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....

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....

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....

DEALING WITH AMBIENT CONDITIONS WHEN PLACING CONCRETE TOPPINGS (Rain, heat, and cold can all have a negative impact on a topping slab.)

Toppings are subject to the same general industry recommendations for hot- and cold-weather concreting practices as any other concrete. Proper planning and execution is essential for minimizing the negative effects of weather extremes on topping placement, consolidation, finishing, curing, and strength development. When planning around the effects of ambient conditions on topping constructi....

Build. Connect. Expand in Oman

The Sultanate of Oman is considered as one of the fastest-growing countries in terms of infrastructure development. The country’s five-year plan and Vision 2040 program outline the roadmap to diversifying the economy through increased government spending on key non-oil sectors and stimulating private investments in various sectors including the infrastructure and construction industri....
