2020-7-21The admixture dosages reduced considerably as fineness of sand increases as shown in Figure 2. The Figure 2 shows that Admixture Dosage reduced from 1.0 percent to 0.2 percent as sand fineness modulus increases from 2.0 to 3.0. For Every 5 increase in FM of sand, admixture dosage reduced by 0.1. Effect of Fineness of Sand on Density of Concrete.

This is the degree of coarse of sand. It is measured by 2 major ways cutting a thin section of the grain and measuring its diameter or by passing sample through a series of graded seives. For the latter, it involves a stack of up to 10 grades of.

Fineness modulus of sand fine aggregate is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness.

2017-7-6It is pointed out that manufactured sand is anytime better than river sand. The particle shape is cubical, which is almost closer to rounded river sand. Another issue associated with river sand is that of obtaining required grading with a fineness modulus FM of 2.4 to 3.1. Generally FM of 2.2 to 2.6, 2.6 to.

Initially, a Mortar Grinder was used for this task 20 g quartz sand is ground analytically fine with the Mortar Grinder PULVERISETTE 2 with agate bowl in 30 minutes. But in only 5 minutes, 100 g of quartz sand is ground to a comparable analytical fineness by using the Planetary Mono Mill PULVERISETTE 6 classic line , with a 250 ml agate grinding bowl and 15 agate balls with 20 mm diameter.

3- There are some high-quality desert sands that can be used in construction. However, extra fineness may be a problem in the workability but advantageous instability and cohesion 4- You can use it if you mix it with other sizes to bring the mixture within the acceptable limits.

10. A very coarse cement under some conditions can cause a serious bleeding problem on some construction projects. 11. When a cement is used that meets the present Federal specifications, it is doubtful that a field construction problem could be greatly influenced by changing the cement fineness.

Fineness modulus of sand is an index arrived based on the particle size analysis and then dividing the sum of the cumulative percentage of particles retained on the sieves by 100. it is important to note that higher the fineness modulus, higher is the coarser portion of the sand.
