There is a continuous increase in population which is leading to more and more people shifting to cities. The demand created leads to urbanization increasing and hence, the demand for construction. According to the study, ‘Construction Materials Global Group Of Eight (G8) Industry Guide 2013-2022’, the G8 nations are hubs of modern construction projects.
The US among the G8 nations is a prime example of new construction projects that are incorporating innovative materials. The project of Hudson Yards in Manhattan is turning 28 acres of land into a skyscraper project base. This project will be the largest private real estate development in the nation’s history and is now raising awareness about smart building materials. At Rice University’s Multiscale Materials Laboratory, Texas, researchers have discovered an unknown principle of calcium-silicate-hydrate (CSH) behavior. The researchers believe that by controlling the kinetics of these particles, they can create what they refer to as ‘programmable cement’. They also believe that by shaping its microstructure they can compel these particles to self-assemble for much greater packing density than conventional cement structures.
Apart from the US, Japan too is a G8 nation that is using its extensive technological know-how in this industry. Self-compacting concrete (SCC) was initially developed in Japan as a Quality Assurance measure but is now being used globally for concrete structures. However, Japan’s progress is still continuing as it has been working on plans to break engineering grounds with new and eco-friendly materials. A Japanese company has recently revealed plans to build a 350 meter high timber tower. Sumitomo Forestry’s vision for its tower, if realized will be an innovative achievement for the field. The structure would be made of hybrid materials but would majorly consist of timber.
Canada however, has launched its own string of developments. Researchers at the University of British Columbia have discovered additives to help concrete withstand 9.0 earthquakes. The researchers have discovered a spray-on concrete reinforcement that greatly improves concrete’s resistance to earthquakes up to a magnitude of 9.0 Concrete walls are sprayed with the reinforcement which is made up of polymer based fibers, fly ash and other industrial additives. The retrofit reinforcement allows the concrete to adjust and slightly bend with the movements of the earthquake, making it much more ductile. The product is being called Eco-Friendly Ductile Cementitious Composite or EDCC. This product is proving to be pretty innovative as it is opposed to traditional reinforcements that have always been added prior to the concrete placement or within the concrete mixture. This product is proving to be a time and cost saver as well.
From modern material to natural reinforced materials, the current construction materials’ industry is witnessing a number of interesting developments. Most of these are being augmented by G8 nations like US, Japan and Canada. The G8 countries consist of some of the most advanced nations in the world and these nations are combining innovation and technology to make landmark impacts in various fields including the construction sector.
