Get to the point
Years ago, I worked on the development of high-performance concrete for an offshore oil platform in Alaska. We needed to conduct abrasion testing at below-freezing temperatures, so we wanted to […]

Material Change report aids in responsible sourcing
Responsible sourcing is the human-rights aspect of supply chains. The idea is that it’s not enough to follow ethical practices within your own business. You also need to ensure that […]
Passive radiative cooling saves energy
As we’ve discussed previously, keeping spaces cool in summer takes a lot more energy than heating them in winter. And some things—such as food and vaccines—must stay cold to remain […]
What I’d like to see more of in specifications
At Beton we review project specifications for various reasons. Sometimes it’s to develop concrete mixture proportions that will help a contractor meet the requirements. Sometimes it’s to come up with […]
A test for spotting fraudulent statistics
As countries report their death tolls due to COVID-19, some appear to be providing fraudulent statistics. Dmitry Kobak has examined them using the Poisson distribution. It’s a useful way to […]
Julia Morgan, architect and engineer
Before Julia Morgan became an architect, only men practiced architecture. First she studied civil engineering at the University of California at Berkeley, graduating in 1894—the only woman in her class. […]
Mostly good news about water quality
Can we improve the water quality of our lakes and rivers? It turns out that there are things we can do, and they’re working. Reviving dead zones in the Thames […]
Technology makes vaccines available in Africa
As the third year of the pandemic begins, we know it won’t be over until people everywhere receive the vaccine—and maybe not even then. But it’s not just a matter […]
Managing the water footprint in construction
We’ve discussed the carbon footprint of concrete previously. However, carbon dioxide and other greenhouse gases aren’t the only environmental effects of construction. Making the best use of scarce resources is […]
Deep water cooling
Keeping interior spaces cool in summer is much less energy- and carbon efficient than heating them in winter. For this reason, most of the CALGreen provisions for making buildings energy […]
