An actual simple concrete pillar, with concrete body and a steel beam on the top. Approx 1 meter high.  The kind of base for vertical wood or metal pillars. 
Made by hand, based and photographed on a real one. Photo-real, high definition textures (around 6000 px).

Mainly worked for Cycle render. The shader's nodes let you tweak all textures via Color Ramps. Color texture with RGB Curve and Hue Saturation nodes.
