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 ...

Concrete is an essential construction material that is used globally. Combining coring and rebound surveys provides the most efficient and cost-effective method of assessing in situ concrete 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, ...

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 ...

As more and more wind turbines pop up across the state and country, researchers at Iowa State University are studying a new way to build the towers that hold them up into the sky. Grant Schmitz, a ...

Concrete is the most widely used building material on Earth, and its key ingredient, cement, accounts for roughly 8% of ...
