2 meters wall of new UBC concrete withstood nearly triple the strongest quake ever recorded

The material is called an eco-friendly ductile cementitious composite (EDCC) and is so strong and flexible that it acts like steel, bending during an earthquake instead of crumbling like concrete.

Walls that are sprayed on both sides with the material performed so well in seismic tests that UBC engineers dubbed it the ‘unbreakable wall.’

Soleimani-Dashtaki had to turn the dial to three-times the magnitude of the strongest earthquake ever recorded in order to break down a two-meter wall of EDCC in seismic tests.

The technology developed at UBC will cut retrofit costs in half, added UBC civil engineering professor Nemy Banthia, who supervised the EDCC project.
