Sieve Analysis of Fine and Coarse Aggregates: Apparatus and Procedure, Lecture notes of Materials science

The apparatus and procedure for conducting a sieve analysis of fine and coarse aggregates, as outlined in the canadian council of independent laboratories ls-602-r30 and c136-14 standards. The requirements for sieves, balances, mechanical shakers, and ovens, as well as the procedure for sieving and recording results.

What you will learn

  • What is the procedure for sieving and recording results in a sieve analysis of fine and coarse aggregates?
  • What are the requirements for the sieves used in a sieve analysis of fine and coarse aggregates?
  • What are the accuracy requirements for the balance used in a sieve analysis of fine and coarse aggregates?
