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 »

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 »

The US Army is 3D Printing Concrete Structures

Additive manufacturing processes—also known as 3D printing—are being used to make everything from medical devices to engine components, and now the U.S. Army is even using employing a similar technique to build concrete structures. The U.S. Army Corps of Engineers has devised a system that allows them to create lightweight concrete structures quickly with a… Read more »

Graphene Could Make Concrete Stronger, More Eco Friendly

Recent advances in nanoengineering have allowed scientists at the University of Exeter to develop an innovative new technique that incorporates graphene into conventional concrete production. The graphene-infused concrete is reportedly twice as strong and four times more water resistant than traditional concrete mixes. It also reduces the amount of materials needed to make concrete by… Read more »
