Roads That Repair Themselves?!
I hope someone at the Michigan Dept. of Transportation is looking into things like this to repair all the roads in Michigan from all those winter potholes. I’d love to buy stock in the company that makes this stuff if it actually works and is an economically viable product.
Flexible Concrete That Can Repair Itself
“Researchers at the University of Michigan have created a concrete material that can heal itself when it cracks, paving the way for safer roads and bridges that are less likely to crumble from earthquakes and overuse. The self-healing concrete works because it can bend. When it’s strained, man microcracks form instead of one large crack that causes it to fail. A handful of drizzly days would be enough to mend a damaged bridge made of the new substance. The dry material exposed by the cracks reacts with rainwater and carbon dioxice in the air to form “scars” of calcium carbonate, a strong compound found naturally in seashells. The new material looks like regular concrete, but is 500 times more resistant to cracking and 40% lighter in weight. The concrete is studded with specially-coated reinforcing fibers that hold it together. Nanoparticles that comprise about 2% of the mixture’s volume partly account for its performance.”

Church Of The Holy Trout
The morning was perfect: the temperature was neither too hot or too cold, no bugs, sunshine coming up for a change, blue skies, and the tolling of the wilderness bell to come to Church. I answered the call and the message this morning was one filled with wonder. The choir was rapturous and the brethren enjoyed a communion of nature.
