Bendable Concrete – A Stronger, More Durable Concrete

Sarah McGuire August 17, 2016

Increased Tensile Strength with Flexible Concrete Typical concrete is characterised by its heavy, brittle qualities which lends itself to breakage under tension. To combat this, Nanyang Technological University scientists from the NTU-JTC Industrial Infrastructure Innovation Centre (13C) have invented a new type of concrete called the ConFlexPave. What makes this innovation superior is that it is bendable and yet stronger and longer lasting than regular concrete.

Real-time insights, up to 1,000 ft away with SmartRock® Long Range Request a Quote With utilization of this new revolutionary concrete comes a drastic reduction in the time required for road works and new pavements as it allows for the creation of slim precast pavement slabs for speedy installation. As it is more sustainable than regular concrete, it further requires less maintenance….

High Modulus of Elasticity for High Rise Structures

Sarah McGuire August 5, 2016

Modulus of elasticity (MOE) in concrete refers to the measurement of resistance a concrete structure has to deform or sway. That is, it measures the stiffness of the concrete. This measurement is used for high rise buildings, bridge piers, and other structural applications where the stiffness of the concrete is of essential importance.

Modifying the Microstructure of Concrete to Decrease Emissions

Sarah McGuire July 25, 2016

An MIT-led team has defined the nanoscale forces that control how particles pack together during the development of cement “paste,” the material that holds together concrete and causes that ubiquitous construction material to be a major source of greenhouse gas emissions. By monitoring those forces, the researchers will now be able to adjust the microstructure of the hardened cement paste, reducing pores and other sources of weakness to make concrete stronger, stiffer, more fracture-resistant, and longer-lasting. Results from the researchers’ simulations explain experimental measurements that have puzzled observers for decades, and they may guide the way to other improvements, such as adding polymers to fill the pores and recycling waste concrete into a binder material, reducing the need to make new cement.

Seattle Concrete Tunnel Project is Beginning to Take Shape

Sarah McGuire July 14, 2016

Portions of the vast Highway 99 tunnel are starting to look like the double-decker thoroughfare that former Gov. Chris Gregoire promised seven years ago. Bertha’s recent progress along the Seattle waterfront — some 1,500 feet since diving below the Alaskan Way Viaduct on April 29 — has allowed crews to pour concrete walls and foundations for road decks. The giant tunnel-boring machine is currently stopped for inspection and replacement of some of its 75-pound steel cutting teeth, below Spring Street just west of First Avenue.
