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 ...

Although failure of material is not the only reason for bridge failures, it is a vital step for choosing the correct materials, the analysis of bridge design, and construction testing. Bridge members ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

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 ...

Drexel University engineers have shown that a concrete mix designed to gently warm itself in cold weather can cut damaging freeze-thaw cycles outdoors, pointing to longer-lasting pavements for cold ...

Ultra-high-performance concrete (UHPC) is rapidly emerging as a premier material for precast concrete construction. First introduced as “reactive powder concrete” in the early 1990s, this material has ...
