Domestic concrete

Until a few weeks ago, this subject held up a fence post in my back yard. Then the wind blew. When it stopped blowing, I needed a new fence. Several passes with a diamond blade and a few sledgehammer blows later, this chunk of stuff came out. It wasn't big enough to have much choice in composition, but I thought the colors and patterns were pretty enough to show anyway.

24 mm wide. Sawed flat, sanded smooth on 400-grit paper, flooded with water to photograph.

A much more creative use of concrete than a lot of buildings I've seen . IMO it make an interesting piece of art in a "So what am I looking at?" kind of way. Hmmm, I reckon it would look pretty good on the wall, framed at about A3.

Not that it matters particularly, however just out interest could you give us an idea of scale.

WOW, they use some pretty nice aggregate in the concrete out west . Up close you would think it was a real conglomerate.

Ha, gotcha! This time I took a shortcut and left off the graphic scale bar. Size was at the bottom of the text: "24 mm wide".

Now you know how terrazzo is made! I see some bits of marble in there I think?

...and I read that line too!

I have no idea what's in this stuff. The local gravel deposits are a thoroughly scrambled mess of sedimentary, metamorphic, and volcanic types, all mixed together by some enormous floods at the end of the last Ice Age.

All I can really tell you is that this stuff cut OK with a diamond blade, but something in it reduced a carbide masonry bit to a blunt-ended rod!
