The collapse of the 200 m section of the Ponte Morandi in Genoa, Italy, in heavy rain last week has generated fierce debate about infrastructure and the maintenance of bridges, in particular. Designed by Riccardo Morandi and completed in 1967, major repairs were carried out in the 1990’s and restructuring work was done in 2016. A local structural engineer warned about problems around the same time. But Monash University senior lecturer in civil engineering says, despite the incident, “bridges are the safest of all major structures – more so than buildings and dams”.

Size diversity in cement nanoparticles
Size diversity in cement nanoparticles21 Jun 2018

In new work, researchers found that the size of C-S-H particles themselves is also somewhat disorderly: The particles form at random sizes, not in homogenous spheres, and this diversity in the size of the nanoscale units leads to a denser, disorderly packing of the particles, which corresponds to stronger cement paste.

The researchers hope this understanding will allow materials scientists and concrete engineers to alter the C-S-H particles at the molecular level to develop stronger, more durable concrete that will have a reduced environmental footprint. If concrete is stronger, less of it is needed. And if it’s more durable, structures made from it will last longer...More
