ACT Concrete Restoration chief executive Andrew Ivers, who has worked in the Canberra industry for 30 years, also said demand ...

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 ...

Rock-filled concrete (RFC) construction technology is to construct a force-transferring skeleton with large-size rocks, and to use self-compacting concrete (SCC) as the filling and bonding material.

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 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 ...

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 ...

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 ...

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.

In recent years, many scholars have investigated the effects of concrete strength, integrity, and mud content on strength through ultrasonic technology, and many research results have been achieved.
