Re: [PSUBS-MAILIST] wire and acrylic
Hello Bill
Ferrocement is a special technique or form of using
cement or concrete.
A good site is :
www.ferrocement.com
There you find a good explanation. With ferrocement
you can build houses, tanks, boats and even submarines
like the yellow october, a very funny experiment.
Best wishes
Jürgen
