Translucent wood as construction material
We now have translucent wood that can be used to develop windows and solar panels. It is created by first, removing the lining in the wood veneer and then through nanoscale tailoring. The resulting effect creates translucent wood that has various application in the construction industry.
As a very cheap resource, it can benefit projects by reducing cost of resource.
The innovation took place at Stockholm’s KTH Royal Institute of Technology. Lars Berglund, a professor at KTH claims that transparent wood is a low cost, readily available and renewable resource.
2. Cooling system in bricks
Through the combination of clay and hydrogel, students at the Institute of Advanced Architecture of Catalonia have created a new material that has a cooling effect on building interiors.
Hydroceramics have the ability to reduce indoor temperature by up to 6 degrees celsius.
Its cooling effect comes from the presence of hydrogel in its structure which absorbs water, up to 500 times its weight. The absorbed water is released to reduce the temperature during hot days.
Incorporating an innovative cooling system in the current building structure has made Hydroceramics into one of the coolest building materials to revolutionize construction. More progress in this direction, may make household air conditioners obsolete.
Cigarette butts to make bricks
On a yearly basis, 6 million cigarettes are manufactured and they produce 1.2 million tonnes of cigarette butt waste. The impact on the environment is tremendous. Elements such as arsenic, chromium, nickel and cadmium enter the soil and harm nature.
In order to reduce the impact of cigarette butts on the environment, researchers at RMIT developed lighter and more energy efficient bricks made of cigarette butts. In short, innovatively utilizing waste in a much more eco-friendly manner.

Dr. Abbas Mohajerani, the leading researcher of the project, along with his team discovered that by infusing even 1% of cigarette waste in fired-clay bricks they can have great results in removing pollution from our environment.
Not only does this research help with reducing waste, but the resulting brick is also lighter and requires less energy in manufacturing it.
We now have Martian concrete
It’s finally done! We have concrete that can be used to build structures in Mars now. The researching team at the Northwestern University, has created concrete that can be made with the materials available on Mars.
The new concrete also doesn’t require water as an ingredient to be formed. With the scarcity of water as a source, this crucial benefit can make this innovation truly beneficial for the development of structures in Mars.
In order to make the martian concrete, sulphur is heated at 240° celsius which melts it into a liquid. The martian soil then acts as an aggregate and once it cools down we get Martian concrete! According to the researching team, the ratio of martian soil and sulphur needs to be 1:1.
Light generating cement
Dr. José Carlos Rubio Ávalos from UMSNH of Morelia, has created cement that has the ability to absorb and irradiate light. With this new light generating cement the potential uses and application of it can be huge.
The construction industry is evolving and one of the main trends is the move towards a more resource and energy efficient way of creating structures. Therefore, the implications of cement acting as a ‘light bulb’ are very broad. We can use them in swimming pools, parking lots, road safety signs and much much more.
The science behind it: Through the process of polycondensation of raw materials such as river sand, industrial waste, silica, water and alkali. The process is done at room temperature which is why the energy usage is low.
In short, we now have smart cement!
The CABKOMA strand rod
The Komatsu Seiten Fabric Laboratory, based in Japan has created a new material called the CABKOMA Strand Rod. It is a thermoplastic carbon fiber composite.
The strand is the lightest seismic reinforcement and is very aesthetically pleasing.
A single strand of CABKOMA Strand Rod of 160 meter length weighs only 12 kg which is 5 times lighter compared to a metal rod.
The value of this material can be seen at the headquarters of Komatsu Seiten. The strands have enforced the entire structure.
Biologically produced furniture
So far there are two pieces of furniture created through this material – a chaise lounge and a small chair for kids. The furniture is made by a material called Mycoform, which is made by combining wood chips, gypsum, oat bran together with a fungus called Ganoderma lucidum. This fungus is added as it has the ability to disintegrate waste products and leave a strong structural material.

This combined effect creates a plastic furniture that through time combusts. According to Terreform One, this process is low energy, pollution free and requires low technology for the creation.
Over the water of Italy’s lake Iseo, you can see another great innovation in the construction industry – Floating piers by artists, Christo and Jean-Claude.
The floating dock system is composed of 220,000 polyethylene cubes of high density. It is a three kilometer long walkway with 100,000 square meters of yellow cloth wrapped around it. The cubes undulate along the waves of the lake.
The beautiful master piece extends from pedestrian streets of Sulzano and connects the islands of San Paolo and Monte Isola.
Pollution absorbing bricks
We now have pollution vacuums in bricks! Developed by assistant professor Carmen Trudell at Cal Poly, college of architecture and environmental design, the Breathe Brick sucks in pollutants in the air and releases filtered air.
The innovative material is designed to be part of a building’s standard ventilation system. It has a two layer facade system, with the specialist bricks on the outside and standard insulation on the inside.

In the center is a cyclone filtration system that separates out the heavy air particles from the air and collects them in a removable hopper. Its design is very similar to a vacuum. The design of breathe bricks can be configured in a wall with window and a cooling system as well. In short, it is a technology that can be easily applied to the current construction processes.
By performing wind tunnel tests, it was proven that the system can filter 30% fine particle pollutants and 100% coarse particles such as dusts.
Self healing concrete
Dutch civil engineer, Dr. Schlangen at Delft University has created a self healing concrete. In his presentation, he demonstrated the effectiveness of the material by breaking it in two, putting the pieces together, and heating the concrete in a microwave oven. Once the melted material cools down, it joins together.
Of course with this method, the concrete needs heat. If the material is used to create roads, how will they be heated up?? To solve that problem, Dr. Schlagen and his team created a special vehicle that passes induction coils on the road.
Dr. Schlagen estimates that the machine will be used to run on the concrete every four years and that this innovative technology could save the country $90 million annually.
The future looks promising!
We have just seen a glimpse of what has been achieved in the construction industry so far. There is so much more out there for us to see and the journey has just begun. We hope that science and technology will keep progressing and accelerating the pace of change that is coming our way!
