Sprayable earthquake-resistant concrete could ‘save lives,’ researchers say
Researchers at the University of British Columbia have developed a spray-on concrete substance they say will make buildings earthquake-resistant and can be used to retrofit schools for half the price.
“This material can be sprayed on vulnerable structures to significantly enhance their resistance to earthquakes and save lives,” said Nemy Banthia, a UBC civil engineering professor.
In the coming weeks, the material will be used to strengthen Dr. Annie B. Jamieson Elementary School in Vancouver, which is already undergoing upgrades.
Researchers hope the material will be used to strengthen other schools and buildings around the province.
“If you look at our B.C. schools, you will see miles and miles of unreinforced masonry corridor walls, and, during an earthquake, these are the corridor walls that would collapse and our children would suffer causalities, unfortunately,” said Banthia.
