A Rowan University team of engineers has developed a new way to measure how 3D printed concrete deforms during printing and curing, revealing how lower layers respond to the weight and pressure of newly deposited material.
Every summer, fires once again highlight the importance of solutions that can help minimize their consequences.
A pioneering ultra-low carbon brick made from near 100% recycled construction waste has been used to create the striking colorful façade of one of London's most anticipated new cultural buildings.
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.
