Cement deal for WhitneyBy DAVID K. LI Last Updated: 10:22 AM, May 1, 2012 Here’s one way to cement Whitney Houston’s legacy: The pop diva’s family plans to encase her body in concrete — so that no one is tempted to rob the grave. The is $800,000 in jewels in Houston’s casket, and the singer’s family can’t afford 24-hour security to guard against ghoulish thieves, according to the newspaper The Daily Star. The British tabloid didn’t say when Houston’s family would dig up Whitney’s New Jersey grave and pour the cement.

Who is buried in the Hoover Dam? The Hoover Dam is one of the most phenomenal structures in modern history. This 1244 feet long, 660 feet thick, and 726 feet high concrete behemoth holds back so much water that it deformed the earth's crust and caused 600 small earthquakes in the decade after its construction. Over 100 workers died constructing the Hoover Dam — and legend has it, some of them are buried within its concrete facade. Is there anything to these rumors? An enormous number of deaths - Over 100 people died in the construction of the Hoover Dam....

Bunker-busting Smart concrete Iran makes some of the world’s toughest concrete. It can cope with earthquakes and, perhaps, bunker-busting bombs A DUAL-USE technology is one that has both civilian and military applications. Enriching uranium is a good example. A country may legitimately do so to fuel power stations. Or it may do so illegitimately to arm undeclared nuclear weapons. Few, however, would think of concrete as a dual-use technology. But it can be. And one country—as it happens, one that is very interested in enriching uranium—is also good at making what is known as “ultra-high performance concrete” (UHPC). Iran is...

A most unusual Roman structure depicting their technical advancement is the Pantheon, a brick faced building that has withstood the ravages of weathering in near perfect condition, sitting magnificently in the business district of Rome. Perhaps its longevity is told by its purpose . . . to honor all gods. Above all, this building humbles the modern engineer not only in its artistic splendor, but also because there are no steel rods to counter the high tensile forces such as we need to hold modern concrete together. Describing this large circular building tells much of the intelligence of its builders;...

ARCHAEOLOGISTS in Germany have found a 2,000-year-old glue Roman warriors used to repair helmets, shields and the other accessories of battle. "Caesar's superglue" - as it has been dubbed by workers at the Rhine State Museum in Bonn - was found on a helmet at a site near Xanthen on the Rhine River where Romans settled before Christ. Frank Welker, a restorer at the museum, said: "We found the parade cavalry helmet had been repaired with an adhesive that was still doing its job. "This is rightly called some kind of superglue because air, water and time have not diminished...

Sandy ash produced by a volcano that erupted 456,000 years ago might have helped a huge ancient Roman complex survive intact for nearly 2,000 years despite three earthquakes, according to research presented last week in Rome. X-ray analysis of a wall sample from the Trajan's Market ruins in Rome showed that the mortars used by ancient Romans contained stratlingite, a mineral known to strengthen modern cements. "It is the first time that stratlingite is recognized in ancient mortars," Lucrezia Ungaro, the Trajan Forum archaeological chief, told Discovery News. "This is amazing, and shows the technical expertise of Roman builders."

Daniel Deocampo, a Georgia State assistant professor of Geology, is investigating ancient lakes and volcanic ash to help scientists better understand the environment in which humans evolved, and eventually used ash and sediment to build infrastructure in ancient civilizations... His research into volcanic ash that formed sedimentary rocks in Italy and California helps scientists better understand the ways ancient societies, including the Romans, used rocks to create mortar and concrete that, in some cases, was actually more durable than the modern varieties. Over hundreds of years, Romans experimented with different volcanic ash layers to perfect the building materials which would...

Ancient Rome's Earliest Temple Reconstructed Sara Goudarzi for National Geographic NewsMarch 14, 2008 Experts have digitally reconstructed Rome's earliest major temple, the Temple of Apollo, built by the first Roman emperor, Augustus. The temple dates to 28 B.C., and its ruins stand adjacent to the emperor's imperial palaces on the city's famous Palatine Hill. Until now the original design of the temple had not been well understood, partly due to the ruins' poor state of preservation. Also, previous efforts to model the temple had been based on outdated historical assessments rather than on the ruins themselves. Stephan Zink, a graduate...

