If Martian “Darwin” Is Not Concrete, What Is Concrete?

% of readers think this story is Fact. Add your two cents.
Mars rover Curiosity took these images of the “Darwin” site (note 1) on Mars on Sol 390 & Sol 392:
SIX RED RECTANGLES MARK REMNANTS OF CONCRETE PAVEMENTS CONSTRUCTED BY ADVANCED MARTIANS. ALL OVER MARS ARE NUMEROUS SUCH CONCRETE PAVEMENT REMAINS. IMAGE CREDIT: HORTONHEARDAWHO. See also: http://www.gigapan.com/gigapans/140117 ( See the white-balanced image at right.)

“Remains of the old historic Coast Highway 101 in California”. GREEN ARROWS AND RED RECTANGLES MARK CONCRETE PAVEMENT REMAINS RESEMBLING THOSE AT ''DARWIN” SITE ON MARS.

“Adding more images to the (CURIOSITY) Mastcam100 Sol-395 Panorama.” RED AND GREEN RECTANGLES MARK REMNANTS OF CONCRETE PAVEMENTS AND CONCRETE BLOCKS, RESPECTIVELY. FEW BIG OBJECTS HERE HAVE THE SHAPES OF COMMON ROCKS.

Surface texture of degraded concrete on Earth:
FIGURE SHOWS “Concrete surfaces with different depths of erosion”. RED RECTANGLE SHOWS SURFACE (DEPTH = 0 mm) OF DEGRADED (ERODED) CONCRETE. THERE ARE OTHER KINDS OF CONCRETE SURFACES. IMAGE SOURCE: http://www.cement.org/tech/cct_dur_acid.asp
Other kinds of eroded surfaces of concrete on Earth:
THERE ARE MANY KINDS OF TEXTURES ON WEATHERED CONCRETE. WEATHERED CONCRETE SURFACE MAY BE CONTAMINATED WITH CELLULAR FOSSILS, CORALS, ETC. IMAGE SOURCE: http://www.sciencedirect.com/science/article/pii/S0167844298000627
