The construction industry is constantly growing and changing. New projects, new techniques and new building materials. The market demands well designed buildings that offer more than just a space to live in or work, they need to be 'smart', 'sustainable' and built for the future.
As part of this growing trend new construction materials and techniques are being developed. foundU is always interested in innovation and had a look at some of the latest.
3-D Concrete Printing
3-D printers have been around for a while now, you can even buy one at Officeworks. 3-D printers mainly print small items in plastic, not super-valuable for the construction industry. But what if you could print in concrete?
Researchers from Loughborough University in England, have developed a 3-D concrete printer that can produce complex shapes. So far they have built a 1 tonne bench and a 2-metre curved panel. The value of the machine is that it can come on site and print exact pieces for a construction job.
Solar Windows
Solar power was first discovered in 1839 with the solar cell being invented over a 100 years later. Today, it is not uncommon to see buildings or street lights powered by energy from the Sun. The main limitation of solar power is the cost, it is still easier to connect a building to mains energy. It also makes a build more complex having to install solar panels on a building. Instead of big, cumbersome solar panels, some companies are now embedding solar cells in windows.
One company gets normal glass and sprays it with tiny functional organic solar cells. These cells are quarter the size of grain of rice and have the capacity to power an entire building. Simple and easy solar power with no extra space.
Self-Healing Concrete
Concrete cracks, pure and simple. A concrete crack needs to repaired and each year millions of dollars and thousands of hours are spent fixing concrete cracks. But what if concrete healed itself? The moment a crack started forming the concrete sealed the damage using the power of the Sun?
It does in fact exist, concrete that is covered in millions of tiny microcapsules full of a concrete repairing solution. When a crack starts to form the capsules break and begin filling the whole with the solution. The solution is exposed to sunlight and sets, fixing the damage.
Metal Foam
There is foam, then there is metal foam. Metal foam is foam like in appearance but is actually made from solid metal. The applications are endless but there are potential uses in the construction industry.
It is super-light and some metal foam can even float on water. It has been suggested that in the future it could be used to build floating cities. It is great insulator of sound, vibration and heat. Possible uses include building insulation and vehicle production.
