New concrete captures carbon and is stronger and lighter

New developments in concrete production have made concrete that is stronger and lighter than conventional concrete and has carbon capturing properties. According to the Whole Building Design Group, the goals of sustainable building design are: “To reduce, or completely avoid, depletion of critical resources like energy, water, land, and raw materials; prevent environmental degradation caused […]

3D printing used to fabricate concrete slab

4th August 2018 by Sean Couldwell Concrete 0 Comments

Researchers at ETH Zurich University have fabricated a lightweight concrete slab using 3D printing, which is the first time 3D-printed concrete has been used in a full scale architecture project. The 80 square metre slab is only 20mm thick at its thinnest point and forms a concrete ceiling with decoratively ribbing. The slab is the […]

3D print experts experiment with concrete

Research is currently being undertaken to print 3D objects in concrete, perhaps literally paving the way for concrete flooring to be produced in an entirely different way. The building contractors Skanska is working with a number of partners to develop 3D printing of concrete. Loughborough University started researching 3D concrete printing in 2007 a year […]
