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.

Extracting the secrets of ancient masons—Maya plasters owe their strength to plant-induced biomimetic structure

By Lisa McDonald / June 20, 2023

Like Roman concrete, plasters from the ancient Maya civilization are another historical building material that researchers are trying to understand and replicate. In a recent open-access paper, University of Granada researchers used advanced imaging techniques to reveal that the addition of organic molecules to the Maya plasters induced the formation of biomimetic structures, which are likely key to the plaster’s durability.

Let there be light—aerogel-filled glass bricks provide translucency as well as insulation and loadbearing capabilities

By Guest Contributor / June 9, 2023

Glass block walls can be a desirable way to maximize natural light exposure in a building, but their thermal properties do not allow for the best energy efficiency. Researchers at Empa, the Swiss Federal Laboratories for Materials Science and Technology designed aerogel-filled glass bricks that are translucent as well as thermally insulating and strong.

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.
