Correct Answer: B
Explanation:
Researchers plan to retrofit a school building in quake-prone Uttarakhand with a novel concrete coating that can dramatically enhance the earthquake resistance of seismically vulnerable structures.
The fibre-reinforced concrete was developed at the University of British Columbia (UBC) in Canada.
The material is engineered at the molecular scale to be strong, malleable, and ductile.
Researchers subjected the material, called eco-friendly ductile cementitious composite (EDCC), to earthquake simulation tests.
The material will be used to retrofit a school in Roorkee in Uttarakhand, a highly seismic area, researchers said.
EDCC combines cement with polymer-based fibres, fly ash and other industrial additives.
