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, ...

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 ...

The principle of concrete maturity offers a non-destructive approach to estimate strength, crucial for timely decisions in ...

Pueblo Chemical Agent-Destruction Pilot Plant workers have been testing and placing self-consolidating concrete, or SCC, that will be used in the walls of the Explosive Containment Room of the ...

This "self-healing" and "self-heating" bendable concrete is the next generation of infrastructure material, Michigan State ...

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 ...
