Thank you @HandyDan. The 1500°F is the characteristic of Portland Cement I wanted to know. Certainly land management in planning for such an event is only right if building in a forested area. I know those with buildings in or near Yosemite and Glacier National Parks would appreciate knowing this information at this time.

A follow-up question would be then, is there a type of cement available which can withstand a higher temperature without getting real exorbitant in cost, but will still mix well using the Little Dragon?

When considering building in heavily forested areas the statement that aircrete is "fireproof" begs the question: Aircrete is fireproof to what temperatures?

Looking up temperatures at which forest fires burn ( http://wildfiretoday.com/2011/02/26/at-what-temperature-does-a-forest-fire-burn/ ): "Under extreme conditions a fire can give off 10,000 kilowatts or more per metre of fire front. This would mean flame heights of 50 metres or more and flame temperatures exceeding 1200°C (2,192°F)". Is aircrete able to withstand SUSTAINED temperatures of 1200°C (2,192°F)?

Therefore, will an aircrete dome remain fireproof to these temperatures?
