Luminescent material offers real-time analysis of concrete deterioration

By Lisa McDonald / January 30, 2024

Determining the degree of carbonation in a concrete structure allows for timely maintenance to avoid catastrophic failure. Researchers led by the University of São Paulo’s Physics Institute developed a luminescent material that can indicate the degree of carbonation in concrete structures in a nondestructive manner.

Embodied carbon of concrete in buildings: Large-scale study calls for more consistency and accuracy in reporting of carbon impacts

By Lisa McDonald / July 14, 2023

Players in the cement and concrete sectors are working diligently to achieve a reduction in emissions. However, there are multiple gaps in knowledge about the extent of these emissions, which makes it difficult to determine how effective new initiatives are at reducing emissions. A group of researchers from several universities in the United Kingdom are conducting a large-scale study to help fill this knowledge gap.

Aerated concrete: A ‘pore’fect tool in the construction industry’s advance toward sustainability

By Guest Contributor / May 16, 2023

Reducing the amount of raw material needed to produce concrete is one way to help cut emissions in this industry. Aerated concrete, a lightweight and porous construction material, contains less raw material per volume than many other building products. Today’s CTT contains a brief overview of this material, including its history, production methods, applications, and ways to improve its end-of-life sustainability.

Low-carbon cement technology heading from lab to market

By Guest Contributor / March 24, 2023

The recent one-year anniversary of the National Science Foundation’s Directorate for Technology, Innovation, and Partnerships is a reminder of the federal government’s commitment to take a larger role in supporting the transition of use-inspired research from the lab to the marketplace. Ideally this support will allow more university researchers to follow in the footsteps of Sublime Systems, a spinout from the Massachusetts Institute of Technology that aims to commercialize a low-carbon cement technology.
