Abstract

A cementitious composition useful for water-resistant construction materials includes about 10 wt.% to about 35 wt.% fiber and about 65 wt.% to about 90 wt.% of a cementitious binder. The binder further includes about 30 wt.% to about 75 wt.% calcium sulfate beta-hemihydrate, about 10 wt.%
to about 50 wt.% Portland cement, and about 4 wt.%
to about 20 wt.% silica fume.
