Cement Is Stronger When Its Molecules Are Busted
Geege Schuman stashed this in Ecology
Better living through chemistry!
The cement industry in the US contributes about 3.5 percent of the country’s emissions. Worldwide, the industry contributes to about 5 percent of all emissions.
So, even though concrete mixing facilities don’t blight the landscape like smoking oil refineries or jammed freeways, they are ripe for sustainable innovations. Like this one: Use less concrete by making it stronger. Ironically, this strength could come by making cement—the chemically-reactive powder that forms a brittle paste when exposed to water—with more molecular defects.
I didn't realize that less concrete makes it stronger. Seems like a win-win.
