Jamia Milia Islamia, AMU invent eco-friendly cement using waste

10 Jun 2021 CW Team

The civil engineering faculty at Jamia Millia Islamia (JMI) in Delhi and Aligarh Muslim University (AMU) in Uttar Pradesh developed an environmental friendly version of cement in response to the alarming figures of cement production.

It can be used to replace 5-20% of cement in the construction process. Manufacturing of one tonne of cement can result in the release of up to 1,000 pounds of carbon dioxide. The ubiquitous material, which is used to build the majority of structures around the world, is also the world's third-largest carbon dioxide emitter.

While the world has produced 8 billion tonnes of plastic, more than twice that amount of cement is produced every two years, according to a 2018 report by Chatham House (a London-based non-profit organisation). Closer to home, India produced 329 million tonnes (mt) of cement in 2020, with projections of 381 mt in 2022.

While cement is the most common building material, it has a huge environmental impact. As a result, the world requires widespread adoption of less harmful and environmentally friendly cement alternatives.

Dr Ibadur Rahman, Mohammad Arif, Professor Abdul Baqi, Dr M Shariq, Er Mohammad Gamal Al-Hagri, and Er Amer Saleh Ali Hasan invented the green adhesive formula.

Four years ago, Dr Rahman began experimenting with and decoding nano-based modified cement and concrete composites.
