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, ...

Concrete is the most used construction material in the whole world. More than that, behind water, it’s the most used material, all categories combined. Worldwide, about 10 billion tons of concrete are ...

Researchers from North Carolina State University have, for the first time, used a "micropillar compression" technique to characterize the micro-scale strength of cement, allowing for the development ...

A group of students and advisors pose in front of a table that holds some concrete test samples. width=640 srcset= 1000w, ...

A solid concrete structure may probably fail if gaps are not properly bridged and protected. When the concrete structure serves as a containment vessel of fluids, leakage must be prevented or reduced ...
