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
