SCRIM: An Innovative Method for 3D Concrete Printing

SCRIM is a novel hybrid construction concept, namely Sparse Concrete Reinforcement In Meshworks (SCRIM), that intersects robot-based 3D Concrete Printing (3DCP) and textile reinforcement meshes to produce lightweight elements. In contrast to existing 3DCP approaches, which often stack material vertically, the SCRIM approach permits full exploitation of 6-axis robotic control by utilizing supportive meshes to define 3D surfaces onto which concrete is selectively deposited at various orientation angles.
Also, instead of fully encapsulating the textile in a cementitious matrix using formworks or spraying concrete, SCRIM relies on sparsely depositing concrete to achieve structural, tectonic and aesthetic design goals, minimizing material use. The motivation behind this novel concept is to fully engage the 3D control capabilities of conventional robotics in concrete use, offering an enriched spatial potential extending beyond extruded geometries prevalent in 3DCP, and diversifying the existing spectrum of digital construction approaches. The SCRIM concept is demonstrated through a small-scale proof-of-concept and a larger-scale experiment.

Scientists Pioneer a New Way to Turn Sunlight into Fuel
The quest to find new ways to harness solar power has taken a step forward after researchers successfully split water into hydrogen and oxygen by altering the photosynthetic machinery in plants. Photosynthesis is the process plants use to convert sunlight into energy. Oxygen is produced as by-product of photosynthesis when the water absorbed by plants is 'split'. It is one of the most important reactions on the planet because it is the source of nearly all of the world's oxygen. Hydrogen which is produced when the water is split could potentially be a green and unlimited source of renewable energy.

A new study, led by academics at St John's College, University of Cambridge, used semi-artificial photosynthesis to explore new ways to produce and store solar energy. They used natural sunlight to convert water into hydrogen and oxygen using a mixture of biological components and human made technologies. The research could now be used to revolutionize the systems used for renewable energy production. A new paper, published in Nature Energy, outlines how academics at the Reisner Laboratory in Cambridge developed their platform to achieve unassisted solar-driven water-splitting.
Their method also managed to absorb more solar light than natural photosynthesis. Artificial photosynthesis has been around for decades but it has not yet been successfully used to create renewable energy because it relies on the use of catalysts, which are often expensive and toxic. This means it can't yet be used to scale up findings to an industrial level. The Cambridge research is part of the emerging field of semi-artificial photosynthesis which aims to overcome the limitations of fully artificial photosynthesis by using enzymes to create the desired reaction.

The researchers not only improved on the amount of energy produced and stored, they managed to reactivate a process in the algae that has been dormant for millennia. The researchers say, hydrogenase is an enzyme present in algae that is capable of reducing protons into hydrogen. During evolution, this process has been deactivated because it wasn't necessary for survival but we successfully managed to bypass the inactivity to achieve the reaction we wanted -- splitting water into hydrogen and oxygen. The findings will enable new innovative model systems for solar energy conversion to be developed.
  • TIET is making continuous efforts to associate with industry through its IET network to make the motto of 'Design in India' successful. In continuation to this endeavor, the founder and CEO of TIET, Prof Sham Tickoo, was invited by CII to participate as a key speaker in BPM Asia Conference – Transforming Business through Process Based Management on 9th August, 2018 at India Habitat Centre, New Delhi. He spoke about the gap between the knowledge imparted in the colleges in India and real need of industry.
