Lobster shell patterns make concrete stronger: Australian researcher
Inspired by the natural, twisting patterns of a lobster shell, Australian researchers say they have found a way, using 3D printing technology, to improve the strength of concrete for use in complex architecture.
Concrete jungle threatens mangroves on Pakistan island
A short boat ride from the shores of Karachi, mangrove trees sprout along the quiet inlets of an uninhabited island that environmentalists say provides vital coastal protection to Pakistan's largest city.
Researchers use 3D printer to make stronger, greener concrete
Researchers at University of California, Berkeley, have developed a new way to reinforce concrete with a polymer lattice, an advance that could rival other polymer-based enhancements and improve concrete’s ductility while reducing the material’s carbon emissions.
Bio-inspired ‘antifreeze’ formula provides more durable concrete
Concrete is one of the most abundant and durable building materials used in modern-day infrastructures, but it has a weakness — ice — which can cause it to crumble and spall. Now, inspired by organisms that survive in sub-zero environments, researchers in Colorado, the US, are introducing polymer molecules with anti-freezing abilities into concrete.
Hunger for concrete eats away at mountains
Soon, Jamal's voice will no longer ring out over the mountain slopes he's roamed for years with his herd in northern Cyprus.
The battle to curb our appetite for concrete
We extract billions of tons of sand and gravel each year to make concrete for the building industry, and this is having an increasing environmental impact as beaches and river beds are stripped, warn campaigners.
SCRIM: An innovative method for 3D concrete printing
Researchers at the Center for Information Technology and Architecture (CITA) of the Royal Danish Academy of Fine Arts and at the Danish Technological Institute have developed a new hybrid construction concept called ‘Sparse Concrete Reinforcement In Meshworks’ (SCRIM).
Seawater makes ancient Roman concrete stronger
Most people think of sea water as corrosive and erosive. But centuries of exposure to seawater has made ancient Roman concrete stronger. Now, researchers know how.
Technique developed for turning Mars or Moon rocks into concrete
Civil engineers at Stanford University have worked with colleagues at NASA to develop a form of concrete that humans could produce on Mars or Moon.
Researchers hope to make concrete tougher
Calcium silicate hydrate, or C-S-H, accounts for the strength of cement and cement-based materials. It is the component of cement paste that holds concrete together.
US must take concrete, objective steps on JCPOA: Iran FM
Iranian Foreign Minister Mohammad Javad Zarif says the US should take more objective steps to guarantee international banking transactions with Iran under last year’s nuclear agreement between Tehran and the P5+1 group of countries.
Iranians improve concrete's frost resistance
Isfahan University of Technology researchers have improved frost resistance of normal concrete, using nano-silica and nano-alumina.
Iran builds reinforced concrete with nanomaterials
Iranian researchers at the Islamic Azad University have designed reinforced concrete using nanotechnology.
