White Spots On Teeth After Whitening

Construction: Concrete, translucent latest invention Mexican [Teodoro González de León, Sordo Madaleno, Cesar Pelli, Zaha Hadid, Rem Koolhaas].


is likely that in the coming years the construction of houses and buildings are carried out with a new material invented by two Mexican universities: the translucent concrete. This product allows up walls almost transparent, stronger and lighter than traditional concrete.


A revolutionary invention. Mexican civil engineers, Joel Gutiérrez-Sosa 26 years, and Sergio Galvan Omar Cáceres-25-year-created in the 2005 this revolutionary cement has the ability to be cast under water and be 30 percent lighter than concrete so far known. One of the inventors, said Sergio Galvan, translucent concrete is more aesthetic than conventional saves finishing materials [such as plaster, paint and varnish] and has the same utility. According to the sales brochure of the product, its manufacture is equal to that of regular concrete. We used white cement, fine aggregate, coarse aggregate, fiber, water and additive whose formula is secret, known-Ilum.


"Your workmanship is equal to that of regular concrete .- In addition, this new specific objects can be introduced, lighting and pictures, as it has the virtue of being translucent to two meters thick, with no obvious distortion. This product represents a breakthrough in the construction of offshore platforms, dams, sea walls and embankments in coastal areas, because its components do not deteriorate under the water. The additive-Ilum-is unique in the world, which gives the concrete strength 15 times -4.500 kg/cm2- with no water absorption, allowing the passage of light, is translucent, has a 30 percent volume weight commercial below and can be cast under water. Currently the authors are in the process 15 applications for patent in the country at the Mexican Institute Industrial Property [GRI] and four internationally. They also seek to patent the product in Japan, China, India, USA, South America and the European Union. One of these patents, a high strength cement, was signed in joint ownership with the UAM. The relevant contract settles to the proceeds divided equally between the institution and the inventors. Students reported that the helipad of the new fire station will be built with concrete Ilum and which are already signs the contract with the authorities of the Federal District Government through the Heroic Body Donor Trust AC and Phoenix. The impact of this technological development allowed students form the translucent concrete company SLR de CV, which has been supported by the National Council of Science and Technology [Conacyt] for over a year with 7.5 million dollars for patent certifications and paperwork. The Italian cement Italcimenti has made an offer to buy the company. CONACYT has classified this project as the fourth best in the past six years in the area of \u200b\u200bScience and Technology, in addition to being the youngest program supported by the body, as well as Joel Sosa Sergio Galvan still completing their undergraduate studies.
