Cementless concrete made from industrial waste could reduce global carbon emissions
Concrete made from fly ash and other industrial waste products could lower the carbon emissions associated with large construction projects, according to scientists at Kaunas University of Technology (KTU) in Lithuania.
The final product is as strong as traditional concrete, is more resilient to the damaging effects of acid and is more stable in cases of exposure to extreme heat and cold.
Current estimates find that the global cement industry is responsible for 7 per cent of yearly carbon dioxide emissions into the atmosphere.
To produce one metric ton of Portland cement – a basic ingredient of concrete and the most commonly used type of cement around the world – up to one ton of carbon dioxide is released.
This is a remarkable discovery and could seriously benefit our eco-system, click here to read the full article.
Zaha Hadid Architects and ETH Zurich debut concrete pavilion with 3D-knitted formwork
A double-curved concrete shelled pavilion, constructed using a 3D-knitted formwork developed by Zaha Hadid Architects and ETH Zurich, has gone on display in Mexico City.
The pavilion named KnitCandela, was built using KnitCrete – a new 3D-knitted textile technology for creating curving concrete structures, without the need for expensive and time-consuming moulds.

Colored concrete and perforated fins keep this downtown school cool
Completed in November 2017, the Perkins Eastman–designed School of Nursing and Science Building occupies a former parking lot in downtown Camden, establishing a new institutional heart for Rutgers University in the slowly reviving city. The design inhabits a formidable full-block mass, reaching a height of four stories with a multidimensional facade of high-performance concrete and glass curtainwall shaded by perforated panels.
Similar to other urban centers across the Rust Belt, Camden has undergone a significant period of economic stagnation and demographic decline since the mid-20th century. However, the continued expansion of healthcare institutions, such as the Nursing and Science Building, is fundamentally reshaping the city’s character.

Shaldon Bridge support pier made of wood not concrete
A defective bridge has had a weight restriction placed on it after safety concerns were raised by engineers.
An inspection by Devon County Council revealed that one of the supports of Shaldon Bridge was actually made of deteriorating timber, not concrete.
The council said the other four supports will now be inspected to determine their quality.
Vehicles that weigh more than three tonnes will not be allowed to cross for at least three months.
The original drawings for the 87-year-old bridge – which links Shaldon with Teignmouth – showed the five support piers constructed from steel and concrete.
