Abstract
A cementitious composition useful for water-resistant construction materials, including floor underlayments, backing boards, self-leveling floor materials, road patching materials, fiberboard, fire-proofing sprays, and fire-stopping materials includes about 20 wt.% to about 75 wt.%
calcium sulfate beta-hemihydrate, about 10 wt.% to about 50 wt.% Portland cement, about 1 wt.% to about 20 wt.% silica fume and about 1 wt.% to about 50 wt.% pozzolanic aggregate. The Portland cement component may also be a blend of Portland cement with fly ash and/or ground blast slag.
