			(hat tip: Abe Connally) Brick, stone and concrete are materials strong in compression but weak in tension. Nowadays, this problem is solved by steel structures or the use of steel-reinforced concrete (the tensile strength of steel is significantly more than that of bricks, stone or plain concrete). Pre World War II, the weak tensile strength of brick was compensated for by superior craftsmanship. The '''timbrel vault''' technique was cheap, fast, ecological and durable. These structures are similar in appearance to [[ferrocement]] but rely on entirely different materials and technique. Basically, a vault is built using tiles, and this requires very little formwork. The tiles then become the form for the roof. This technique was brought to the United States by the Guastavino family from Catalonia. In the OSE context, the tiles could be produced by a machine like the Liberator. There is at present very little experience with using compressed earth tiles ("CETs"?) in Guastavino-type masonry. The question is whether CETs will deliver adequate structural performance, similar to fired tiles. This should be addressed by performing side-by-side comparisons of fired tiles vs. compressed earth tiles.
