Built environment is one of world’s largest storehouses of carbon

Concrete buildings, pavements and structures are silently absorbing carbon dioxide (CO2) from the air, making the built environment one of the world’s largest storehouse of carbon. »

Smart Solution for Hot Weather Concreting

Smart Solution for Hot Weather Concreting

The drier and longer days are a boon for the construction industry during the summer months, but building concrete structures in hot, and especially dry weather comes with unique challenges such as slump loss, rapid set times and excessive surface moisture evaporation. The wind is also an issue in this environment as it exacerbates the accelerated evaporation process. One or combination of the abo... »

Rust-proof reinforcement promises maintenance-free concrete

Rust-proof reinforcement promises maintenance-free concrete

A team of engineers at Australia’s Deakin University has developed a form of concrete reinforcement that may dramatically reduce the need to maintain structures such as bridges. The academics, led by Mahbube Subhani and Kazem Ghabraie, lecturers in civil engineering, have developed a rebar that uses carbon and plastic rather than steel, and will shortly test it on a pedestrian bridge near Deakin’s... »

Greening the concrete jungle

Greening the concrete jungle

The production of steel, cement and aluminium collectively accounts for about 15% of global greenhouse gas emissions and demand for the industrial materials is on the rise. A handful of pilots are underway to develop zero or nearly-zero carbon versions of these carbon-heavy materials, but the pace of change is hampered by a dearth of investment. Here is a look at some innovative pilots across the ... »
