Did you know that modern concrete bridges require maintenance about once every five years, and major rehabilitation every 20 years? That’s true now, but a new type of rebar could change that in the future. A team of engineers at Deakin University in Victoria, Australia has developed an experimental polymer rebar to reinforce concrete and… Read more »

Hawaii DOT Tests New Carbon-Injected Concrete Mix
In an effort to reduce the carbon footprint of road construction, the Hawaii Department of Transportation (HDOT) is testing a new carbon-injected concrete mix. To test the mix, HDOT will pour about 4000 cubic feet of the carbon-injected concrete mix next to the same amount of standard concrete mix. The test will take place on… Read more »
MIT Designers Create Huge Concrete Blocks That Can Be Assembled by Hand
Visit just about any construction site today and you’ll see cranes hoisting large slabs of concrete into place. However, cranes haven’t always been around, and for thousands of years human beings moved large stones by hand. Matter Design, a Boston-based company directed by MIT professor Brandon Clifford, recently collaborated with the multinational building materials company… Read more »
How to Keep Weeds From Growing in a Concrete Paver Patio
Are unsightly weeds taking a toll on the appearance of your concrete paver patio? These weeds might be awfully stubborn, but there are steps you can take to prevent unwanted growth from sprouting in the joints of your paver patio. This way, your patio will always look as good as the day it was first… Read more »
Old Tires Could Help Prevent Fire Spalling in Concrete Structures
When a concrete structure or paved surface is involved in a fire, it won’t burn. It may, however, “spall.” When this happens, the outer layers of concrete will break apart violently and leave the structure unstable. In some cases, an entire structure may collapse to the ground as a result of intense fire spalling. The… Read more »
Texas Company Receives Permit to Build 3D-Printed Concrete Homes
Over the course of the past few years, there has been a lot of buzz surrounding the idea of 3D-printing homes and other structures. 3D-printed homes have the potential to be affordable, durable and sustainable—a combination that is appealing both to home builders and prospective homeowners. But until recently, most companies pursing 3D-printed construction have… Read more »
Concrete Overlays Are Extending the Life of America’s Roads
Does it seem like road crews are resurfacing the highways in your area with fresh asphalt practically every year? This is due to the fact that asphalt roads, for all their virtues, have fairly limited lifespans, particularly in regions that experience harsh winter weather. Thanks to recent innovations in the paving industry, however, some contractors… Read more »
Scientists are Working to Develop Carbon Neutral Concrete
Concrete might form the bedrock of modern urban construction, but its impact on the environment is raising concerns among climate researchers. Recent estimates suggest that Portland cement, the essential binding ingredient in concrete, accounts for roughly seven percent of global carbon emissions. That could change soon, however, thanks to a multinational effort to drastically reduce… Read more »
In India, Waste Plastic Could Begin Replacing Sand in Concrete
India’s urban populations are growing at an unprecedented rate, and construction crews are having trouble keeping up with the demand for structural concrete due to a nationwide sand shortage. Meanwhile, the country’s lack of recycling infrastructure is allowing thousands of tons of waste plastic to pile up in city streets as well. But thanks to… Read more »
Engineer Develops New Sealant That Could Prevent Concrete Cracks
The nation’s concrete roadways receive a whole lot of wear and tear, particularly in regions that experience extreme changes in temperature during the summer and winter. These temperature fluctuations can cause paved concrete surfaces to expand and contract, resulting in cracks that require seasonal repairs and replacement. Thanks to the efforts of a mechanical engineering… Read more »
