Graphene, the wonder material discovered at the University of Manchester by Andre Geim and Konstantin Novoselov has been shown to strengthen cementitious materials including concrete at the molecular level. Graphene-reinforced concrete has greater compressive strength and water resistance (due to the low permeability of graphene). Scientists at Rice University recently demonstrated a process to convert waste from old rubber tyres into graphene which can, in turn, be used to strengthen concrete. Meanwhile, a joint venture between graphene specialists at the University of Manchester and alumni-led construction firm Nationwide Engineering has developed a product that could revolutionise the concrete industry and its impact on the environment. In a similar vein, researchers from the University of Tokyo have developed a new method of producing concrete without cement. Their technique offers a means for the construction industry to reduce its carbon emissions, as well as offering potential for building on the Moon and Mars. A five-year University of British Columbia study has concluded that recycled concrete can perform as well as – and in some cases better than – conventional concrete. Another alternative mix proposed by researchers for making concrete is to swap out the commonly used sand for a clay material that can easily be obtained as a waste from excavation works, resulting in a greener form of concrete.
