In April of this year, it became known about the creation of concrete, reinforced with the addition of graphene. Scientists at the University of Lancaster went even further, adding nanoplates obtained from plant fibers of common root vegetables to the traditional ingredients of concrete.
According to research director Professor Mohamed Saafi, cellulose-based wafers are mostly nanosheets synthesized from food waste - carrot roots and sugar beet.
When added to normal concrete, these structures increase the content of calcium silicate hydrate, the main component of Portland cement that is responsible for the strength of concrete.
According to the results of laboratory tests, the addition of nanoplates significantly increased the strength of concrete and reduced the consumption of Portland cement by 40 kg per cubic meter of concrete. In addition to the obvious economic effect of reducing CO 2 emissions, it has also been found that the addition of lamellas increases the microstructure density of the concrete, making it more durable and resistant to wear.
