Studies on Concrete Made of Recycled Materials for Sustainability

Present research is an effort to study the properties of concrete incorporating industrial wastes such as demolished concrete, SF and FA. Recycled coarse aggregate (RCA) concrete construction technique can be called as ‘green concrete’, as it minimizes the environmental hazard of the concrete waste disposal.

Studies on Concrete Made of Recycled Materials for Sustainability

Construction industry uses Portland cement which is known to be a heavy contributor to the CO2 emissions and environmental damage. Incorporation of industrial wastes like demolished old concrete, silica fume (SF) and fly ash (FA) as supplementary cementing materials (SCMs) could result in a substantial reduction of the overall CO2 footprint of the final concrete product.

MIT students fortify concrete by adding recycled plastic

Oct 25, 2017  Concrete is, after water, the second most widely used material on the planet. The manufacturing of concrete generates about 4.5 percent of the world’s human-induced carbon dioxide emissions. Replacing even a small portion of concrete with irradiated plastic could thus help reduce the cement industry’s global carbon footprint.
