Lab Generated Lightening Creates Recycled Concrete
Reuse,recycle are the working themes these days. Scientists are now working in segregating core components from rubble by striking lab created lightening. The core components can be used again to erect new buildings from the waste.Millions of tons of concrete is created every day because of demolition of old buildings.
Scientists at the Concrete Technology Group, Fraunhofter Institute,Holzkirchen,Germany,wanted to create a way to truly recycle the concrete.
Russian scientists discovered a process called electro dynamic fragmentation that breaks things down to its original components.
Using the principle of dielectric strength,the Fraunhofer researchers discovered that a 150 nanosecond bolt of lightning traveling through water can actually enter concrete. When hit with that short,intense bolt of lightning,it will pass through the water into the concrete using the paths of least resistance which would be through the bonds between the components of the concrete which are cement, aggregate rock and water.
This process takes the concrete down to its raw components again,not just messy rubble. Having the raw components reborn out of the explosion allows engineers to make brand new concrete.
Currently,the researchers can process one ton of concrete waste per hour in their laboratory fragmentation plant.
