Keeping concrete warm during transport between the mixing plant and construction site results in a better, cheaper and more eco-friendly product. A new type of concrete mixer truck can result in less wastage and better quality of this important building material.

Strong storms can trigger steep, breaking waves that slam into platforms and wind turbines with tremendous force. Scientists at NTNU and SINTEF are studying the behaviour of offshore structures subjected to these kinds of waves. Their goal is to increase safety at sea.
Many of the world’s dams are not used for hydropower, but a new study shows they could be easily altered to produce renewable energy. This would be the most sustainable solution for new energy production in the world, says NTNU Professor Tor Haakon Bakken.
Researchers have studied the energy consumption of 140 hotels in Norway and Sweden. The use of CO2 heat pumps could cut energy consumption in these hotels by about 60 per cent.
Is your home office in the living room, or is your whole family working at home? Here’s some good advice to make sure your indoor climate is healthy.
Moreover, researchers have succeeded in increasing its output dramatically by providing the panel with its own cooling system.
Cement manufacture accounts for as much as seven per cent of global greenhouse gas emissions. A new hybrid technology makes it easier and less expensive to capture and purify CO2 produced by the industry. And the technology can be retrofitted to existing plants.
For the first time this week, the Nature Research Group, publishers of Nature, will host an international conference in Trondheim in cooperation with NTNU, SINTEF and the Geological Survey of Norway. The theme for the conference, which runs from 11-13 September, is the sustainable use of minerals and materials.
When your airport runway is located at 72 degrees south latitude and more than 4000 kilometres from the nearest major city, it better be in tiptop shape. But in Antarctica, where most runways are made of snow or ice, holes can be a big problem.
Concrete can tolerate much more force that previously believed, which could open the door to a new kind of road structure: a floating tunnel.
Storing compressed air in sealed tunnels and mines could be a way of storing energy in the future – if an EU project in which Norway is a partner is successful.
The 11 March 2011 Tohoku-Oki earthquake was the largest and most destructive in the history of Japan. Japanese researchers — and Norwegian partners — are hard at work trying to understand just what made it so devastating.
You might think that polar bears— and the potential for attack— are the biggest danger on the Norwegian island archipelago of Svalbard. But avalanches kill far more people on Svalbard than polar bears ever have.
Combining old and new to achieve reduced energy consumption, a better living environment and architectural success. It’s definitely possible and researchers will show you how.
What happens to people’s comfort level when the heating system in a super-insulated building is simplified by installing only one radiator per floor?
The Arctic is set to be a 21st century boomtown, as summer sea ice melts away, opening the area to increased trans-Arctic shipping and oil and gas development. A new understanding of Arctic coastal erosion offers clues to how to best protect the docks and other infrastructure this development will bring.
Norway is evaluating innovative housing options for dementia sufferers. Perhaps small serviced housing projects and dementia ‘villages’ will provide a more normal life than nursing homes and institutions?
Global warming is upending virtually everything that scientists know about the Arctic ice cap. During the first half of 2015, a multinational team of researchers froze the RV Lance into the Arctic ice to learn more about how this ice has changed. NTNU researchers were among the scientists seeking to learn more about this changing environment.
Norway’s wealth and prosperity over the last four decades has been built on oil, but Jeremy Rifkin, a futurist and social and economic thinker, says it’s time for the country to change. The Third Industrial Revolution is coming, and Norway needs to abandon fossil fuels and move towards a greener future that relies on renewable energy, shared transport and ultra-efficient housing.
The production of oil and gas at temperatures between 40 and 60 degrees below zero means that researchers must advance the development of materials that can withstand these harsh conditions.
NTH, Norway’s first technical university and one of the main predecessors to NTNU, SINTEF and MARINTEK, opened in Trondheim in 1910. Just three years later its scientists began to think very big – 170 metres big.
