Soundness of Aggregates

Soundness of aggregates is the ability of aggregates to resist change of volume due to change of physical condition. These physical conditions include freezing and thawing,temperature change, alternative change of drying and wetting in normal condition and alternative change of drying and wetting in salt water.The aggregates which are weak, porous and containing undesirable materials undergo large volume change in change of those physical conditions.
