Scientists strengthen concrete by 30 percent with used coffee grounds::Researchers in Australia have found a new use for old coffee grounds: concrete doping!.
Anyone else annoyed that they use kilos for coffee, but tons for concrete, and then give percentage by volume?
Gee, a controllable and fairly steady source of something that naturally generates methane. Better just bury it real quick because we’ve got fracking to do!
that must be some shitty coffee
From a materials science perspective, a jump of 30% for a material that’s been well known for thousands of years seems unlikely.
Well, not really. They only mentioned compressive strength, so other important qualities and measures could be worse in unacceptable ways.
Or maybe it’s great. https://www.concretecentre.com/Specification/Innovative-concrete/Charcoal-Concrete.aspx
Can we call it cofcrete?
