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 ...

American Association of State Highway and Transportation Officials’ Committee on Materials and Pavements approves Purdue-invented method as a national standard for estimating concrete strength WEST ...

Consider the following scenarios for a project on which the specified compressive strength (fc’) is 3,500 psi at 28 days. These are all examples of incorrect interpretations of the acceptance criteria ...

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.

If structural engineers have their way, building codes will take a leap forward in the next couple of years to allow the use of higher-strength 80-ksi reinforcing steel in concrete shear walls in high ...

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 ...
