Recycled aggregates in concrete: a performance-related approach

Leading on from the foundation research and development projects undertaken and published in several papers by the authors on the use of recycled and manufactured aggregates during the past 15 years, this paper describes the experimental work carried out to compare the strength, load-dependent and load-independent deformation characteristics of concrete made from 30 normal-weight, natural, recycled and manufactured aggregates. The main aim of this specific study was to explore the possibility for considering all normal-weight aggregates within the framework of BS EN 12620 under one umbrella and thereby removing the stigma commonly associated with the recycled and manufactured materials. This 3-year extensive research led to the development of a performance-related approach that rationalises the use of recycled aggregate in concrete and could lead to its greater use and contribution to the global sustainability agenda.
