Green concrete made of rice husks
If you are an early reader of this blog you perhaps remember my article on how aerogel, a fantastic material could be made of rice husks. Now comes another great use of this by-product of the most consumed cereal. To Discovery Channel:
A new way of processing rice husks for use in concrete could lead to a boom in green construction. Rice husks form small cases around edible kernels of rice and are rich in silicon dioxide (SiO2), an essential ingredient in concrete.
With less CO2 emissions than traditional concrete, this construction material could seriously help Asian and African nations to limit their greenhouse gases emissions coming from the building sector.