Research team recreates ancient underwater concrete technology A University of Colorado at Boulder professor and his colleagues have taken a page from the writings of an ancient Roman architect and built an underwater concrete pier in the manner of those set in the Mediterranean Sea 2,000 years ago. CU-Boulder history Professor Robert Hohlfelder, an internationally known underwater archaeologist, said scholars have long been in awe of the engineering feats of the early Romans. A former co-director of the international Caesarea Ancient Harbor Excavation Project, he said the research effort was spurred by the stunning hydraulic concrete efforts undertaken at...

One of the strangest, and most useful, bombs employed in Iraq has been the concrete filled smart bomb (laser guided or JDAM). Why deliver a 500 pound bomb filled with concrete instead of explosives? You do that if you want to do some damage, but not a lot. Concrete JDAMs were first used in the 1990s to destroy anti-aircraft guns, radars and missiles that Saddam Hussein placed in residential areas. He believed that the Americans would not attack these weapons, for fear of hurting nearby civilians. But it turned out that a laser, or satellite (JDAM) guided concrete smart bomb...

White House hints that time for new Gaza policy is near. WASHINGTON — The Obama administration said Wednesday that it had warned Israel's government repeatedly to use "caution and restraint" with half a dozen aid boats bound for the Gaza Strip before Israeli commandos raided the flotilla this week in an operation that killed nine people. In an interview with Charlie Rose broadcast Wednesday night, Vice President Joe Biden agreed that Israel had a right to inspect the cargo. "You can argue whether Israel should have dropped people onto that ship or not ... but the truth of the matter...

This 640-pound concrete elk statue lies on its side in the backyard of Mark and Carol Brye’s home in rural Viroqua. The dead buck lies about 20 feet away. A love-struck buck ran out of luck a week ago. The seven-point buck was killed when it rammed a 640-pound concrete statue of an elk in the backyard of Mark and Carol Brye's home in rural Viroqua. Bucks often fight during the breeding season, commonly called the rut. Dominant bucks defend breeding territories and female deer by sparring with subordinate bucks. Antler battles sometimes result in the death of one or...

BOSTON (AP) — Two former managers of a Big Dig contractor pleaded guilty Wednesday to being part of a conspiracy to deliver substandard concrete to the massive highway project. Six former managers of Aggregate Industries NE Inc. were indicted in 2006 on charges they falsified records to hide the inferior quality of more than 5,000 truckloads of concrete. They were accused of recycling concrete that was too old or already rejected by inspectors and in some cases double-billing for the loads.

Soaring above the Mississippi River just east of downtown Minneapolis is one remarkable concrete job. There on Interstate 35W, the St. Anthony Falls Bridge carries 10 lanes of traffic on box girders borne by massive arching piers, which are supported, in turn, by footings and deep pilings. The bridge, built to replace one that collapsed in 2007, killing 13 people, is constructed almost entirely of concrete embedded with steel reinforcing bars, or rebar. But it is hardly a monolithic structure: the components are made from different concrete mixes, the recipes tweaked, as a chef would, for specific strength and durability...

OCEANSIDE — Robertson's Ready Mix has decided not to build a long-disputed concrete batch plant in the Oceanside Boulevard corridor. Friends of Loma Alta Creek announced a settlement yesterday in its nearly year-old suit to force the company to prepare a full environmental impact report for the project. Nadine Scott, spokeswoman for the group, said the company has agreed not to build its proposed plant at 2847 Industry St. “We were really surprised” at Robertson's decision, Scott said yesterday. The city has agreed that any new project proposed for the site cannot use Robertson's permit, but would have to go...

Egypt's Pyramids Packed With Seashells Jennifer Viegas, Discovery News Fossil-Filled April 25, 2008 -- Many of Egypt's most famous monuments, such as the Sphinx and Cheops, contain hundreds of thousands of marine fossils, most of which are fully intact and preserved in the walls of the structures, according to a new study. The study's authors suggest that the stones that make up the examined monuments at Giza plateau, Fayum and Abydos must have been carved out of natural stone since they reveal what chunks of the sea floor must have looked like over 4,000 years ago, when the buildings were...

