We are always looking for more environmentally friendly ways to work, and a recent dissertation by Johanna Tikkanen of the Aalto University School of Engineering near Helsinki in Finland, could lead to big developments in the future.
The idea of the paper was to study how different mineral powders could be used as replacements for the cement, the creation of which is one of the main contributors to the amount of CO2 emitted during the manufacturing process. Replacing or simply reducing the amount of cement in the concrete will lower the amount of CO2 used significantly, and will also reduce the cost of manufacturing. Mineral powders can also be used to reduce the water requirements of concrete, further adding to the economic and environmental benefits.
Obviously, the properties of the cement will have to remain roughly the same, so that the concrete can be used in the same processes as before, but if it can be perfected, then concrete production will be greener than ever before.
