Effects of Particle Size Distribution on Compaction Behavior and Particle Crushing of a Mudstone Particle Mixture

Abstract

Based on a standard compaction test and a standard sieve analysis test on five tested materials, the effects of the particle size distribution on the compaction behavior and particle crushing of a crushed mudstone particle mixture were investigated. Testing results indicate that the value of the maximum dry density ranges from 2.09 to 2.17 g/cm3, the optimum moisture content from 7.40 to 11.66 %, and the average relative breakage from 0.065 to 0.285, respectively. Based on the tested data, the variations of the maximum dry density, optimum moisture content and average relative breakage, with the median particle diameter and gravel content of the tested mixtures, were analyzed, respectively.
