In India 25 – 30 million tonnes of C&D waste are generated, whereas only 5% of it is recycled. Hence, the life cycle assessment (LCA) of the production of recycled coarse aggregate (RCA) is conducted and compared with that of natural coarse aggregate (NCA) in accordance to the Indian scenario. In this context, the primary data during the

Since China hosted the Olympic Games in 2008, a mass of construction and demolition (C&D) wastes were produced with the rapid urbanization construction. Recycling the C&D waste into recycled aggregates (RA) is an effective method for reducing the amount of C&D wastes. Many studies on the properties of RA and the durability of recycled aggregate concrete (RAC) were conducted in China …
mixes were made. In each mix natural coarse aggregate was replaced by recycled coarse aggregate in the ratio of 0%, 20 %, 40%, 60%, 80% and by volume. The preliminary mix design was carried out using Nan-Su method for target strength of 40 MPa. After the initial mix design, the trial mixes were prepared and tested for the
