DeClements uses vertical rebar with horizontal steel ties, plus a layer of waterproof insulation, electrical wiring and plumbing.
These small, electric-powered mills can be turned on and off quickly and cheaply turn scrap into angles and rebar.
Moreover, the facility is expected to generate less than three tenths of one percent of total U.S. rebar production.

And the water is a potentially lethal stew of fuel, broken glass, jagged car parts, and concrete and rebar from the fallen bridge.
If the Chinese get their hands on advanced rebar technology, this would enable them to build concrete platforms robust enough to reach low earth orbit.

That's all good news for Commercial Metals (54, CMC) , which operates small steel mills, mostly in the South, that make the rebar needed in concrete.
Every steel beam, every piece of rebar, and every bolt was handled with respect as the construction workers knew full well what they were a part of.
To summarize what he was talking about, he used the example of steel minimills coming about, but at their inception were so crappy they could only make rebar.
In addition, rebar casing was punched 165 feet into the bedrock and encased in concrete, and 18 caissons and 54 piles were also utilized to provide stability to the building.
In the meantime the rebar market became a commodity and the prices collapsed, forcing the minimills to improve themselves to move up to the next best thing to make for steel.
Eventually the established steel mills ceded the rebar market to the minimills which gave them a boost to their stock and revenue, and so it felt good to get out of that market.
The failure test described above involves so much force that a special footing needed to be constructed, involving 90 tons of rebar, and 1650 cubic yards of concrete (involving continuous pour from 165 trucks).
Schools lay in heaps of concrete and rebar, and the Central Propaganda Department, a government agency with the power to remove editors and shut down publications, banned coverage of rescue efforts at the schools.
Nearby, across a broad wooden deck that surrounds the cooling water ramp, stands a British Mandate-era lighthouse, erected in 1936, its cement chipped away by the salt air to reveal a crosshatch of bare rebar.
You're very, very cautious when you're feeling around because there could be objects there, and of course in the particular case of up north now they have twisted metal, jagged pieces of metal and rebar, which is metal enforcing bars that go into concrete roads, for instance.
Fact: The manufacture of reinforcing steel bar also known as rebar is based on technology first developed by the Defense Advanced Research Projects Agency during the Cold War and commercialized by a joint venture between Dean Kamen and Stephen Hawking (the JV holds the patents, valued at over USD 75 billion).
