High-performance prestressed concrete could revolutionise construction

New research into ultra-high performance concrete (UHPC) could transform the way buildings, bridges and other high-stress projects are constructed. UHPC, like normal concrete, contains cement, sand and chemical additives, but is made with different proportions that produce a denser-packed concrete that requires no steel reinforcements. The Precast/Prestressed Concrete Institute (PCI) is supporting research into new […]

Tests investigate behaviour of concrete flooring in fires

Researchers in the USA from the National Institute of Standards and Technology (NIST) recently built steel beam-supported concrete flooring structures and set blazes on them to collect data on how fire affects concrete flooring. The researchers spent months constructing various structures with concrete flooring supported by steel beams, a system commonly found in high office […]

Facebook makes use of unique concrete flooring

Facebook Reality Labs in Pittsburgh USA needed specially constructed concrete floor rooms for a new virtual reality (VR) system. The rooms where Facebook technicians create virtual avatars are black with large spheres that contain hundreds of tiny cameras used to record movements and voices of the Pittsburgh volunteers, which are made into realistic VR avatars.

Concrete strength predictions streamline workflow at London City Airport

12th February 2020 by Sean Couldwell Concrete 0 Comments

A new concrete deck at London City Airport has been laid more precisely and in good time, thanks to concrete prediction technology. Concrete contractor Converge placed sensors in freshly poured concrete which sent temperature data to a Cloud-based system, to inform engineers when the concrete is at the correct temperature for maximum strength. After analysing […]

New concrete made from waste resists military attacks

Engineers have developed a new type of concrete made up of 40% waste tinder, rice husk and sand. This concrete is economical to produce, and high impact and crackle resistant. The new concrete has been developed at the Military Studies Center at Far Eastern Federal University (MSC FEFU). It is intended for use in military […]

Is concrete the answer to flood-proof buildings?

Architects and builders are developing ways to protect homes and commercial buildings from floods, including using concrete flooring. The UK Climate Projections, published in 2018, warned that in the next few years, Britain is likely to experience higher summer temperatures, the sea levels will rise, and there will be more extreme weather, including flash floods. […]

Researchers develop salt-resistant concrete

Researchers believe they may have found a way to make concrete flooring more resistant to damage from salty water. In icy weather, tons of salt (sodium chloride) is spread on concrete flooring, roads and walkways to prevent people and vehicles from slipping on ice. Most of the salt is washed away after the cold spell, […]

Biggest ever UK concrete pour completed

A whopping 9,000 cubic metres of concrete was poured and reinforced with 5,000 tonnes of steel at the new Hinkley Point C nuclear electricity generating plant. This breaks a previous UK record set during the construction of London’s Shard skyscraper. The Hinkley Point C plant is the UK’s biggest engineering project. Expected to be completed […]
