Concrete reabsorbs some of its carbon emissions over time. Alternative ingredients and 3D printing could help supercharge that by making the finished concrete more porous.

Structures are designed for 50 to 100 years, depending on the requirements. Many civil engineering structures that are part of Dutch infrastructure are now over halfway through their service life, and ...

This unconventional structural system was inspired by the material in question: as unreinforced concrete has poor tensile strength, it is unsuitable for use in a cantilevered system as used in many ...

Large concrete structures need to be regularly tested for defects that may compromise their stability. While acoustic tests performed by certified inspectors are usually the inspection method of ...

When bridges, dam walls and other structures made of concrete are streaked with dark cracks after a few decades, the culprit is AAR: the alkali-aggregate reaction. AAR damages concrete structures all ...

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 ...

Three poured-in-place concrete structures, each 100 square feet — and each with its own unique characteristics — are scattered within close proximity on a rocky, scrubby, 5-acre site in California’s ...
