Concrete

Left to right: Roland Pellenq of the Department of Civil and Environmental Engineering (CEE), Katerina Ioannidou of the MIT Energy Initiative, and Franz-Josef Ulm of CEE have developed a detailed understanding of the nanoscale forces at work as cement hardens — a critical step toward developing stronger, longer-lasting, less carbon-intensive concrete for “greener” construction in the future.

MIT Concrete Sustainability Hub principal investigators Franz-Josef Ulm and Roland Pellenq and research scientist Mehdi Akbarian run a pavement-vehicle interaction test that simulates a vehicle moving over pavement. The test determines excess fuel consumption induced by pavement material and structural properties.

Well-maintained roadways improve fuel efficiency

Research aims to encourage decision makers to think of infrastructure as part of the solution in a carbon constrained environment.

$This image of a simulated concrete sample shows the "packing fraction" which describes the fraction of the volume that is filled with solid material. In this case, the average packing fraction is 0.52. Colors indicate the variations within the sample, ranging from less than 0.4 to more than 0.64. The size of the cube is 0.6 microns (millionths of a meter).$

Riddle of cement’s structure is finally solved

Findings may guide development of formulas to make the material more durable, less CO2-intensive.
