E-Crete is on the Way
This week, the New Scientist reported on an eco-friendly new form of concrete, made from fly ash and slag removed from powerstations and steeleworks. The concrete is under testing in Australia.
Although its touted for its minimal greenhouse gas footprint, some of its longer term functional value may result from its more alkaline starting material. In particular, it may be possible that this concrete is less susceptable to the corrosive action of the various salts used in winter maintenance.
The latest research on the impact of road salts by the University of Toronto Civil Engineering graduate group under Professor Doug Hooton indicates that sodium chloride has the lowest impact on concrete corrosion. However, this new form of concrete may provide an even greater resistance to corrosion.
We can only hope.
