ABSTRACT

 

The need for demolition, repairs and renewal of concrete and masonry structures is rising all over the world, more so in the developing countries. It is highly desirable that the waste materials of concrete and bricks are further reutilized after the demolition of old structures in an effective manner especially realizing that it will help in reducing the environmental damages caused by excessive reckless quarrying for earth materials and stones. Secondly, this will reduce pressure on finding new dumping ground for these wastes, thus further saving the natural environment and eco-systems. In this regard, the concerns expressed at Earth-92 conference held at Rio, Brazil, are very appropriate and thought provoking. Durability, reliability and adequate in service performance of these reused waste materials over the stipulated design life of designed structures are of paramount importance to Structural Designers. This paper critically examines such properties in reused concrete and brick masonry waste materials and suggests suitable recommendations for further enhancing life of such structures, thereby resulting in sufficient economy to the cost of buildings.

 

Keywords : Demolition, Environmental Damage, Reckless Quarrying, Earth Materials, Eco-System, Durability, Reliability, Reuse, Masonry Waste Material, Concrete Waste Material, Solid Waste, Dumping Grounds.
