08/30/2013 - Heat Treating Calcium Silicate and Cement Board Materials
Suggested Heat Treating Cycle for Calcium Silicate and
Red Seal has added a suggested heat treating cycle for its
Calcium Silicate and Cement Boards to the redseal.com website. The document can be accessed below and also
via the Literature option on the web site’s home page.
The Calcium Silicate boards include Marinite P and Marinite
I. Although Marinite A is also a calcium
silicate board, it is heat treated by the manufacturer, BNZ Materials. Cement boards requiring heat treatment
include Transite HT and Transite 1000 also from BNZ.
The procedure slowly increases the temperature of the
material over a 10 or more hour period and then slowly allows the material to
cool. In the process, any moisture in
the binding materials is slowly evaporated.
Heating the material rapidly (to say 1100 degrees F) will cause a rapid
expansion of any moisture contained in the binders and may lead to cracking and
cause the material to smoke.
