The Stabilization of Weathered Dolerite Aggregates with,

Dolerite is a medium grained igneous rock with composition similar to basalt and is usually found in dykes or sills. The physical and chemical properties of dolerite make it a versatile material, which can be used as a crushed aggregate in producing concrete and as a road subbase .Comparative Evaluation of Dolerite and Syenite as Crushed,,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.(PDF) The Stabilization of Weathered Dolerite Aggregates,,The Stabilization of Weathered Dolerite Aggregates with Cement, Lime, and Lime Fly Ash for Pavement Construction February 2014 Advances in Materials Science and Engineering 2014(1):1-11
