Mexican researcher creates cement that makes lightBy Valeria Bigurra Peñavera
Cement is a material that is present in the majority of buildings. A Mexican scientist decided to create something that would allow this material to be also used as source of light.
The chemical composition of materials that have this feature, is in fact what determines the color of the emitted light. This cement, which particularly emits light, had to have specific changes to its
the cement that emits light had changes in its molecular structure, using inorganic chemistry, and from river sand, industrial waste steel, alkalis and water.
This cement - developed by a gel hydrated calcium silicate, lime crystals and dispersed as calcium needles sulfaluminates networks - not only can be used as an adhesive, but also as a construction material, and a light source at the same time.
In an interview with the news agency of the National Council of Science and Technology (CONACYT), José Carlos Rubio Avalos said his development aims to be a new alternative in construction, and simultaneously have a low environmental impact.
European companies have shown interest in patenting the project, since one of its greatest advantages is that in order to make it work all you need is a source of light –whether artificial or natural-, and there’s no need for wiring or electric installation. This in fact, makes the entire project very practical.
Stated in the press release by CONACYT, the researcher ensures that the material has a rather broad number of uses and applications, especially within the architectural market. Additionally, it can benefit areas that need lighting, or spaces that have no access to electrical installations.
He also said that it is estimated that the durability of the cement light emitter is approximately 100 years, plus it is easily recyclable due to its material components.
