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.

What is new is that as the headwall was printed, a lidar unit made precise scans of the structure, building up a digital virtual twin against which the real thing can be compared. Also, wireless ...

In hopes of producing concrete structures that can repair their cracks, researchers from Drexel University’s College of Engineering are putting a new twist on an old trick for improving the durability ...
