THE GLOBAL CHALLENGE OF RECYCLED CONCRETE

Most of the Construction and Demolition (C&D) waste is concrete and masonry rubble, which could be recycled and reused in the construction industry. At present, very limited quantities of concrete rubble waste are recycled. Experiences and results presented in this paper show very favourable recycling possibilities in this field. From a solely economical point of view, recycling of rubble waste is only attractive when the recycled product is competitive with natural resources in relation to their cost and quality. In addition, recycled materials will be competitive where there is a shortage of both raw materials and suitable disposal sites. This paper presents options and barriers for implementation of integrated recycling of concrete and C&D waste management. For the covering abstract see ITRD E112391.
