Concrete is one of the most widely used materials on the planet. "And this consumption comes with a heavy ecological price." Rouzbeh Shahsavari, a materials scientist at Rice University. "Around 5 to ...

Defect litigation presents a financial challenge to the concrete industry, and 2009 is unlikely to see any improvement in that regard. Whether fairly or not, concrete gets tainted by defects in other ...

A Schematic illustration of the auto-frequency-adaptive PLUS for 3D visualization of internal defects in concrete structures (left), and 3D imaging results of delamination in highly attenuative ...

Researchers created a high-resolution 3D ultrasonic imaging system for concrete that uses broadband ultrasonic signals to automatically adapt to different types of concrete structures. WASHINGTON, Jan ...

This is not a list of defects for architectural concrete formed surfaces. It's for any kind of structural concrete formed surfaces exposed to view. And that's a problem. Let's consider a few of these ...

Researchers in Japan and the US have developed a high-resolution 3D ultrasonic imaging system for concrete that automatically adapts to different types of structures. The advance by a team from Tohoku ...

Large concrete structures need to be regularly tested for defects that may compromise their stability. While acoustic tests performed by certified inspectors are usually the inspection method of ...

HOUSTON, Jan. 3 (UPI) --Calcium silicate hydrate, or C-S-H, accounts for the strength of cement and cement-based materials. It is the component of cement paste that holds concrete together.
