casting concrete pieces

small piece of decorative cast concrete that came out of the plastic-lined mold on the right

Casting in 3 steps: multiple pieces being cast in sequence on the casting table. The farthest mold has the rebar in it, the middle box has been filled with cement mix, the front piece has had its mold removed revealling the cement object

Many of the larger pieces are like three dimensional jig saw puzzle pieces into which a number of smaller pieces will insert and lock into place

Pieces are left draped in wet burlap to slow down the drying process so the cement can continue its curing (chemical process that hardens the materials and bonds them together)

Pieces of column cylinders left to cure
