Researchers from University of British Columbia (UBC) in Canada have developed earthquake-proof fibre-reinforced concrete that can dramatically enhance the earthquake resistance of seismically vulnerable structures.
The cement material is engineered at molecular scale to be strong, malleable, and ductile similar to steel. It is capable of dramatically enhancing earthquake resistance of seismically vulnerable structure when applied as a thin coating on surfaces.
The material is made of eco-friendly ductile cementitious composite (EDCC) which combines cement with polymer-based fibres, flyash and other industrial additives, making it highly sustainable. It was subjected earthquake intensities as high as magnitude 9.09.1 earthquake during simulations. In India, EDCC will be retrofitted in school at Roorkee in Uttarakhand, a highly seismic area for research purpose.
