Jun 19, 2014#0183;#32;(a) Procedure For Fine Aggregate. Take minimum of 200 g of sample and dry it in an oven till it attains a constant mass. After drying the sample, cool it to room temperature and sieve it through a 300 micron sieve until all the material finer than 300 micron get separated. Weigh the material retained on the 300 micron sieve to the nearest g.
Calculate the percentage of coal and lignite as follows: Where: W 1 = Dry mass of Coal and Lignite in sample. W 2 = Dry mass of Plus No. 50 Materials (Fine Agg. Sample) W 3 = Dry mass of remaining portion of plus No. 4 material after coal and lignite have been removed (Coarse Agg. Sample). Fine Aggregate : % Coal and Lignite = W W x 100
The sampling and test methods shall be done with grading and fineness modulus test, organic impurities test, effect of organic impurities on strength test, soundness test, clay lumps and friable particles test, coal and lignite test, bulk density of slag test, abrasion of coarse aggregate test, reactive aggregate test, freezing and thawing test
