Material experiments; metal and concrete

Researching possibilities of using metals embedded in concrete. I like how some of the metal shapes are a bit hidden; it goes with an idea I am looking at about fossils.

Concrete and metal fossil experiments

Lead snail and concrete

Lead star and concrete

The star could refer to the fossils of the very early sponges (eiffelia globosa) found in the middle cambrian age. The curled snaily shape a more recognisible fossil form. The pipes remind me of the snouts of pipe fish or clusters of tube corals.

Aluminium tubes and hollow in concrete

Not all the experiments were successful; this one had too high a proportion of metal slices to concrete; the hollow – although I liked it aesthetically – weakened the structure too much.

Proportion of metal to concrete too large; this experiment cracked
