Making stronger concrete with 'sewage-enhanced' steel slag
Researchers have shown how a by-product of steel making can be used to both treat wastewater and make stronger concrete, in a zero-waste approach to help advance the circular economy. Produced during the separation of molten steel from impurities, steel slag is often used as a substitute aggregate material for making concrete. Steel slag can also be used to absorb contaminants like phos.....jpg)

Bricks printed from recycled plastic smash clay for U-values
Researchers at De Montfort University in Leicester have created a super-insulating house brick out of domestic plastic waste. A team led by Dr Karthikeyan Kandan, senior lecturer in mechanical engineering at De Montfort University (DMU), made the brick using 3D printing and lattice architecture technologies, criss-crossing strips of recycled plastic to form a weave. Lab tests show it pr....
Cat brings out new backhoe loader series
The new backhoe loader line consists of the Cat 428, 432, 434 and the 444 models, replacing the 428F2, 432F2, 434F2 and the 444F2 machines respectively. The new machines offer similar model platforms throughout the line, with similar components and operating layouts. The new models are powered by the Cat C3.6 engine, which meets EU Stage V emission standards by means....
New Glass Products from AGC Unite Clarity and Performance
Low-iron glass and low-e coatings combine to bring architects and designers another tool in the effort to balance appearance, daylight and energy efficiency. Interior spaces which prioritize environmental and human wellbeing focus on maximizing daylighting. The benefits to this approach include improved concentration and focus, while reducing the need for arti....
Concrete recycling creates bendy new construction material
A procedure for recycling concrete has been developed which combines the building material with discarded wood to form a new material with a bending strength superior to that of the original concrete. Researchers at the Institute of Industrial Science, University of Tokyo, said they discovered the correct proportion of inputs to yield the new material. The material is likely to be biode....
