Andrey Rudenko's 3D-printed castle

Though 3D printing technology is still relatively new, it may become an important tool for architects and the construction industry, as highlighted by projects like the recent 3D-printing of 10 homes in a day. The latest example of this progress comes via US-based Andrey Rudenko, who has created a small concrete "castle" structure in his backyard using a large 3D printer he built himself. Next up, he's making a house.  Read More

The Seaside Periscope, by Adam Wierciński (Image: Adam Wierciński Architekt)

It's no easy task for an architect to put his or her stamp on basic facilities like public restrooms. Architect Adam Wierciński has managed it though, and his Seaside Periscope concept comprises a public toilet that sports a working periscope system.  Read More

A concrete beam coated with the skin (above), and a computer map of the cracks in it

Although concrete structures such as bridges are now often built with strain sensors embedded within them, that certainly hasn't always been the case. In order to alert authorities to cracks developing within these older structures, one solution involves attaching sensors to them. Researchers from North Carolina State University and the University of Eastern Finland are working on an alternative, however – an electrically-conductive paint-on "sensing skin."  Read More

House for Trees, by Vo Trong Nghia Architects (Photo: Hiroyuki Oki)

Like many inner-city residential areas, the Tan Binh district in Vietnam's Ho Chi Min City is rather lacking in greenery. Local firm Vo Trong Nghia Architects sought to make daily life more comfortable for one family by constructing something of a private oasis within the bustling metropolis.  Read More

Inside a test dome built using the pneumatic wedge method

There probably aren't many domed concrete structures where you live, and there's a reason for that – they're difficult to build. Doing so usually requires the construction of a supporting wooden structure, that holds the concrete in place while it hardens. Now, however, a team at the Vienna University of Technology has devised a system that allows concrete shell structures to simply be "inflated" and cinched together with a steel cable.  Read More

Taizhou Bridge under construction

The 2,940-m long Taizhou Bridge has won the Supreme Award for Structural Engineering Excellence at this year's Structural Awards. The event gives the nod to a variety of structures across numerous categories, but it was the three-tower, long-span suspension bridge, the first of its kind, which received the overall "Supreme" gong. Read more about the project and the individual category winners after the cut.  Read More

The 36-story Ardmore Residence in Singapore designed by Dutch firm UNStudio heralds a "new breed" of residential skyscraper for the region. Employing an innovative inter-locking system of construction, the building features a distinctive, organically-inspired facade and a design concept focused on the natural landscape of the Garden City of Singapore.  Read More

The gesture-controlled PACO concrete speaker from Digital Habit(s)

Visitors to the homes of audio buffs might well be surprised to find weighty blocks of concrete breaking up the living room's otherwise colorful designer decor. These high-end music lovers have turned their backs on the unwelcome distortion and color that can be caused by oscillations of MDF, wood or plastic speaker cabinets, and plumped for drivers housed in concrete. If you can't afford, or don't have room for, large commercially-available floor-standing units like the exquisite N1 loudspeakers from Germany's Concrete Audio, Italy's Digital Habit(s) design house has created a gesture-controlled, Bluetooth-enabled tabletop speaker called PACO, which can be built at home using open source plans, or bought fully assembled.  Read More

The self-healing-concrete would fill cracks and prevent decay and the corrosion of rebar (...

You’d think that concrete would last forever. After all, it’s pourable stone, so it should hang around as long as the Rock of Gibraltar. But, under the right (or wrong) conditions, concrete decays with alarming speed. To combat this, researchers at the University of Bath in the UK are working on a self-healing concrete that uses bacteria to seal the cracks that lead to decay. In this way, they hope to cut down on maintenance costs and increase the life of concrete structures.  Read More

Engineers at Iowa State University think concrete columns could be the key to building taller, higher-powered wind turbines. By making the switch from steel to concrete, it's thought that the upper limit of turbine column height could be raised from 80 m to over 100 m.  Read More
