Do you have the right aggregate for your shotcrete mix ,, Screening test to separate the aggregate particles The process to obtain the grading curve consists in passing the aggregate sample through a series of standardized sieves of different diameters mounted on a column The aggregates are exposed to vibration and rotation movements in order to obtain the classification by sizeP&Q University Lesson 9, Sep 10, 2015· Gradation, however, is a characteristic that can be changed or improved with simple processes, and is the usual objective of aggregate-preparation plants Crushing, screening and blending are methods used to affect aggregate gradationsSIEVE ANALYSIS OF FINE AND COARSE AGGREGATE ,, sample size in order to determine the gradation of fine aggregate DOTD TR 113-11 Rev 12/11 Page 5 of 19 Method A Method of Test for SIEVE ANALYSIS OF FINE AND COARSE AGGREGATE DOTD Designation: TR 113-11 Method A I Scope This method of test is used to determine the particle size distribution of aggregates by dry ,Use of Manufactured Sand in Concrete and Construction An ,, BIS Guidelines IS: 383-1970 for selection and testing of Coarse and Fine aggregates available Generally, Sand is classified as Zone I, Zone II, Zone III and Zone IV (ie Coarser to Finer) There is sieve designation for each zone Gradation is made in accord with the usage of the sandExp 3 Sieve Analysis, 4- Larger value of FM is preferred for fine aggregat For a good fine aggregate, the FM should be between 23 and 31 (ASTM Range for fine aggregates) 5- A FM of 4 can be interpreted to means that the fourth sieve from bottom ie sieve No 16 is the average size of the aggregate particles in the given sample Sieve Analysis.
