In the field of additive manufacturing, 3D printing with concrete is one of the more special fields. Compared with traditional methods, it still has the advantages of optimizing material use and cutting costs. However, the 3D printing mixture needs to exhibit consistent fluidity and low viscosity in order to avoid the "sagging" phenomenon, thereby losing shape stability and dimensional accuracy. A group of researchers from Delft University of Technology in the Netherlands formulated a
According to the website of The Architect’s Newspaper，The Provincial Centre for Sustainability and Innovation in Construction (better known as Kamp C) in the Belgian municipality of Westerlo has completed work on a two-story model home, measuring just shy of 970 square feet, that was produced as a single piece by a fixed 3D printer—a world’s first. The concrete printer in question is also Europe’s largest.
Recently, according to a report of foreign news, the researchers of Brunel University London designed a new mixture of concrete which can absorb less 64% water and 90% salt than common concrete, but the strength can be 42% higher.
Recently, the Indiana Department of Transportation (INDOT) entrusted a team of Purdue engineers to embed sensors into the Indiana highway to more accurately determine when concrete pavements were ready to take on heavy truck traffic,
