When compressive strength tests of laboratory-cured cylinders fail to meet the specified acceptance criteria, core tests are commonly used to verify the strength and to obtain acceptance of the ...

Results that are obtained from concrete specimens during laying of concrete may not actually represent the concrete strength in the structure. In situ NDT (non-destructive testing) at several ...

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 ...

A shortage of skilled labor continues to be the dominate issue in the construction industry, and rightfully so. However, delays in construction schedules have always been a thorn in the side of ...

As infrastructure ages, one question shapes the future of cities: How do we know the materials we build with will last? Subscribe to our newsletter for the latest sci-tech news updates. At the ...

Drexel University engineers have shown that a concrete mix designed to gently warm itself in cold weather can cut damaging freeze-thaw cycles outdoors, pointing to longer-lasting pavements for cold ...

Ultra-high-performance concrete (UHPC) is rapidly emerging as a premier material for precast concrete construction. First introduced as “reactive powder concrete” in the early 1990s, this material has ...
