Special concrete aerosols help prevent earthquakes

Canadian scientists create a new type of concrete that is resistant to earthquakes due to the strength and toughness of steel.

Scientists at the University of British Columbia (UBC) in Canada, developed an environmentally friendly, aerated concrete , making the walls of buildings as steep as steel and resistant to the battles. a large earthquake, according to Inhabitat. This material is called Flexible Composite Cement (EDCC) with a major component of fly ash , an industrial byproduct.

"The cement industry generates nearly 7% of global greenhouse gas emissions." By replacing 70% of cement with fly ash, we can reduce the amount of cement used, which is an urgent need. because the production process one ton of cement freeing nearly a ton of carbon dioxide _(CO2) into the atmosphere ", Nemy Banthia, a professor at UBC, said.

EDCC products have very similar characteristics to steel. It is durable, flexible and flexible than regular concrete. For testing, the team sprayed concrete walls with an EDCC layer of about 10mm thick. They then simulated a magnitude 9 earthquake, the equivalent of the tremors of the Tohoku earthquake that struck Japan in 2011.

Test results are very surprising. The EDCC wall stands firmly in front of strong shakes, while the uncoated wall of EDCC collapsed about 65%. " An 10 mm layer of EDCC is enough to reinforce the inner wall against seismic effects," said Salman Soleimani-Dashtaki, a member of the team.

EDCC is now available in the market in British Columbia, Canada. The first project to use this product is an elementary school in Vancouver, Canada, in the fall of 2017. The team believes that the EDCC technology will help build buildings in the face of strong earthquakes, Significantly reduce the damage to humans.
