aggregate as well as for the recycled aggregate. The use of recycled aggregate generally increases the drying shrinkage creep & porosity to water & decreases the compression strength of concrete compared to that of natural aggregate concrete. It is nearly

compressive strength of recycled aggregate concrete generally decrease with increasing recycled aggregate contents. For a recycled aggregate replacement percentage equals 100%, the elastic modulus is reduced by 45%. 2. Nelson, Shing Chai NGO in 2004[4] st

Recycled aggregate concrete have several reliable applications. However, countries like India need to take some serious urgent measures to unleash the scope of RAC and if done so, concrete recycling will become one of the most important element for constr

Crushed recycled concrete can also be used as the dry aggregate for brand new concrete if it is free of contaminants. Also, concrete pavements can be broken in place and used as a base layer for an asphalt pavement through a process called rubblization.

The addition of nano silica and ultrafine fly ash also improved the compressive strength of recycled aggregate concrete. Similar results are also observed in the case of indirect tensile strength. The carbon footprint of recycled aggregate concrete is sli

This paper discusses the mechanical properties and bond behaviour of recycled aggregate concrete (RAC). The recycled aggregates used were obtained from crushed concrete cubes of 2–3 years old. The properties of the aggregates were studied and a concrete o

The use of recycled concrete aggregate materials in highway constructions as compared to the use of virgin materials reduces virgin natural resource demands on the environment. In order to evaluate their potential use of recycle materials in highway const
