How to Build a Concrete Geodesic Dome
Concrete Canvas Ltd. manufacture a ground breaking material technology called Concrete Canvas that allows concrete to be used in a completely new way. Concrete Canvas was originally developed for the award winning Concrete Canvas Shelters, a building in a bag that requires only water and air for construction. Concrete Canvas is a flexible concrete impregnated fabric that hardens on hydration to form a thin, durable water proof and fire-resistant concrete layer. Essentially, it’s concrete on a roll. Concrete Canvas Shelters are rapidly deployable hardened shelters that require only water and air for construction. A CCS25 variant can be deployed by 2 people without any training in under an hour and is ready to use in only 24 hours. ncrete Canvas - Civil applications of Concrete Canvas ncrete Canvas - Civil applications of Concrete Canvas

Dome Homes made of concrete Dome Homes made of concrete When I first heard of these remarkable structures, I was a little hesitant, to say the least, who including me, wanted to live in a "cement igloo"? It was similar to a geodesic dome, but without the flat spots. How things have changed since that first 20' diameter dome home 8 years ago.

SUPER-STRONG......up to 225 mph Hurricane Winds & Category 4 Tornado Guarantee The dome's geodesic shape combined with the steel reinforced concrete exterior allows for such a guarantee. Ai's standard design will accommodate up to 225 mph hurricane winds, category 4 tornadoes and 75 lb. snow loads. In over 35 years, Ai domes have survived all major USA hurricanes (Andrew & Katrina), tornados, a Hawaiian earthquake, and a 30" in diameter hickory tree impact with no structural damage.

A couple things any prospective purchaser of this book should be aware of. First, it is published by one of those on-demand web publishing concerns, thus, the quality is basically what you would get if you printed it off of your PC printer. Secondly, the book is very short, by it is OVERWHELMINGLY LOADED with the authors rants and ravings that have very little to do with actual concrete dome construction. Matter of fact, I would say that 50% of this book is actually dedicated to concrete dome construction, while the rest is made up of "folksy advice" that has precisely zero to do with building a concrete dome.Sorry, I don't need someone to tell me to "get a lawyer" when buying land or "go with my gut instinct" when hiring contractors. I bought this book to learn about how to build concrete domes- not advising me that in order to feel comfortable in my office, I "should never have a door to my back- I guess so no one could sneak up on you..."

THIS FERROCONCRETE DOME COST ONLY $400! THIS FERROCONCRETE DOME COST ONLY $400! It certainly ain't a mansion, but this cute little concrete dome home built by Jill Abrahamson and Charles Buell in upstate New York has already provided the young couple with snug quarters through a frigid winter. The structure rests on a 3'-deep 14"-wide foundation trench that was filled up to ground level with fieldstone and concrete. (Jill and Charles now feel that either a concrete slab or a series of 8" piers spaced two feet apart would have made an adequate — and simpler — foundation.)
Peter's Concrete Block Dome Peter's Concrete Block Dome Peter Roberts has been building a unique dome structure in the woods and is sharing it with us. I discovered Peter when he posted a picture on the Tiny House Blog’s Facebook page. Peter’s inspiration came from throwing giant pots. Peter was throwing large pots, and they became architectural, it prompted him to investigate ceramic houses, this led to the masonry system you see in these pictures. Peter graduated from the NYS College of Ceramics at Alfred University with a degree in Masonry Science. Peter combined his experiences in Fine Art and Ceramic Engineering.
Why build a concrete dome? The concrete dome is similar in shape and structure to an egg which has always been a fascination. The egg shows us that a relatively soft and weak material can be used to create a very strong structural shape. A simple demonstration illustrating the strength of an egg was made using a 2′ × 10′ wood plank, supported on one end by a rigid support and on the other end by one hard boiled egg. Four bags of Portland Cement were placed on the plank, at center span, one at a time, for a total of 376 pounds or 188 pounds on one egg. The shell did not crack! Such is the strength of some domes.
