...industry, is up to 10 times stronger than regular concrete. Although, pound-by-pound, it costs several times as much as regular concrete, industry officials say price comparisons are misleading because the high-tech versions have different properties that make them more comparable to materials such as stainless steel or aluminum - which are often more expensive still. The latest concretes have other advantages, including setting much faster. That's giving architects, engineers and builders far greater flexibility to use the material's long-lasting, thermal and acoustic properties in everything from pedestrian bridges to bus stations - and, in turn, contributing...
High-tech concrete is just one of the products that has emerged from the research and development labs of cement, steel and chemicals firms this decade, and it signals a growing commitment by heavy industry to the notion of "sustainability." As public pressure has grown to reduce energy use and carbon emissions - and in general tread more lightly on the environment - companies in these industries have poured money into R&D efforts. Much of the work has focused on internal processes, especially on the critical task of finding out how to cut down on emissions during manufacturing. But in their...
...team), which spans cities around the world over nine months, the building opened to the public in September during the first leg of the race, in Alicante, Spain; its next stop is Boston Harbor in April 2009. Designed by the architecture firm LOT-EK, the structure consists of 24 steel shipping containers, each weighing 11 tons, that stack on top of one another, creating a building that includes terraces, a Puma retail space and a lounge area.

Just as steel and auto workers fought against unsafe working conditions and unlivable wages, teachers too demanded protection from parents and administrators who would try to dictate lesson plans or exclude controversial materials like Huck Finn from reading lists. In 1887, nearly 10,000 teachers from across the country met in Chicago for the first-ever conference of the National Educator's Association, now one of the country's most powerful teachers' unions. The topic of "teacher's tenure" led the agenda. By the turn...
