z Don't Miss a Chance to Connect With Experts. A well graded soil is able to be compacted more than a poorly graded soil. Sir please can you recomend me BSC civil engingineering PRC an structural mechanics books please? Minimum of 300-g fine and 5-keg coarse aggregates are obtained. It also helps determine what modifications can be applied to the soil and the best way to achieve maximum soil strength. The sample is placed in top sieve. The mass of each size increment is determined on balance. When it comes to wet sieving it is very important not to change the sample in its volume (no swelling, dissolving or reaction with the liquid). W t What is Scaffolding? Coarse aggregate coefficient of uniformity is very small and did not exceed 4. The results of this test are used to describe the properties of the aggregate and to see if it is appropriate for various civil engineering purposes such as selecting the appropriate aggregate for concrete mixes and asphalt mixes as well as sizing of water production well screens. Higher  the value of FM ,coarser will be the aggregate. 3. The entire nest is then agitated, and the material whose diameter is smaller than the mesh opening pass through the sieves. There are some limiting values for every sieve provided by ASTM or BS, we use these limiting values to get our final answer by the method explained below. TITLE : SIEVE ANALYSIS. Coefficient of gradation is only one criterion in grading aggregates. This parameter (also called as coefficient Of curvature) can be expressed as: where; DISC, 030, and DID the particle-size diameters corresponding to 10, 30, and 60 respectively, passing on the cumulative particle-size distribution curve. Note that if the entire stack of sieves does not fit into the shaker, perform a hand shaking operation until the top few sieves can be removed from the stack and then place the remained of the stack in the mechanical shaker. At Paperap.com you will find a wide variety of top-notch essay and term paper samples on any possible topics absolutely for free. The first is to break up the lumps with a rubber-tipped pestle in a ceramic mortar. Q.2: What is meant by the size of a sieve or number of the sieve? Lab Exercise 5. Nodules of lumps of soil must be broken down into their individual particles in order for the grain size analysis to be valid. Classification. The total mass of the material after sieving should check closely with original mass of sample placed on the sieves. [CDATA[ No problem! e Compute the percent retained on each sieve by dividing the weight retained on each sieve by the original sample weight. As surface area is inversely proportional to fineness modulus so Chenab sand will be having the greater surface area of all the samples as its fineness modulus is least that is 1.492. Sieve analysis is an analytical technique used to determine the particle size distribution of a granular material with macroscopic granular sizes. L Fine aggregates is mostly sand Which passes NO. Sum these weights and compare with the actual weight taken. 3. T The column is typically placed in a mechanical shaker. For example, foundations might only call for coarse aggregates, and therefore an open gradation is needed. Place the stack of sieves in the mechanical sieves shaker and sieve for 5 to 10 minutes. Calculate coefficient of uniformity and curvature and classify aggregates into well graded or poorly graded aggregates based on given criteria or these two parameters. Don't use plagiarized sources. For course aggregates, the sample is split into two or more batches, sieving each batch individually. At the base is a round pan, called the receiver. It's Free!

Gradation is determined by passing the material through a series of sieves stacked with progressively smaller openings from top to bottom and weighing the material retained on each sieve. ×100%. Yes you can download anything after being a member All the content of this paper is his own research and point of view on Sieve Analysis Of Fine Aggregate Lab Report Conclusion and can be used only as an alternative perspective. %Cumulative Passing = 100% - %Cumulative Retained. A large quantity sample required longer shaking than a smaller sample. Now take these minimum and maximum value lines as your reference and if the curve of our own data lies inside these two lines then the quality of our sample is OK but if your curve lies outside these two lines of maximum and minimum range then the sample is not according to specifications.
