WebElongation index of an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than one and four-fifth times (1.8 times or 9/5 times) their mean dimension. It is measured on particles … WebThe particle shape of aggregates is determined by the percentages of flaky and elongated particles contained in it. In. the case of gravel it is determined by its angularity number. For base course and construction of bituminous and. cement concrete types, the presence of flaky and elongated particles are considered undesirable as they may cause. birthmark story summary
