When people hear the term “slump,” most think about posture; think of concrete slump as "concrete posture." In technical terms, slump is a measured indication of the workability, or flow, of a mix.

Some basic NDT techniques utilized to assess concrete structures include:Once concrete has hardened, it is important to determine whether the final structure is suitable for its designated use. To do ...

Engineers have developed a new test that can predict the durability of cement in seconds to minutes -- rather than the hours it takes using current methods. The test measures the behavior of water ...

A solid concrete structure may probably fail if gaps are not properly bridged and protected. When the concrete structure serves as a containment vessel of fluids, leakage must be prevented or reduced ...

Concrete sample undergoing strength testing Carelle Mulawa-Richards/RMIT Using organic waste-enhanced concrete could mean construction cost savings. “Our research creates a potential to even reduce ...

Read about an industrial densifier/hardener performance test conducted by the CTL Group and Mark Wetherell. The test measured abrasion resistances of four different densifier types in accordance with ...

Controls' Automax 5 series of Concrete Testing equipment features a fully automatic test cycle with a closed loop retraction. The load/time graph and the gradient are displayed in real time, while the ...

A concrete-testing laboratory faked results for a LaGuardia Airport control tower, the new Yankee Stadium, the Lincoln Tunnel and more than a dozen other projects around the city, creating thousands ...

Experimental concrete that patches up cracks by itself is to undergo outdoor testing. The concrete contains limestone-producing bacteria, which are activated by corrosive rainwater working its way ...
