Yep, and all thanks to one of the least known and potentially greatest building material known to man: alkalai-activated aluminosilicate cement concrete.

Strong, very long lasting, chloride rsistant, environmentally friendly, fast setting, dimensionally stable geopolymers should be available everywhere, like down at your local Builder's Emporium. But, I bet it's not.

This is one technology that just can't seem to make it into the commercial world. Why not? Because of building codes.

A nine-man spall-repair team from the 455th Expeditionary Civil Engineer Squadron spends more than two hours every day maintaining the runway. A spall is a shallow break in the concrete, usually found along a joint.

“We’ve made more than 200 repairs in the last two months,” said Tech. Sgt. Jason Benbrook, the noncommissioned officer in charge of airfield maintenance who’s deployed here from Andersen Air Force Base, Guam. “This is an ongoing effort to support the mission until the new runway is completed.”

Um, has anyone thought of maybe building another runway? I hear some airports have more than one.
