Document Summary
Practical 2 constant head permeability test 5. This test is carried out to determine the percentages present of various sizes (governed by sieves used) of particles in soil (generally on soil particles coarser than 75 m) Set of sieves with different mesh opening sizes. Shaker to shake that stack of sieves. To perform this test, the following procedure was followed: Select a set of sieves and clean them. Measure the weight of each sieve and record. Obtain about 700 ~ 1000g of dry sand and pour it into the top sieve in the stack (note: measure and note exact mass of sand before putting it into the top sieve) Close the top sieve by using a lid and shake the stack of sieves for 3 ~ 5. Measure the mass of each sieve with retained sand and record the values. Remove the retained sand in each sieve and clean sieves min.
