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 ...
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 ...
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 ...
Measuring the in-situ compressive strength of concrete in final structures is an essential but challenging process. Coring combined with non-destructive rebound hammer measurements provides the most ...
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 ...
An increasing number of U.S. interstates are set to try out an invention that could save millions of taxpayer dollars and significantly reduce traffic delays. The invention, a sensor that allows ...
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 ...
