Scientists are seeking ways to use cement more efficiently and reduce the carbon emissions associated with its manufacture. They have revealed new properties of the mineral tobermorite. Using x-ray-diffraction to probe its crystalline structure, which corresponds to Portland cement's most important component, they squeezed the mineral in a diamond anvil cell to pressures equivalent to 100 miles deep in the earth.

"Portland cement is the most important building material in the world,” says Paulo Monteiro, University of California at Berkeley, "but if we are going to find ways to use it more efficiently - or just as important, search for practical alternatives - we need a full understanding of its structure on the nanoscale.” To this end Monteiro has teamed with researchers at the U.S. Department of Energy's Advanced Light Source (ALS) at Lawrence Berkeley National Laboratory. The results of their experiments led to new insights into calcium-silicate-hydrate, the material primarily responsible for the strength and durability of concrete made with Portland cement.
