A global energy-economy model found that parallel AI adoption across fossil fuel, renewable, and fuel-neutral pathways could increase annual CO2 emissions by 0.5–1.8 gigatonnes. Renewable productivity gains would need to exceed fossil fuel gains by approximately four to five times to reach emissions breakeven.
Researchers developed a cement composite containing 0.13 wt% polymer that migrates toward cracks under humid conditions and forms reversible bonds with fractured surfaces. The material recovered up to 62% of its compressive strength and 59% of its direct tensile strength, with compressive recovery continuing across six damage-healing cycles.
Using cargo recovered from one of Australia’s most infamous shipwrecks, new Curtin University-led research has revealed how surprisingly sophisticated global supply chains helped source and transport construction materials in the 17th century.
Long-term carbonate mineralization helped preserve a 2nd-century Roman concrete sample from Hadrian’s Villa by forming calcite cements that filled pores, fractures, and microcracks. The study shows that calcite, alongside smaller amounts of C-A-S-H from volcanic aggregate reactions, contributed to the material’s millennial durability.
A WREC 2026 conference paper proposes a structured database to identify and assess critical mineral tailings for low-carbon concrete production using geopolymer cement. By linking tailings chemistry, mineralogy, location, logistics, and performance data, the framework could help turn mining residues into circular construction resources.
Researchers developed an electrochemical process that converts limestone and silica into calcium silicate hydrate at 60 °C and 1 bar, enabling belite-rich cement clinker to form at 650 °C rather than the conventional 1200 °C. Using waste cement as the calcium feedstock, the modeled process could reduce production-stage CO2 emissions to 20 kg per ton of cement, a 98% reduction compared with conventional cement production.
A new study links bacterial viability to carbonate production in MICP, offering insights for the use of aged bacteria in sustainable soil improvement techniques.
Strongwell (USA), the world’s leading pultruder of fiber reinforced polymer (FRP) composites, announced today that its STRONGDEK® architectural decking system has been recognized with a 2025 Product Innovation Award (PIA) by Architectural Products magazine.
BEClimate, a digital-first climate infrastructure platform for the built environment, has launched the world's first fully integrated climate ecosystem tailored to decarbonizing buildings and infrastructure.
The new study analyzes tensile characteristics of fiber-reinforced concrete, focusing on how different fibers and cements affect cracking and fatigue resistance.
