Concrete is a complex material made of just four basic ingredients: coarse
aggregates (stone), fine aggregates (sand), water, and cement. It is
extremely hardy and maintenance free, leading to buy viagra using paypal some claims that it is a green
material. But cement is incredibly energy intensive to produce.
Minerals must be fired in ovens at temperatures of 1500 degrees C (over
2700 degrees F). Because concrete is www.unifem.it used so frequently cement manufacture is actually responsible for an
estimated 5 to 10 percent of all carbon dioxide released to the
MIT researchers have been examining the structure
of concrete in an attempt to better understand how the material works
and to develop better (and less energy-intensive methods) for
Cutting back on cement production, or finding a cleaner way of producing
it could be a huge step in reducing greenhouse gasses in the atmosphere.
It may not be as cool as light
transmitting concrete, but it has a much greater potential to be a
useful contribution towards a greener world.
