Bendable Concrete: What is that?

Scientists have recently created bendable concrete which is one step closer to hitting the market. The brand new concrete is composed of coal plant waste and synthetic fibres. The concrete itself is devoid of cement. With added features, it also helps reduce the environmental footprint. Bendable concrete is a mix of small fibres, generally polymer-derived, compiled into a microstructure. It helps give the material increased ductility in comparison to traditional concrete. Traditional concrete just cannot bend without breaking.

The researchers out of Swinburne University in Melbourne, Australia developed this new type of concrete. As mentioned before, this one is bendable and doesn’t require cement to compose it. In a test, the team put a gigantic weight on top of two pillars of concrete. The first traditional slab of concrete snapped under considerable pressure but the second one is where the wonder lies.

The second slab made use of synthetic fibres in the concrete mix. To manufacture it, they came up with a procedure which does not require heat to cure it. This radically reduces the impact on the environment. The heating of limestone is not required to make the cement component. It also emits a huge 76% less carbon dioxide which is definitely a better thing for the world. Behzad Nematollahi, a researcher involved in developing the material added that it is 400 times more bendable than regular concrete. It is ideal for environments around Earth that are prone to earthquakes.

Also known as Engineered Cementitious Composites (ECC), bendable concrete isn’t something new. Dr Victor Li, a civil and environmental engineering professor at the University of Michigan made it in the early 1990s. However, cost, supply chain concerns, and technical factors have prevented its widespread adaptation in the construction industry. As of 2019, it was 4 times more expensive to make than good old traditional concrete. Here’s hoping that this new bendable concrete can be produced cheaply on a mass scale.

Tamil Nadu is set to host one of India’s five national carbon capture and utilisation (CCU) testbeds, aimed at reducing CO2 emissions in the cement industry as part of the country’s 2070 net-zero goal, as per a news report. The facility will be based at UltraTech Cement’s Reddipalayam plant in Ariyalur, supported by IIT Madras and BITS Pilani. Backed by the Department of Science and Technology (DST), the project will pilot an oxygen-enriched kiln capable of capturing up to two tonnes of CO2 per day for conversion into concrete products. Additional testbeds are planned in Rajasthan, Odisha, and Andhra Pradesh, involving companies like JK Cement and Dalmia Cement. Union Minister Jitendra Singh confirmed that funding approvals are underway, with full implementation expected in 2025.

As per a news report, Karan Adani, ACC Chair, has said that he expects the cement industry to benefit from the an anticipated US$2.2tn in new public infrastructure spending between 2025 and 2030. In a statement he said that ACC has crossed the 100Mt/yr cement capacity milestone in April 2025, propelling the company to get closer to its ambitious 140Mt/yr target by the 2028 financial year. The company’s capacity corresponds to 15 per cent of an all-India installed capacity of 686Mt/yr.
