Abstract

The increased use of concrete in construction industry has resulted in excessive consumption of natural aggregates. In recent years, the use of recycled concrete aggregates, obtained from construction and demolition (C&D) waste, in the development of new eco-friendly concretes has received significant attention. This technology has the promising potential of conserving natural resources while also reducing the negative environmental impact of concrete industry. However, the production of recycled aggregate concrete (RAC) with comparable properties to the conventional natural aggregate concrete (NAC) remains a major challenge for researchers. This chapter presents the current state of research on the long-term behavior of concretes manufactured with coarse recycled concrete aggregates, discussing their long-term compressive, flexural, and splitting tensile strength, elastic modulus, water absorption, air/water permeability, chloride permeability, carbonation resistance, frost resistance, as well as their creep, shrinkage, and fatigue properties based on the results of studies reported in the literature.
