CYPRESS, CA -- (Marketwire) -- 06/19/12 -- CTS Cement Manufacturing Corporation -- the leading manufacturer of specialty fast-setting hydraulic cement and shrinkage compensating cement -- has announced the discovery of new structures in cement.
Discovered in mixtures of coal fly ash and hydrated calcium sulfoaluminate cement, these intriguing structures consist of micron-sized glass spheres upon which needles have grown radially. Whereas these needles usually grow randomly in Rapid Set® cement, they organize themselves as spines on round fly ash particles in fly ash/cement mixtures.
According to Dr. Eric Bescher, Vice President for Cement Technology at CTS Cement, this is the first time these complex structures have been seen. These structures are very small, typically a few tens of microns in size and can only be seen clearly under an electron microscope.
"We are excited about discovering these new self-organized inorganic architectures, said Bescher. "Think of these structures as micron-sized sea urchins shells embedded in cement paste. We have some indications that they may play a beneficial role in the reinforcement of concrete or in shrinkage mediation. Our work is in progress and we are investigating the influence they could have on other properties of construction materials."
CTS Cement is not aware of reports on similar structures in scientific literature to date. It is possible these structures grow and develop only in calcium sulfoaluminate/fly ash mixtures. Bescher explains that the discovery is the result of attempts to make the already green Rapid Set even greener. "By substituting some of the Rapid Set cement with fly ash, we will further reduce the already minimal carbon footprint of the cement while finding a use for a waste material," said Bescher. "In this process, we stumbled onto something unexpected and exciting, the significance of which is to be determined."
CTS Cement is in the process of further investigations on the so-called self-organized BescherBalls to understand their significance and the role they can play in construction materials. BescherBalls is the working name for these innovative structures. "We have much more to learn about this ingenious design and the formation mechanism of these structures," says Bescher. "Our research teams are hard at work."
Jerry Hoyle, CTS President, noted that this discovery will likely offer the design and construction industry a new alternative for specifying concrete as a green solution.
"As a long-time leader in the concrete industry, we are excited that our commitment to research and development efforts has provided new opportunities for our marketplace," said Hoyle. To learn more about BescherBalls, contact Janet Ong at email@example.com.
