Video: Designing concrete trumpets using 3D printing

By Lisa McDonald / May 12, 2021

Wind instruments can be made from an array of materials because the sound depends mainly on how the air is shaped rather than the instrument’s body. Learn how a German mechanical engineer used 3D printing to design a trumpet out of concrete.

Reinforcing waste-based concrete: Plastic fibers improve mechanical properties of cement–glass composite

By Lisa McDonald / February 16, 2021

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.

Repurpose waste concrete through additive manufacturing

By Lisa McDonald / December 1, 2020

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.

Weak concrete, heavy trucks—understanding reasons for sewer line failure

By Lisa McDonald / August 7, 2020

Numerous factors contribute to failure of concrete sewer pipes. Researchers at The Ohio State University used a surrogate model to identify which factors play the largest role in these failures, isolating critical areas for improvement.

A creeping suspicion—modified concrete creep model considers drying-induced damage

By Lisa McDonald / February 21, 2020

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.

Reduce carbon emissions from cement production—and make other useful products in the process

By Lisa McDonald / November 5, 2019

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.
