Dolerite and syenite were comparatively studied and evaluated for their potential as crushed stone for civil engineering construction. Properties of the rocks tested included specific gravity, moisture absorption, Schmidt hammer rebound, point-load strength, unconfined compressive strength, Los Angeles abrasion, aggregate crushing value, sodium sulphate soundness, and ultrasound velocity.
