Substituting waste materials for cement in concrete helps lower the concrete industry’s carbon emissions and keeps waste materials out of landfills. However, large amounts of glass cullet in concrete will decrease the concrete’s mechanical properties. Researchers in Poland investigated reinforcing the cement–glass composite using plastic fibers.

To date, recycling of building rubble into new construction products is limited because the material does not meet strict building regulations. A new £6 million project led by Manchester Metropolitan University and partners across Europe aims to overcome this limitation using additive manufacturing because products produced this way are not subject to the same building restrictions.

Existing creep damage models for concrete assume compressive and tensile creep are identical, but recent experimental evidence suggests otherwise. Researchers from the United Kingdom and China propose a modified model that accounts for drying-induced damages and load eccentricity to more accurately model creep.

To reduce carbon emissions from cement manufacturing, emission-heavy steps of the process can be replaced with alternative techniques. Researchers from the Massachusetts Institute of Technology experimented with using electrolysis to create cement and found that in addition to reducing carbon emissions, byproducts from the process can be reused.
