Ancient Brick Methods Rescuing Egyptian Monument






The nearly 5,000 year-old Shunet el-Zebib mud-brick monument is being buttressed with new brick?EUR??,,????'??+just like they were made BCE.


The nearly 5,000 year old Shunet el-Zebib mud-brick cultic monument, the only surviving example, was built at Abydos as a setting for King Khasekhemwy?EUR??,,????'???s mortuary cult rituals at the end of Egypt?EUR??,,????'???s Second Dynasty, circa 2750 BC. While the survival of the ancient mud brick is incredible, time had taken its toll and it was in danger of collapsing. Beginning in 2001, a conservation and stabilization program was developed, sponsored by New York University?EUR??,,????'???s Institute of Fine Arts. The plan does not involve modern construction techniques, but using the same mud brick of the ancients. The project director for the program is Dr. David O?EUR??,,????'???Connor, the Lila Acheson Wallace Professor of Egyptian Art and Archaeology, Institute of Fine Arts at New York University. The monument, which occupies more than two acres, is not being restored to its original appearance, but preserved in a way that reflects its antiquity. The weakest points are being repaired, but many of the visual scars inflicted by time will remain. The conservation of the monument is about half completed.

Shunet el-Zebib comprises two concentric enclosure walls, the inner still mostly standing to near its original height of 35 feet and defining a large open ritual space embellished by a substantial mud brick chapel.

LSU Retrofits for Disabled






Handicap-accessible crosswalks are being installed at LSU.

Louisiana State University, home to our ordinance associate editor, Buck Abbey, ASLA, professor of landscape architecture, has an ongoing effort to improve handicap accessibility on campus as established by the 1990 Americans with Disabilities Act.

?EUR??,,????'??Unless you?EUR??,,????'???re in a wheelchair, it?EUR??,,????'???s really hard to know there?EUR??,,????'???s a problem,?EUR??,,????'?? Dennis Mitchell, the campus landscape architect, told a student paper reporter.

Construction began during the winter break, with about 40 ramps and curbs ripped up. Among the features will be putting brick with a bumpy surface at curb approaches as a tactile warning for the visually impaired. (We know of one ?EUR??,,????'??bumpy?EUR??,,????'?? system developed by Tilco Vanguard, what it calls ?EUR??,,????'??Braille for your feet,?EUR??,,????'?? or what the industry calls ?EUR??,,????'??truncated domes.?EUR??,,????'?? The Snohomish, Wash. paving company employs a strip of raised yellow buttons with a bit of bounce in them, each about the size of a silver dollar.)

The projected cost for the new curbing and ramps is $512,000.

Benjamin Cornwell, associate director of disability services, indicated part of the funded is financed by a once a year $3.50 student fee.

The university matched the student fee totals and the state matched the total funds.






Masonry Institute of Iowa Awards Fountain Design






Intricate steer head terra cottas (below) from the razed Live Stock National Bank & Exchange Building are now spouts for the new fountain (above).







Landscape architects know the value of artistic touches to a project. Take the Masonry Institute of Iowa?EUR??,,????'???s 2006 Grand Award winner?EUR??,,????'??+the Roth Fountain in Sioux City, Iowa. The new fountain has an interesting history. The Live Stock National Bank & Exchange Building in Sioux City, Iowa was designed by architect William Steele in 1915, which included intricate terra cotta designs of steer heads, florals, geometic shapes and signage by Scotsman G.G. Elmslie.

Some of that terra cotta is now in the Sioux City Public Museum, saved after the building was mostly destroyed by fire in the winter of 1998. Fountain designers, Steve Blenderman, an artist, and Kirk Hoefling, a sculptor, had the idea of designing a fountain as an homage to the old building. They replicated the building?EUR??,,????'???s bricks, finding a manufacturer in Tennessee, and used some of the building?EUR??,,????'???s terra cotta, including four steer heads, as water spouts. They designed 16 foam jets that shoot water into the air around the central 16.5-foot tower.

Environmentally-Friendly Cement Claimed by Spanish Scientists

Spanish scientists from the Consejo Superior de Investigaciones Cient??ficas (CSIC) have developed a new type of cement they believe could greatly reduce carbon dioxide emissions from the cement industry and reduce energy consumption in the production of cement by up to 50 percent. The reason is cement is normally produced at 1,450 degrees centigrade (2,642 degrees Fahrenheit).

The new cement can be produced at between 60 to 80 degrees centigrade (140-176 degrees Fahrenheit). Eggs, for instance, are typically cooked at about 160 degrees Fahrenheit.

???-ngel Palomo, the scientist leading the research team for CSIC, presented his findings to the European Consortium for Research into New Materials the first week of Feb. 2007.

Palomo explained another important advantage of the new cement is it uses ash from burnt coal, an abundant industrial by-product worldwide. The new cement has been submitted to various tests.

Palomo asserts the results show the new cement is equivalent to the cement currently produced, and better in some ways.
