Back in April 2015, my CW column focused on the two ASTM standardized test methods used for measuring the through-the-thickness, or interlaminar, tensile strength of composite laminates. Despite their ...

One material property that is widely used and recognized is the strength of a material. But what does the word "strength" mean? "Strength" can have many meanings, so let us take a closer look at what ...

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 ...

In my previous column (see “Editor's Picks,” at right), I discussed transverse flexural testing of a unidirectional composite as one method of evaluating the strength of the fiber/matrix interfacial ...

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 have found that mixing jute fibers with bacteria can make concrete stronger and more durable—offering a greener, low-cost way to fight cracks and wear over time.
