The material, best known as AAC, has been heralded as the building material of the new millennium. It's a lightweight, easily-crafted manufactured stone, strong enough to withstand earthquakes and hurricanes when reinforced with steel.
The material is used widely worldwide, says Mahgoub, who will be a featured speaker early next week at the 2012 China-US BOAO Manufactured Stone Conference in Zhengzhou Henan, China.
Mahgoub is also the coordinator of the NJIT Concrete Industry Management (CIM) program, which is only one of a select few programs of its kind across the U.S. This semester CIM students are testing and analyzing AAC. "It is an environmentally-friendly solution for future building problems and it is also an extremely efficient, specialty fabrication material," he says. "Cuts can easily be factory controlled. AAC is available throughout the U.S. and Canada. There is currently one U.S. manufacturer in Florida with plans to open another manufacturing operation in New Jersey."
ATTENTION MEDIA: To examine AAC samples and learn more about the material, Dr. Mahgoub will be available for interviews at NJIT on Nov. 19-20, 2012. Please contact Sheryl Weinstein, Sheryl.email@example.com, 973-596-3436, to set up interview times and photos.
AAC was discovered as a timber alternative in1920 by Dr. Axel Eriksson of the Royal Institute of Technology in Stockholm, Sweden. Currently there are more than 325 worldwide manufacturing plants that annually manufacture more than 25 million cubic yards. China is now in the midst of building more plants. Europeans have been using the material for the past 60 years; Russia is the greatest user. In the U.S., its presence has increased over the past 15 years.
AAC is workable and lightweight like wood. It can provide outstanding thermal insulation, is resistant to fire, termites and decay. A concrete product, AAC consists of finely ground sand, cement, quick lime, gypsum, aluminum and water. "Most sand is too coarse for the manufacturing of AAC," notes Mahgoub. Mills rotated by 500 horse power electric motors grind the grains up into a finer consistency, then pump the ground material into slurry tanks. The raw slurry is agitated constantly and mixed with water to hydrate the cement and to control the mix consistency. Aluminum paste or powder, mixed with water, is then introduced. The aluminum slurry is added to the mix and a chemical reaction produces a hydrogen gas that increases the mix volume. The result is a fine cellular structure of the finished product.
AAC can be used as roof, floor, vertical or horizontal wall panels, shaped into blocks and more.
The Concrete Industry Management Program at NJIT is designed to address the urgent need for professionals with the skills to meet the growing demands of a progressive, changing concrete industry. The program is part of a special curriculum in the NJIT Department of Engineering Technology in NJIT's Newark College of Engineering. The program prepares broadly educated, articulate graduates grounded in basic concrete construction management, who are knowledgeable of concrete technology and techniques.

NJIT, New Jersey's science and technology university, enrolls more than 9,558 students pursuing bachelor's, master's and doctoral degrees in 120 programs. The university consists of six colleges: Newark College of Engineering, College of Architecture and Design, College of Science and Liberal Arts, School of Management, College of Computing Sciences and Albert Dorman Honors College. U.S. News & World Report's 2011 Annual Guide to America's Best Colleges ranked NJIT in the top tier of national research universities. NJIT is internationally recognized for being at the edge in knowledge in architecture, applied mathematics, wireless communications and networking, solar physics, advanced engineered particulate materials, nanotechnology, neural engineering and e-learning. Many courses and certificate programs, as well as graduate degrees, are available online through the Division of Continuing Professional Education.

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
