2021-6-22 More fineness modulus value indicates that the aggregate is a coarse sand small value of fineness modulus indicated that the aggregate is finer. Fineness modulus is a factor obtained by adding the cumulative percentages of aggregate retained on each of the sieves ranging from 80 mm to 150 mm micron and dividing this by 100.
2012-2-8 Calculation The aggregate impact value is expressed as the percentage of the fines formed in terms of the total weight of the sample. Let the original weight of the oven dry sample be WI g and the weight of fraction passing 2.36 mm I~ sieve be W 2 g. 8.
2020-7-4 The aggregate impact value is denoted by ‘AIV’ and it is determined using the IS 2386 part 4 test procedure. So, the above you have a typical image of the equipment. So, what you see is that basically you have a cylindrical steel cup at the bottom where the aggregates to be tested are taken and it is placed in a frame, impact test frame.
