I read this earlier thread and we have just come upon Zonatile that failed in an industrial building. I was wondering if anyone has any info on it

Please describe the material as the term "Zonotile" might be a misspelled term as noted in the other thread. Please give the age of the building and the manifestation of failure. Photos would be helpful as well.

it is called Zonatile manufactured in the 50s and 60's. Its a light concrete roof plank 18"X36". It was manufactured by W.R. Grace out of Chicago. Heres some literature.

DCEB...thanks. Zonatile was manufacturered by the Zonolite Company which was purchased by W.R. Grace in the early 1960's. They apparently dropped Zonatile from their product line 4 or 5 years later.

I'm wondering if it did not compete well with cast-in-place gypsum and Tectum decks that were popular in that era.

The info you have is probably as good as you'll get!
