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 ...
Currently, the rebound hammer is widely used for estimation of compressive strength of concrete as general testing method. Although rebound hammer has made great contribution for compressive strength ...
So that it may be certain that a concrete specimen’s mechanical properties reach the strength and deflection imperatives for its intended use, concrete specimens with specific dimensions are prepared, ...
States consider new science-backed solution to save time and money on concrete infrastructure repair
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 ...
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 ...
Sensors from the WaveLogix REBEL Concrete Strength Sensing System, seen here at a road construction site in Tennessee, help detect road strength in real-time. Submitted photo Sensors that could change ...
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 ...
States consider new science-backed solution to save time and money on concrete infrastructure repair
Following seven years of research, approval of this Purdue-developed technique as a standard by the American Association of State Highway and Transportation Officials is an initial step toward the ...
