The Brick Industry Association (BIA) has announced its annual Brick in Architecture awards. The awards recognize outstanding works of nonresidential architecture completed since 2001 that employ clay brick as a prominent feature. Best in Class, Gold, Silver and Bronze awards were given in seven categories: commercial; educational/schools; health care facilities; municipal/government; house of worship; other institutional; and paving and landscape architecture. A national panel of five architects and three landscape architects judged the entries based on fulfillment of project goals, aesthetic interest and appeal and overall impression. In the Paving and Landscape Architecture category here are the winners:
Researchers at the University of New South Wales, Australia have developed bricks and building aggregate that can be manufactured entirely from waste fly ash. The result is a strong, lightweight building material that they believe could generate a thriving new ?EUR??,,????'?????<????????green?EUR??,,????'?????<???????? industry for countries such as China and India. Coal-burning power plants spend millions of dollars disposing of waste fly ash. An estimated 200 million tons of the byproduct is generated in China each year, much of it is sent to waste disposal sites on increasingly scarce land and it is also responsible for serious air and water pollution. In India about 100 million tons of fly ash is generated each year. The Indian government passed a law in October 2005 stating that a minimum of 25 percent of fly ash must be used in the manufacture of clay bricks. There are also restrictions on the excavation of topsoil for the manufacture of bricks. In the Middle East there is an acute shortage of durable building materials because of the lack of suitable clay, aggregate and sand. Karl Shaw, one of the scientists involved, says their unique manufacturing method traps any harmful chemicals, creating an eco-friendly construction material that saves on construction costs and reduces generation of greenhouse gases. They also generate fewer emissions during manufacture as the process uses less fuel than clay flash bricks, are 28 percent lighter and 24 percent stronger than comparable clay bricks.

According to the U.S. Geological Survey, they are at levels below human health concerns.
Italcementi, which spent 10 years developing its TX Active, said the building material is capable of reducing urban pollution by more than 40 percent, the Italian news agency ANSA reported in August. Tests on a road near Milan showed TX Active cut the level of nitrogen dioxide and carbon monoxide by as much as 65 percent. It functions via a chemical process called photocatalysis, whereby sunlight triggers a chemical reaction when titanium dioxide on the surface of the cement comes into contact with pollutants in the air. TX Active works most effectively in bright sunlight. Italcementi said test results have been verified by independent bodies like the National Research Council. TX Active cement has already been used on a number of buildings, including Air France?EUR??,,????'?????<????????????EUR??,,??s new headquarters at Paris?EUR??,,????'?????<????????????EUR??,,??
