Until the mid-1970s, compression testing of composite materials received relatively little attention. Up to that point it, had generally been assumed that the compressive stiffness was approximately ...

Mechanical fasteners, such as screws, bolts, pins and rivets, have been used for hundreds of years to assemble wood and metal structures. As composites have replaced other materials in structural ...

There are a multitude of available test procedures and methods for water and wastewater treatment operators. They range from colorimetric, titrimetric, electrometric (meter & probe), turbimetric, ...

Along with the development of new instrumentation, the test procedure itself was also standardized. By “walking” the potential probe toward the current probe and graphing the measurements, the ...

When choosing a method for monitoring the compressive strength of concrete, it’s important for project managers to consider the impact each technique will have on their schedule. While some testing ...
