You’d think that, even without signs or cones or big yellow flashing warning lights, you’d be able to tell if you were parking in wet concrete because, well, it’s wet. That wetness didn’t seem to stop a DeKalb County, Georgia, woman from doing so with her BMW, and she’s claiming there was no signage warning her the…
If you’ve driven anywhere in the United States, then you’re aware of how bad our roads are. Potholes, cracks and structurally deficient bridges all increase our travel times and cause extra wear on our vehicles. Part of the reason for this lies in the materials used in our infrastructure—but scientists have some new…
The next time you walk down a sidewalk and come to a street crossing, you may notice some strange bumps and patterns in the concrete. I always thought these were for water drainage or extra traction. I was wrong! The real reason is much more complex and fascinating.
Inside nearly everything made of concrete, you’ll find reinforced steel rods that compress the material, making buildings, bridges, and other structures even stronger. The rods aren’t designed to break easily, but when they do, the best way to watch the destructive results is through the lens of a slow motion camera.
Turns out, dropping a giant concrete block onto a car ends exactly like how you would imagine it would: the car gets completely obliterated and smashed to smithereens. Crash Zone pulled off this incredibly silly stunt and filmed it in slow motion so you can see the damage in lovely, exacting detail. The concrete block…
It’s not cheap, and it wasn’t easy to make, but scientist Dr. José Carlos Rubio has reportedly figured out how to make cement that glows in the dark. This could conceivably be the highway of our future.
Maybe “falling apart” is a bit of an overstatement, but “crumbling around the edges” is certainly accurate. This isn’t the first time the concrete track surface has been an issue, either. This time, it was the pit lane that started to crumble apart at the seam.
China and India might be buying weapons like Americans are buying discounted Nintendos, but this particular Chinese warship won't be threatening the Japanese islands anytime soon because, though it's a full-sized Nimitz-Class Aircraft carrier, it's made entirely of concrete.
The assumption some luxury buyers have is that if they're smart enough to earn the kind of money that keeps them in a premium car — like a Lexus GS — they're probably smarter than you, traffic cones, and a guy in a reflective vest yelling at them to stop.
No longer will the decision need to be made whether to have a driveway or a nice, beautiful lawn. A happy medium has been found in Grasscrete, a grass and concrete hybrid. It's essentially a checkered pattern of concrete that allows grass to grown between the blocks of concrete.
