Utilization of Marble Dust in Pavement Quality Concrete

Concrete is highly versatile construction material in nature. Concrete's constituent materials are available naturally in all parts of the world. With more construction projects everywhere and due to the great utility of concrete in constructions, with each passing day these materials are getting deficient thus asking for the alternatives. Utilization of waste material in pavement quality concrete can be beneficial in order to find an alternative solution to reduce environmental pollution. The marble stone is most widely used in the construction and it generates marble dust through cutting and polishing of the stone. Marble dust is a waste material consisting of very fine powder and thus creating environmental problems worldwide today. Disposal of this marble waste leads to health hazards like respiratory and allergy problems to the people around. It also causes the pollution of air, water and soil. In this work, systematic experimental study has been carried out using marble dust to replace sand at various replacement levels in pavement quality concrete. This study has been carried out for w/c 0.40 and 0.42 and specimens have been cast to perform various tests (Compressive Strength Test and Flexural Strength Test), durability properties (Water permeability test, Abrasion resistance test), ultrasonic pulse velocity meter test and impact test.
