Reversible Concrete Allows for Easy Removal

Yes, you read the title correctly – reversible concrete! It seems like an oxymoron – concrete is known for its stability and strength, and its permanence. Well, not anymore! Last October at the Chicago Architecture Biennial, Self-Assembly Lab at MIT and Gramazio Kohler Research of ETH Zurich showed off a process that might finally one-up […]

Scientists Develop Non-Eroding Surface Using Scorpion for Study

For those who have watched concrete or painted surfaces erode over the course of time from exposure to sand and weather, a new material may be ready for developmental testing – based on the desert scorpion, who has lived its entire life in the blowing sands of the desert and moves on from year to year, no worse for wear.

Green Cement: Near Reality Or Just A Dream?

Cement is everywhere. The foundations of our buildings, the driveways that lead beyond suburban garage doors, the walls of our schools, and the mortar joints between every brick we lay contain a binding substance we call Portland cement. Cement is the binding agent used to hold together the tough aggregate (rocky gravel) in the concrete […]

Pervious Pavement – Rescuing a Reservoir Near You

For some reason, watersheds seem to be popular places to put down pavement. Housing developments, grocery stores, and shopping malls require places to drive and places to park, which means those places end up getting paved. Where water used to infiltrate into the soil, trickle down through natural water-filtering aquifers and rejoin the reservoirs that serve our thirsty civilization, now rain falls on oily pavement. Paved areas prevent water from sinking into the soil beneath them and create deluges of polluted runoff that strip away topsoil, contaminate waterways, and eventually disrupt ecosystems for miles around all paved human developments.

Are Extruded Houses Green?

For several years, Professor Behrokh Khoshnevis at the University of Southern California has been working on systems for rapidly creating buildings with system that is essentially a very large 3-dimensional printer.  Called Contour Crafting, the equipment is able to rapidly build up walls.  Already, test runs have been able to produce six-foot high concrete walls.

Weighing the Value of Concrete Housing

A South African company called Moladi is promoting their system for quickly building homes. Using their system, the exterior walls for a single-family dwelling can be built in a matter of just a day or two, and it can be done using unskilled labor. But, while their goals are admirable, it’s a question whether or […]

Design Competition for Greener Concrete

The Association of Collegiate Schools of Architecture (ACSA) and the Portland Cement Association (PCA) have announced their “Concrete Thinking for a Sustainable World” student design competition. This is the third year for the competition. The concrete industry is looking for opportunities to boost the perception of concrete as a green material, since the mining, processing […]