Scientists say pyramids could be concrete April 23, 2008 Scientists are taking a new look at Egypt's pyramids to see if some of the blocks could have been made from concrete. Linn W. Hobbs, a materials science professor at Massachusetts Institute of Technology, told The Boston Globe there is a chance ancient Egyptians could have cast the blocks from synthetic material instead of carving them from quarries. Scientists have long believed Romans were the first to use structural concrete. Undergraduates in MIT's Materials in Human Experience class are building a scale-model pyramid made of quarried limestone and blocks cast from...

Innovations in methods and ingredients have made possible lightweight bridges, color-changing buildings, and furniture created from this efficient material Concrete is ubiquitous in the modern world, yet most people don't give it a passing thought. Why would they? It may be the most consumed substance on earth after water, but the stuff of pavements and parking garages is also a bit dull—or so most of us thought. In fact, innovations in the science of concrete have enabled architects and designers to achieve remarkable feats that would have been impossible in earlier years—everything from ultra-thin bridges spanning hundreds of feet to...

Drexel University researchers are revising the book on the Pyramids of Egypt, the last surviving wonder of the ancient world. The standard hypothesis for their construction speculates that ancient Egyptians carved the blocks out of nearby deposits of natural limestone, using stone age tools, and then floated the stones on barges, and used primitive ramps and levers to wrestle the blocks into place. The fact is, no one knows even to this day how the Pyramids were built. Many of the limestone blocks fit so perfectly that not even a human hair ....

Where can you go to see a cool example of nanotechnology? Well, just about everywhere. A new study reveals that plain old concrete, the most common human-made material on the planet, owes its properties to its nanoscale structure. Down the road, this new understanding could lead to novel forms of concrete that require less energy and CO2 to generate and might allow researchers to engineer its properties much as they have done with advanced steel alloys. Concrete isn't what comes to mind when most people think of nanomaterials. It's the oldest engineered construction material and was first used by the...

From recycling electronics to shredding sensitive documents, now recycling old tires can become easily maintained sidewalks. Sixty-five cities are reducing the number of old tires dumped in landfills. Companies shred them, bake the fine particles and the use the material for sidewalks. These interlocking panels have cracks between them to allow water and air to reach tree roots, which delays the upward thrust of the roots. When the roots do rise, the panels will not break, making repair easier. The cost of the rubber sidewalks is three times more than concrete, but in the long run it is less expensive...

The red-hot real estate market shows no sign of cooling, but there could be a cloud on the horizon. The shortage of a humble but irreplaceable material could slow the growth of new housing. In parts of the Pacific Northwest, for instance, there's not nearly enough cement, 15% less than last year even as demand has climbed by 30%. "It's definitely affected our bottom line," says Dave Bertsch, president of Champion Concrete Pumping. "If it continues, we're going to have some layoffs. We are going to have to liquidate some equipment. It's a domino effect."

U-M researchers make bendable concrete click image to see video ANN ARBOR, Mich.—A new type of fiber-reinforced bendable concrete will be used for the first time in Michigan this summer—and University of Michigan scientists hope that their new material will find widespread use across the country. The new concrete looks like regular concrete, but is 500 times more resistant to cracking and 40 percent lighter in weight. Tiny fibers that comprise about 2 percent of the mixture's volume partly account for its performance. Also, the materials in the concrete itself are designed for maximum flexibility. Because of its long...

The experimental lightweight concrete on the new Benicia Bridge is not drying properly, and Caltrans says it may need $130 million to correct the problem. It is only the latest in a series of snafus that have plagued the new Interstate 680 span and caused costs to shoot up from an official estimate of $385 million in 1999 to $1.06 billion before Caltrans' discovery this week. First, poor rock quality under the Carquinez Strait slowed and complicated the construction of foundations. Then, noise from the work unexpectedly killed endangered fish. Then, Caltrans design mistakes, including failing to prepare for construction...

New, Smaller Planes Crowding Skies Once Left to Big Jets By MATTHEW L. WALD WASHINGTON, March 6 — For years the skies have been crowded with airplanes, but the planes' capabilities have kept them at different altitudes, with small, piston-driven models a few thousand feet above ground, commuter turboprops in the 20,000-foot range and jet airliners at 30,000 feet or higher. Now, to the dismay of aviation experts, an increasing number of planes may begin competing for space at the same higher altitudes. The turboprops are disappearing and being replaced by "regional jets," which fly at big-jet altitudes. Some...
