As we know that Larger value of FM is preferred for fine aggregates & For a good fine aggregate, the FM should be between 2.3 and 3.1 So, we can conclude that the Laurence pure sand is a good fine aggregate as the fineness modulus of Laurence pure sand is in between the given range of a good fine aggregate. %%EOF
The value of FM will not change if we add non standard sieves in standard set of sieves. 137 0 obj

2:……Chenab Sand …… Sample weight = 1000g = 1kg, Cumulative Percentage Retained up to particle size 150μm = 149.2 4:……Margala Crush …… Sample weight = 4000g = 4kg, Cumulative Percentage Retained up to particle size 150μm = 287.6 Standard Reference: ASTM D 422 - Standard Test Method for Particle-Size Analysis of Soils . Simplified Sieve Analysis data (left), Particle Size Distribution Graph for Sieve Analysis (Right) 3 fHYDROMETER ANALYSIS: The first step for the analysis of the hydrometer data is the application of the meniscus correction to the actual hydrometer reading, but since this is not the meniscus correction is then assumed to be zero. The basic principles of sieve analysis and hydrometer ever analysis are briefly described in the following two sections. Plain & Reinforced Concrete Experiments 1, Quantitative Section : GMAT Sample Problem Solving Ability, Transportation, Highways, Tunnels & Roads Books, https://civilengineerspk.com/concrete-and-structures-books/. J@k�ḹxТQ�%hݪƪ��c���wX�}msbl/�m����ܿ����l��|�/���+�����;EP�{߮O��w�ɱ�. If a soil contains appreciable quantities of fine fractions in (less than 75 micron) wet analysis is done. 2.1 Sieve Analysis . Find from here OBSERVATION During the experiment, student observe that soil sample can classify using two methods: Sieve Analysis and Hydrometer Analysis.According to reference, a sieve analysis consists of shaking the soil sample through a set of sieves that have progressively smaller opening. Please Help I want to be a member of your site ..but I have not bank account .. Bank Account is not required. Particle Size Analysis II – Hydrometer Analysis ... At the conclusion of the experiment, pour the contents of the graduated cylinder through a pre-wetted 4φ sieve. For analysis of more silt and clay size fractions (i.e., 50–20, 20–10, 10–5, 5–2, 2–1, <1μ), this study showed no difference between the two methods. INTRODUCTION • The sieve analysis is generally applied to the soil fraction larger The set of sieves used for the process of sieve analysis can be designated as; Take 2 kg of the oven-dried sample. It is a single factor or an empirical number which we get from the results of sieve analysis. The above table is showing us that the Laurence pure sand is coarser then Chenab sand and similarly Sargodha crush is … 4 SIEVE ANALYSIS INTRODUCTION: A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material. Lab report due: October 6th and 8th 2014. This test method is used to determine the grading of materials proposed for use as aggregates or being used as aggregates. hޤ�mo�0����W��#UH����:Um�2Hi����JݿߝC�*L�a�|�;ۏOpa#\D�K �%\hc"�%#�bˉe���ı����Q����¢C��8���ò(��:�g8����~��:�q�v�]d?3*W5('��ʅ�}�����>V�|��S�x=��콞��Sz7�M����|������d�N��Ξӷ�����l�^���f��jb

This gradation gives an indirect measure if the workability and average particle size. 2. International author ” Design of Reinforced Concrete” 9th edition Using the sieve shaker, sieve the air-dry or oven dry soil sample provided by the instructor. Fineness modulus is a single factor computed from the sieve analysis and is defined as the sum of the cumulative percentages retained on the sieve of the standard series divided by 100.
