Not all damage to a load-bearing structure is immediately apparent. So how do civil engineers find out that a bridge or a large hall is no longer safe? Many clues form a picture. Concrete structures ...

When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

How long it takes to construct a building depends in large part on when the concrete of each floor is strong enough to take on loads. Purdue University engineers have developed sensors that could ...

The principle of concrete maturity offers a non-destructive approach to estimate strength, crucial for timely decisions in ...

This study presents a concrete mix using agro-industrial waste, achieving 38.8% lower emissions and improved strength, paving ...

Researchers aim to gauge how buildings constructed with reinforced concrete withstand an earthquake by conducting a simulation test at a two-story building built in the 1920s in El Centro, Calif.

AMES, Iowa – Grant Schmitz, eyes inches from a 6.5-by-12-foot panel of ultra-high performance concrete, studied the smooth surface for tiny cracks. He and other research engineers carefully marked ...
