Abstract
A cement composition comprising fine aggregate, preferably sand, in an amount of about 10 to about 25 wt %; blast furnace slag cement, in an amount of about 20 to about 35 wt %; gypsum, in an amount of about 20 to about 35 wt %; Portland cement, in an amount of about 4 to about 30 wt %; and cement plasticizer in an amount of about 0.3 to about 3 wt %. The dry cement composition may be formulated with aggregate and water to prepare a flowable liquid, self-leveling and self-smoothing coating material that may be applied to a substrate such as a floor substrate. The applied coating requires no manual finishing or smoothing, yet hardens to form a level, very smooth coating that possesses excellent compressive strength.
