Ferrocement?

[eplabi]

Going crazy! Where on earth do you buy ferrocement?

 

[anaitis]

You don't buy it, you make it on site.
It consists of reinforcement and concrete with fairly fine aggregate.
The reinforcement is usually also thin but dense, can be mesh plus bars.

A few years ago, it was popular to build boats in that way.

Boats too!

Well, I understand that it's done on site. By the way, it's about a boat. The fact remains that it must be purchased somewhere. The question is where?

Try to get hold of this book:
Your Boat in Ferroplank: [Ferrocement Boat Builder's Handbook]
Written by Lars Wiklund
If you're lucky, it might be available at your library, otherwise, you can look in second-hand bookstores or maybe Tradera.

Many shop at Byggmax, but there are many who sell cement and reinforcement. These are completely ordinary building materials you're supposed to buy. Ballast is bought at a gravel pit.

Ferrocement is, just as anaitis writes, not a finished product. The name probably comes from all the thin iron reinforcement in the finished product - ferro is Latin for iron.

Ferrocement is therefore nothing but cement and a heck of a lot of fine reinforcement if I've got it right.

Ok, I get it. Thanks for the information! However, I read somewhere that the reinforcement in this concrete mix should be a much finer sand than what's mixed into regular concrete. Someone called it gipssand. What is that, and is it possible to get large quantities at the right price? Maybe "stenmjöl" could work?
