Aggregates: Physical Properties and Mechanical Properties

Physical Properties of Aggregate: Elongation Index The elongation index on an aggregate is the percentage by weight of particles whose greatest dimension (length) is greater than 1.8 times their mean dimension. The elongation index is not applicable to sizes smaller than 6.3 mm. The elongation index is the total weight of the material

3 Physical and Chemical Properties of Aggregate

The physical properties of aggregates stem from the inherent properties of the source rock; these include texture, structure, and mineral composition. Textural properties give rise to internal characteristics, of which the pore size is perhaps most important. Structural characteristics define the degree to which the minerals within the aggregate are segregated or oriented in one
