2 ASTM C 136 Standard Test Method for Sieve Analysis of Fine

2. ASTM C 136, \"Standard Test Method for Sieve Analysis of Fine and Coarse Aggregates\", requires that the nest of sieves used for sieve analysis be agitated an appropriate amount, such that, every individual sieve, having been weighed subsequent to every sh ing of the nest of sieves, would not have the mass o (1 Point) f its content vary by more than 1 % (in consecutive shakings) Because, over-sieving the sand would cause breaking off of the sand particles into smaller pieces Because, over-sieving the sand would indicate the sand to be finer Because, under-siev Because, under-sieving the sand would indicate the sand to be coarser All of the above are true mesh of the sieve ing the sand would not give ample opportunity for all particles to pass through the

Solution

Because, under -sieving the sand would not give ample oppurtunity for all the particles to pass through the mesh of the sieve
