Sep 02, 2017· Quality of Sand on Site:Sand is one of the important constituents of concrete. The main purpose of mixing sand (fine aggregate) in concrete is to fill the voids between Coarse aggregate. And the voids between fine aggregate is filled with cement. Sand bulks the concrete and helps to increase the workability of concrete.

Braen Stone has washed concrete sand for sale at the best prices across northern NJ. As the largest supplier of washed concrete sand in New Jersey and New York we offer concrete sand for bulk delivery by the ton to all of NJ, NY, NYC and PA.
Jun 25, 2014· Importance in terms of Workability. A workable concrete can be achieved by adding more water, but as we know the more water present in concrete the poor strength it gives. The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete.
Concrete is contains 70% aggregates by volume. So understanding properties and function of aggregates plays an important role in determining the strength of concrete. Here is a detail on various properties, functions, characteristics and significance of Aggregates used in Concrete
The net cost of Concrete reduces when FM of sand increases. It reduces by about % for an increase of FM from to As the fineness modulus of Sand increases, the Cost/Benefit Ratio reduce by a very large factor. This is 29% when FM changes from to That means we can get large advantage by using concrete having Coarse Sand.
Fine Sand for Use in PC Concrete Final Report for MLR886 March 1989 Highway Divisiont:~,ofTransportation. Fine Sand For Use In Concrete Final Report MLR886 Kevi n Jones Cement and Concrete Engineer Office of Materials Iowa Department of Transportation ... number 30 sieve is required for the sand.
Apr 12, 2018· A typical concrete mix contains 60 to 80 percent sand and gravel, also known as an "aggregate." This aggregate compound is more than filler. It plays an important part in the concrete''s composition. The amount of sand and gravel in a bag of concrete determines the .
The premise: "aggregate of the same fineness modulus will require the same quantity of water to produce a mix of the same consistnecy and give a concrete of the same strength." Before calculating FM, lab technicians perform a sieve analysis to determine the particle size distribution, or grading, of the aggregate sample.
Sep 01, 2014· What is Fineness Modulus of Aggregate? Fineness modulus is an empirical factor obtained by adding the cumulative percentages of aggregate retained on each of the standard sieves ranging from 80 mm to 150 micron and dividing this sum by 100. Why to Determine Fineness Modulus? Fineness modulus is generally used to get an idea of [.]
Attach a pan under the sieve to collect the cement passing the sieve. Weigh approximately 10 g of cement to the nearest g and place it on the sieve. Fit the lid over the sieve. Shake the sieve by swirling, planetary and linear movement until no more fine material passes through it. .
Dec 01, 2014· A In the case of manufactured sand, if the material finer than the No. 200 sieve consists of the dust of fracture, essentially free of clay or shale, these limits are permitted to be increased to 5 and 7%, respectively.. The soundness of fine aggregates can be determined by subjecting the material to five cycles of the soundness test. The weighted average loss cannot be greater than 10% when ...
The important characteristics of aggregates for concrete are listed in Table 52 and most are discussed in the following section: Grading. Grading is the particlesize distribution of an aggregate as determined by a sieve analysis (ASTM C 136 or AASHTO. 80. Design and Control of Concrete Mixtures EB001. Table 51. Rock and Mineral Constituents ...
Mar 27, 2016· What Is Concrete And Why It Is So Incredibly Important? Concrete is an artificial stonelike material that is used in various building structures. It is very inexpensive and strong, being essential for stability in any construction. It also is very easy to make .
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 ...

and recorded cumulatively. (Note: In a ! ne aggregate sieve analysis, the test sample is washed over the No. 200 (75 µm) sieve and the portion retained on the No. 200 (75 µm) sieve is dried and the loss recorded.) Sieve Analysis Example The following sieve analysis is for a sample of natural sand for use in concrete Sieve! " # % ''
representative of the material as a 25 lb sample of natural sand. TWO IMPORTANT DEFINITIONS TO REMEMBER Top Size or Maximum Particle SizeThe sieve on which 100 percent of the material will pass. Nominal Maximum Particle SizeSmallest sieve opening through which the entire amount of the aggregate is permitted to pass.

concrete sand sieve analysis. Coarse Aggregate Sieve Analysis Calculators. ... Sieve analysis is important for analyzing materials because particle size distribution can affect a wide range of properties such as the strength of concrete, the solubility of a mixture, surface area properties and even their taste.
Jun 02, 2012· Importance: This experiment is carried out to find and check the gradation of the fine aggregate sand. The concrete consists of three basic solid materials, one is the sand whose fineness is checked by experiment , the other two materials are the coarse aggregate that is the crush while the third is the fine aggregate that is the sand.
