Strength and Durability Performance of Fibre Reinforced Pavement Quality Concrete with Copper Slag as Fine Aggregate

This research focuses on the use of copper slag as fine aggregate incorporated with steel fibre at a dosage of 0.4% to 1.6% with an increment of 0.4%. The mechanical properties, such as compressive strength, flexural strength and fatigue life, were investigated. The durability parameters such as acid, alkaline, sulphate, chloride resistance and resistance to abrasion and skid were investigated. The results obtained reveal that the concrete with copper slag and steel fibre possesses better mechanical properties, and concrete having copper slag as fine aggregate possesses high durability characteristics. The flexural strength has increased 2 times. A strong relationship between flexural strength and fatigue life was noted.
