Researchers at the University of Konstanz in Germany have shown that they can engineer stronger cement by giving the material a nano-level brick and mortar structure. Adding polymer binders into cement to control its nanostructure, the researchers developed a material 40–100 times more fracture resistant than standard concrete.
