Deakin researchers develop concrete solution for recycled glass | Deakin
some types of colored glass aren't recycled due to the difficulty in cleaning it up to clear again, so being able to use it elsewhere is a plus as an alternative to high grade sand. But this is polymer resin based concrete (substituting cement) so that's a different problem...

Novel ecosustainable peat and oil shale ash-based 3D-printable composite material - ScienceDirect
Using milled peat and oil shale ash to make cheap 3D printed bricks. The oil shale ash has high pH, making it work well as a binder. Though the bricks take a day to harden up though...

MX3D Bridge
Freaky looking freeform-esqe (not some genetic algorithm evolved parametric minimalist design) 3D printed bridge. Trying to develope in-situ printing, which is a whole 'nother beast, and might have some metal grain issues, but since this is a small pedestrian bridge you can probably fake it by overbuilding a bit. Seems to use a generic robot arm with a MIG welder on the head?

Enhancing Mechanical Properties of Pervious Concrete Using Carbon Fiber Composite Reinforcement | Journal of Materials in Civil Engineering | Vol 30, No 3
permeable concrete normally sucks, but throwing ground up waste carbon fiber into it makes it strong enough for actual usage, particularly for road/ground cover where you want rain water to pass though into the ground reasonably quickly, rather than collecting pollution then ending up in storm sewers..

Using the whole house/roof as a sun tracker is kinda interesting, when the interior walls are exposed to exterior lighting in the daytime, but sealing up at night for better insulation?

Masonry from industrial waste
Interesting ambient temperature curing bricks, using boiler ash and alkali chemical curing. Regular brick manufacturing uses 1000C kilns, which use a lot of energy/fuel.

Kra Canal (Thailand) excavation by nuclear-powered dredges
Considering the current existence of the russian nuclear power barge, a nuclear dredger isn't wholly insane. But, considering it would be operating in foul water due to kicked up sediment, conventional sea cooling probably isn't available, limiting power generation ability. Doubt you want to use an air cooled reactor on a ship either...

Turning billboards into homeless housing. For people who don't want a lot of windows (or prefer skylights), this actually isn't a terrible design on it's own. As a homeless rehousing concept, shifting them to the highway seems like trying to hide the problem more, along with poor access.

Empa - Shape Memory Alloys - A shape-conscious alloy
Low temp iron based SMA's make SMA reinforced prestressed concrete beams practical, which can be prestressed without elaborate tensioning systems. The only issue is the 160 degree transition temperature means if such a beam ever got exposed to a vehicle fire, it might fail faster than conventional prestressed concrete using steel rebar...
