America’s First Vertical Evacuation Shelter
Seismologists are predicting a one-in-three probability of a catastrophic earthquake with a very high likelihood for a subsequent tsunami to hit the coast of the Pacific Northwest within the next 50 years. With the majority of the coast wholly unprepared, a few places are taking steps to prepare…
Laser Scanning: New Fire Damage Detection in Concrete
Though concrete is known to be a material which has high fire-resistance, its physical, chemical and mechanical properties do endure severe changes when subjected to high temperatures – particularly with temperatures over 300 degrees Celsius. Fire is actually one of the most serious potential risks to concrete structures…
Have no Fear – EMP-Proof Concrete is Here
Have you ever had the fear that we are under the threat of an EMP attack that will knock out all electronics – spiralling the world into apocalyptic chaos? Well, thanks to the work of University of Nebraska engineers Christopher Tuan and Lim Nguyen, such worries of our…
Smog-Eating Concrete to Battle Air-borne Pollution
Around the globe one of the biggest collective concerns is that of pollution. With the heat on them due to the increased amounts of CO2 entering the air from production facilities and energy sourcing, engineers are now looking to come up with creative solutions to battle it. Explore…
According to ACI 347-04, “Guide to Formwork for Concrete”, bug holes are surface voids in concrete defined as small regular or irregular cavities that usually do not exceed 15 mm in diameter. They are the result of the entrapment of air bubbles in the surface of formed concrete…
The Use of Pozzolans in place of Fly-Ash in Concrete Mix Design
Fly-ash, a component found in burning coal, is a common aggregate added to the composition of concrete as a means to increase strength. But because coal is being used less in the generation of electricity in particular states, including California, the issue of fly ash shortages needs to…
Replacing BT-Roads by Concrete to Improve Durability
Bitumen is a black, oily and viscous material that is a naturally occurring organic by-product of decomposed organic materials. It is a common binder that is mixed with and glued together aggregates to make asphalt and its primary use is found in road construction. However, due to the…
