Sugar cane to make self-healing concrete/Caña de azúcar para fabricar un hormigón autorreparable

Cement and concrete are the most popular elements used in the construction of all types of buildings and infrastructure, which is why according to existing data it is estimated that around four billion tons of cement alone are consumed annually in the world, which gives a idea of the number of uses we give to this material.
El cemento y hormigón son los elementos más populares utilizados en la construcción de todo tipo de edificios e infraestructuras, por eso según los datos existentes se calcula que en el mundo se consumen anualmente unos cuatro mil millones de toneladas solo de cemento, lo que da una idea de la cantidad de usos que le damos a este material.
But cement has a problem, it is not eternal and needs maintenance, over time cracks occur that not only affect the aesthetics but also pose a risk of collapse if proper maintenance is not done, in fact it is estimated that hundreds of billions of dollars annually worldwide in the maintenance of these structures.
Pero el cemento tiene un problema, no es eterno y necesita mantenimiento, con el tiempo se producen grietas que no solo afectan a la estética sino que supone un riesgo de derrumbe si no se hace el mantenimiento adecuado, de hecho se estima que se gastan cientos de miles de millones de dólares anualmente en todo el mundo en el mantenimiento de estas estructuras.

That is why it is normal to investigate new technologies that improve the quality of cement by mixing it with different materials. Of all those used, the one that seems to take the cake is sugar cane bagasse, bagasse is the fibrous residue resulting from process applied to sugarcane for the extraction of its juice.
Por eso es normal que se investigue en nuevas tecnologías que mejoren la calidad del cemento mezclándolo con distintos materiales, de todos los utilizados el que parece que se lleva la palma es el bagazo de la caña de azúcar, el bagazo es el residuo fibroso resultante del proceso aplicado a la caña para la extracción de su jugo.
A team of researchers from Kohn Kaen University and Suranare University of Technology in Thailand are developing cane biocement, which they have called IBFC, and have found that mixing the cement with sugarcane waste and a certain type of bacteria this acquires the ability to seal cracks and self-repair.
Un equipo de investigadores de la Universidad de Kohn Kaen y la Universidad Tecnológica de Suranare de Tailandia, están desarrollando el biocemento de caña, al cual han llamado IBFC y han encontrado que mezclando el cemento con residuos de caña de azúcar y un cierto tipo de bacterias este adquiere la capacidad de sellar las grietas y autorrepararse.

The bacteria added to the mixture are called Lysinibacillus and it is these bacteria that give this cane bagasse bio-cement the superpower of repairing itself like in science fiction movies, and apparently more than a thousand million tons of sugarcane bagasse are generated worldwide that will now can have a new use.
Las bacterias añadidas a la mezcla son las llamadas Lysinibacillus y son estas bacterias las que dan a este bio-cemento de bagazo de caña el superpoder de repararse a sí mismo como en las películas de ciencia ficción, además según parece mundialmente se generan mas de mil millones de toneladas de bagazo de caña de azúcar que ahora tendrá un nuevo uso.
But you already know that, as usually happens, these are only laboratory experiments and there is still a lot to investigate to know how these bacteria behave in the long term or if they can even be harmful to us, even so it is good that they continue looking for solutions because the construction fever does not seem to be slowing down.
Pero ya sabéis que, como suele pasar, esto tan solo son experimentos de laboratorio y todavía queda mucho que investigar para saber como se comportan esas bacterias a largo plazo o si incluso pueden ser perjudiciales para nosotros, aún así esta bien que sigan buscando soluciones ya que la fiebre de construcción no parece que se vaya a frenar.

That is another wonderful discovery that will really help our society I am so sure of that certainly
Actually if this new discovery can really be experimented and proven to be true, it will really go a long way in helping the world of construction I must confess

I am actually loving this new discovery and how it is really working so much. Science is working massively
This is actually the first time I am hearing about this update and I must say it is really a great update if well maintained. Well let's see how it will actually goes around
