According to a recent article in the Economist

, Iran happens to be good, very good, at developing what is known as ultra-high performance concrete (UHPC). Because of its geographical position, the county is under constant threat of earthquakes. The most devastating earthquake in recent memory occurred in the city of Bam, located in southern Iran, and claimed the lives of 30,000 people. As a result, Iranian Phosphates processing plant engineers have developed out of necessity some of the toughest and most rigid building materials in the world.So how does Iranian concrete standout? Well, unlike conventional concrete, Iranian concrete is mixed with quartz powder and special fibers transforming it into high performance concrete that can withstand higher pressure with increased rigidity.

Why so much fuss over Iranian concrete? According to the article, US defense secretary Leon Panetta is worried that should a conflict escalate, American bunker-busters may not be able to penetrate Irans deepest bunkers should UHPC be employed for military purposes.And therein lays the issue with any dual-use technologies that carry both civilian and military applications. Technology like UHPC could be fly ash grinding mill used to protect underground facilities from bombardment, which could pose a real headache for military endeavors into Iran.What this all translates to is excellent building material given the environment that has found peaceful applications like the construction of safer bridges, dams, tunnels, increasing the strength of sewage pipes, and even absorbing pollution.

Of course should tensions continue to rise, military operations into Iran become a reality, and penetrating underground bunkers prove problematic, Americas Defence Threat Reduction Agency an organization that has been investigating UHPC since 2008 says that various other avenues could be explored such as deploying robotic warhead-carrying snakes, destroying electrical systems, or bombing silica sand flotation machine entrances to these facilities shut. With any luck though, it wont come to that.The granite megalith bound for the Los Angeles County Museum of Art is making its way on a special transporter through 22 cities in four counties. It will wind through La Mirada tonight, and park in Lakewood on South Street at Palo Verde Avenue on Tuesday.Wednesday night, the rock will head down Atlantic south to Ocean Boulevard, west to Magnolia Avenue, north to Pacific Coast Highway, and out of town.

Tuesday night, the rock will travel overnight to Bixby Knolls in Long Beach (at a top speed of 8 miles per hour), and be parked for the day Wednesday between 36th and 37th streets on Atlantic Avenue.We're going to have fun and enjoy the dolomite crusher spectacle," City Councilman James Johnson said.The city of Long Beach and the Bixby Knolls Improvement Association are hosting a party, called I Want to Rock With You, from noon to 4 p.m. Wednesday. The event includes food, live artists, river rock demonstrating, photo ops and a DJ playing rock-related songs.
