Hi oc Flexible reinforce concrete is needed. Most sky scrapers
are made with poured concrete,and sway a lot in a hurricane 165 mph
wind. They don't crack. Reality is cement can be made with lots of
different features to fit the job.Saw a sail boat on lake Toho was made
of continuos concrete. Very smooth looking and can't leak.Owner told me
it was easy and fast to build. Its frame was chicken wire shell. This is
exactly like the stucco homes in Huntington Beach are made,and they
stand up to earthquakes Well oc it is just an idea. I like the burn
away material used in capsule rentry the best. Its been proven it works
every time. Beert
