FibreC: Thin Slab Concrete Siding that May Settle the Wood vs. Brick Debate

I grew up in Northern California, and I suppose I like the look of structures clad in wood because they’re comfortable and familiar. Wood works wonderfully in that earthquake-riddled part of the country because it’s flexible and can handle the forces imparted by the occasional seismic event better than a brick facade.  Brick is great, but it can’t be denied that it will undergo a complete nervous breakdown when placed under unusual stress. More often than not, wood faced with lateral forces takes a deep breath, squares its shoulders, and carries on with the vital business of protecting building interiors …

A Dutch Machine that Lays Brick like an Unrolled Carpet

Every once in a while I like to find out about a new way to use a very old material, like brick for instance. Human beings have been working with brick at least since the times when the flooding of the Euphrates might engender the total destruction of the walls Gilgamesh built around his city, so the material definitely qualifies as ancient.  And I found out about a rather interesting way that a Dutch company, Tiger Stone, has been laying brick: they are rolling roads out like carpet.

I have no idea …

How to Grow a Chair out of Crystals!

“Nature shows us a beauty that exceeds our imagination. On the other hand, it contains a strength that is sometimes frightening. The forms of nature are unique and cannot be reproduced. This endows them with mysterious beauty and makes them fascinating to us”.
– Tokujin Yoshioka
I’m a big fan of sitting down in chairs, and like many Americans, I do it for hours at a time.  Don’t get me wrong, I don’t mind laying down or standing up, or sitting cross-legged on the floor – those positions are nice and everything. …

3D Printed Stabilized Sand: Air Hive Cooled by Evaporation

You don’t dance on a bee hive and sprint headlong into the house chased by a swarm of angry bees without developing a healthy respect for the sanctity of apidae habitat.  I didn’t mean to dance on the hive; I was only four years old and I had no idea it was even there until eighteen million bees erupted out of what I had thought was an innocuous stone-ringed mound of dirt.  The fact that such a small earthen bump could house that many insects is a testament to the …

BacillaFilla: Bacteria that Repair Cracked and Damaged Concrete

 
Joints are like an after-school program for cracks in concrete. If we fail to provide a place for cracks to occur safely, under supervision, and in aesthetically pleasing configurations, we as a society will be faced with complete anarchy in our walls and slabs.  This horrifying chaos could lead to unwed, underage cracks begetting more cracks and, possibly even more alarming, cracks on crack.
Sometimes, despite the provision of joints and reinforcing in concrete to resist tension, construction goes horribly wrong. Say the mix is off, or the wrong strength is used by mistake, or perhaps …

New: Biodegradable Foam made from Milk Protein and Clay

If I were about to be shot from a cannon like one of those people at the circus who are routinely shot from cannons, I’d wear a sumo-sized foam suit and I’d also demand that the spot where I’d expect to land would be covered in fluffy chunks of foam as well.  I’d want foam strewn pretty much everywhere to absorb the force of my impact because I don’t enjoy the prospect of danger.  I guess that’s why I’m not a circus performer.  Let’s face it: people wouldn’t exactly be thrilled watching someone being shot from …

Antibacterial Tiles that Clean and Sanitize Themselves

Think of public restrooms as the Arctic expedition, Sahara desert traverse, or trek through the Amazon of architecture; the public restroom is one of those extreme environments where you plan for the worst and hope for the best.  Your typical public toilet faces all possible byproducts of humankind, harsh chemical cleaners, random acts of vandalism, water, fungus, insects, rodents, and the full spectrum of microorganisms.  Ceramic materials are specified in public restrooms because smooth glazed surfaces are easier to keep clean and damaged tiles can be replaced without too much trouble, but the chemicals required to sanitize public …

CalStar Fly Ash Brick “Comes in Eight Colors. All of them Green.”

 
When I first heard the term “fly ash” in architecture school, I remember thinking that it sounded pretty sick.  I mean, flies are annoying and it’s gross when they buzz over and land first on some unidentified, dog-generated substance on the ground and then, without a single shred of consideration, approach and settle on the rim of your drinking cup or slice of pecan pie.  But it boggles the mind to think about the enormous number of flies you’d have to crisp in order to produce so many metric tons of fly ash that there’d even …

New Synthetic Adhesives Derived from… Oysters?

Never have I felt even the slightest desire to slurp down an oyster.  Not once have I looked said bivalve in the eye*, so to speak, and been able to overcome my not inconsiderable revulsion long enough to taste one.  It seems however, that I’m in the minority; many of my dearest friends are completely mad for oysters and eat them in copious quantities whenever they can get their hands on them. 
I bring this up because tasting good (to other people, at least) is a positive characteristic of oysters.  Another positive …

Carbon Cast Concrete

Carbon fiber is one of those futuristic-sounding, expensive materials that I associate with supersonic airplanes, fancy road race bicycles, and $400,000 dining tables.  So imagine my surprise when I found out that, back in 2003, a group of precast concrete companies banded together with carbon fiber grid provider Chomarat to form AltusGroup, who manufacture a product called Carbon Cast Concrete.  “AltusGroup members use Chomarat’s C-GRID®, as the carbon fiber epoxy based reinforcing in several precast building system products to enhance the strength and reduce the weight of precast concrete” (Drabestott).  Reinforcing humble precast concrete with …
