Dr, Hongyan Ma, a researcher from the Missouri University of Science and Technology has been awarded a $160,000 grant from the National Science foundation to test a safer, simpler and more affordable method of combining nanoparticles with concrete to improve its strength and durability.
“Our method is to create calcium carbonate nanoparticles inside the concrete by blowing carbon dioxide into the highly diluted wet cement,” says Ma. “The nanoparticles will be formed inside this part of the suspension in the presence of siliceous ingredients, and you use that to mix the concrete.”
