 2 µm, 10% of wt of cement is made of particles larger than 50 µm, and only a few wt% is particles larger than 90 µm. ... The fineness of Cement Formula:-A good cement should retain 10% wt of cement when it is sieved …
Empty the pan and fix it below the sieve. Repeat the whole procedure, at least three times, using a fresh 100 g sample of cement. Totally sieve for 15 minutes and weigh the residue (weight of cement …
In concrete production, the use of concrete fine fraction waste made it possible to reduce cement consumption to obtain the same level of compressive strength. Regarding the waste processing, it was found that approximately 19% of crushed material was used in mechanical sifting, considering the material passing through sieve #100 …

A concrete mix ratio of 1:2:4 (Cement: Fine aggregate: Coarse aggregate) with water/cement ratio of 0.5 was used. The results reveal that an increase in the fineness of cement particle led to an ...
The results were then linked against the fineness modulus of the fine aggregates. Concrete compressive strength decreased as the fineness modulus of fine aggregates decreased. ... where cement ...
According to ASTM C618, the pozzolanic activity of CS is evaluated by 20 wt%. Thus, the maximum dosage of CS was set to be 20% in this work. Table 2 lists the compositions of mortar specimens. In this work, the mixtures containing different fineness and proportions of CS (i.e., 10, 15 and 20 wt% CS as cement replacement) were prepared.
The fineness of cement is defined as the particle size distribution of the cement particles. These play a pivotal role in determining its quality and performance in construction materials.

The mix ratio by weight for the control was cement: coarse aggregate: fine aggregate ... To characterize the overall coarseness or fineness of fine aggregate in this study, the fineness moduli (FM) of the fine aggregates …
What is fineness test of cement? The test done for finding the fineness of cement by sieving the cement on the standard IS sieve is called the fineness test of cement. The proportion of cement size greater than …
The fineness of cement is a measure of the size of cement particles and is expressed in terms of specific surface area of cement. As you may know, the final process of cement manufacturing is to grind …
Cement paste with fine graphite: (a) 7-day Nyquist plot, (b) 28-day Nyquist plot, and (c) frequency-dependent resistance. ... This study examined the effect of graphite fineness on the performance of cement paste to be used in self-sensing applications. Three graphite products of varying fineness were tested, and it was found that graphite ...
Explanation: Fineness Modulus: It is an index number which is roughly proportional to the average size of the particles in the aggregate. It is sum of cumulative percentage retained on the sieve of standard sizes: 150 μm, 300 μm, 600 μm, 1.18 mm, 2.36 mm, 4.75 mm, 10 mm, 12.5 mm, 20 mm, 40 mm and 80mm.; Higher fineness …
The fineness represents the particle size of cement. It should not be greater than 90-microns when sieved as per IS standard.
How the fineness of cement affects the quality of concrete and the concrete mix design? Answer: Cement is like a powder, a fine sand, its grains are not measurable by plain sight. They are uniform in size. The fineness of cement has an important bearing on the rate of hydration, gain of strength and on the rate of evolution of heat.
Reading time: 1 minute Fineness Modulus Method of Concrete Mix Design The index number, which describes the relative sizes of coarse and fine aggregates, is called as fineness modulus (FM).
