Nanoengineered concrete R & D to cut CO2 emissions

Nanoengineered concrete could cut CO2 emissions?

In a previous note on commercial or near commercial innovation, I recorded work on cement manufacturing at lower temperatures, thus saving energy and reducing CO2 emissions.

The MIT report (below_near the end of my entry) appeared to provide an opportunity to record both one high profile longer termed R&D work in Nanoengineering and the more mundane close to production, often overlooked by the main dailey press media.

Having recently received an invitation, among many others, to attend a 2 day conference, Global Fuels Conf. & Awards, held in London on 4-5 Feb. 08, [Link-html] reporting on Industrial progress and R&D work, many of which involved CO2 reduction in cement manufacturing, including it's use in steelmaking slags.


The following entry "Nanoengineered concrete could cut CO2 emissions? " which was my initial motivation to weblog, appears to belong to the longer termed (LT) research category unless the financial backing from the french company Lafarge pushes forward the project and in doing so achieve quicker and improved ROI-Return on Investment.

Nanoengineered concrete could cut CO2 emissions?
CAMBRIDGE, Mass.--While government leaders argue about the practicality of reducing world emissions of carbon dioxide, scientists and engineers are seeking ways to make it happen.
One group of engineers at MIT decided to focus its work on the nanostructure of concrete, the world's most widely used material. The production of cement, the primary component of concrete, accounts for 5 to 10 percent of the world's total carbon dioxide emissions; the process is an important contributor to global warming.

In the January issue of the Journal of the Mechanics and Physics of Solids, the team reports that the source of concrete's strength and durability lies in the organization of its nanoparticles. The discovery could one day lead to a major reduction in carbon dioxide emissions during manufacturing.

Could be worth repeating that the above reported MIT research was funded in part by the Lafarge Group according to

In guise of a conclusion:

May I take this opportunity to remind my readers that I travel for work missions only according to standard working request procedures, transportation mode being, of course, at the initiative of the requesting firm, however where distance is involved and when possible, rail travel is preferred. The latter is a considerable sacrifice, as I love flying!

1. With thanks to Danish Nano & Nilt News letter who drew my attention to this MIT
2. Global Fuels Awards
Four categories are open for nominations:

1 Outstanding alternative fuel project (cement or lime company)
2 Most innovative technology for alternative fuel use

3 Outstanding electrical energy efficiency project award (cement or lime company)

4 Most innovative technology for electrical energy efficiency
