3D concrete printing is one of the technology disruptors with the potential to radically redefine construction methodologies by accelerating the pace of construction and significantly improving build quality. We have successfully 3D printed a G+1 (Ground plus one) building with reinforcement for the first time in India.
In 3D printing, the material is printed under computer control to build a 3- dimensional product, typically layer by layer. The concrete mix design requires a paradoxical combination of concrete properties like flowability, quick hardening to take the load of subsequent layers, green concrete status to ensure bonding between the layers, and strength to print successfully. Cast in Situ’ at the job site in an ‘open to sky’ environment, we 3D printed the building in 106 printing hours, using a fully automated 3D printer.
Earlier in November 2019, we 3D printed a 240 sq feet 1 BHK, in line with typical EWS building layout, to explore the feasibility of this innovative technology.
