We Know Why Ancient Roman Concrete Lasts Thousands of Years (sciencealert.com)
The ancient Romans were masters of building and engineering, perhaps most famously represented by the aqueducts. And those still functional marvels rely on a unique construction material: pozzolanic concrete, a spectacularly durable concrete that gave Roman structures their incredible strength.

50 Things I've Learned Writing Construction Physics (construction-physics.com)
I’ve been writing Construction Physics since September of 2020. Over the past four and a half years I’ve written 186 essays, totalling around 600,000 words. The newsletter was originally focused on understanding the problems of construction productivity (though it’s never been entirely about that), but I have branched out to write more about a variety of topics, including energy, transportation, and scientific and technological progress.
Spray-on concrete innovation could transform bridge repairs (techxplore.com)
More than 40,000 bridges in the United States are deemed structurally deficient, and as many as 221,000 are deemed in need of repair, according to the American Road & Transportation Builders Association. Florida International University (FIU) researchers have developed a system that could play a key role in restoring them.

Why Hong Kong uses bamboo scaffolding, and meet the spider-men who climb it (scmp.com)
Hong Kong is one of the last places in the world where bamboo is still widely used for scaffolding in construction. It’s flexible, strong and cheaper than steel and aluminium — metal alternatives that are now more commonly used in mainland China and elsewhere in Asia.
Innovative ways to float skyscraper-sized wind turbines (mena-forum.com)
Record-tall Wind Turbine Towers with 3D-printed Concrete Bases were in the news a few years back. Today, here are six innovative ways to float skyscraper-sized wind turbines. These enormous turbines can reach up to 240m tall—about the size of a skyscraper. Since they are so tall, strong winds far above the sea surface tend to cause the turbine to tilt, so platform designs focus on minimising this tilt while still being cost-competitive with other forms of energy.
The engineering behind the San Antonio River Walk (practical.engineering)
I am on location in downtown San Antonio, Texas, where crews have just finished setting up this massive 650-ton crane. The counterweights are on. The outriggers are down. And the jib, an extension for the crane's telescoping boom, is being rigged up. This is the famous San Antonio River Walk, a city park below street level that winds around the downtown district.
